Atopic dermatitis is an inflammatory skin disorder characterized by erythema, edema, pruritus, exudation, crusting, and scaling. Presentation. In infancy the patient may present with an erythematous, pruritic rash with weepy patches on the cheeks, neck, wrist, hands, and extensor aspects of the extremities. Atopic dermatitis in infancy frequently coincides with introduction of foods.

Necrolytic Migratory Erythema

This rare dermatosis occurs most frequently on the genital skin and lower abdomen. The distinctive eruption consists of an erythema with erosions, vesiculation, and bulla formation. The rash extends outward with healing and crusting at the outer edge. Postinflammatory pigmentation is common. There is also an associated weight loss, glossitis, and angular cheilitis. The patient may also have diabetes. Histologi-cally, there is marked epidermal necrolysis and a mild dermal lymphocytic infiltrate. It is nearly always associated with an underlying pancreatic glucagonoma. The dermatosis resolves with treatment of the glucagonoma and correction of nutritional deficiencies secondary to malabsorption (Table 15).

Cancers Related to Specific Mutations eg Retinoblastoma Ataxia Telangiectasia

Some cancers are associated with specific gene mutations. I have already mentioned retinoblastoma, which occurs when the tumor suppressing the RB gene is lost or altered. Another disease, ataxia telangiectasia (AT), is caused by a recessive gene. AT patients have increased sensitivity to ionizing radiation and often develop leukemia or lymphoma. Their heterozygous relatives have an increased incidence of breast cancer. There are other cancers associated with inherited defects of specific genes, and some patients with these defective genes also have higher risks of developing breast cancer. These conditions are extremely rare.

Ataxiatelangiectasia Ai2

Ataxia-telangiectasia is transmitted as an autosomal recessive trait. The defect is found on the long arm of chromosome 11. Ataxia begins shortly after children learn to walk. It is progressive, and patients end up in wheelchairs by age 10-12 years. Telangiectasia first appears at 3-6 years of age and can occur anywhere, but is typically on the bulbar conjunctiva. Patients have chronic upper respiratory infections and deficient cellular immunity (low or absent IgA and IgILlymphopenia). They are at higher risk for malignancies such as Hodgkin, leukemia, and sarcoma. Growth deficiency manifests in infancy or childhood. Patients develop ataxia, choreoathetosis, drooling, and a masklike fades. Nystagmus may be seen. Death occurs because of serious pulmonary infections or neurologic deficit.

Erythema Multiforme

Erythema multiform (figure 1-11) is an acute inflammatory condition that is easily observed because of a redness of the mucosa or the skin. It occurs in many forms on various parts of the body. Young adults are most commonly affected. The oral mucous membranes are frequently involved, including vesicle rupture that leaves painful oral ulcerations. The lips often exhibit crusted ulcerative lesions. Lesions appear rapidly (within 10 to 14 days) and persist several days or longer. The symptoms are treated, with spontaneous remissions occurring. Recurrence is common. if areas other than the skin and the mucous membranes are involved (such as the eye or the genitalia), the possibility of a syndrome complex exists.

Examination Of Nosesinuses

Inspect the external nose and look for redness, edema, lumps, tumors, or poor alignment. A patient with red nostrils may blow the nose frequently because of allergies or infectious rhinitis. Dilated, engorged blood vessels of the nose may indicate either that the patient is outside in all kinds of weather much of the time or that he is an alcoholic. A person with a bulbous, discolored nose may have rosacea (a chronic inflammatory disorder similar to acne).

Acute Lymphocytic Leukemia

The peak incidence for acute lymphocytic leukemia (ALL) is 3-4 years of age. It is more prevalent in white children than in black children. Children with conditions such as Down syndrome, ataxia telangiectasia, von Recklinghausen, and sideroblastic anemia are at risk for developing ALL. Being a twin sibling of a leukemic patient younger than 4 years of age also increases the chances of a child to develop ALL. Children with solid tumors, such as Hodgkin disease and Wilms tumor, or those who have undergone intense treatment may develop leukemia as a secondary malignancy (more commonly AML acute myelogenous leukemia ).

Laser Resurfacing with the ErbiumYAG Laser

Erbium Laser Before And After

Red or pink color is a universal feature of healing skin and is to be expected after erbium YAG (and CO2) laser resurfacing. This color (termed erythema) is due to dilated capillaries. Capillaries dilate during wound healing, and the degree and duration of erythema after laser resurfacing is significantly less with the erbium YAG than with the CO2 laser. Like all other differences between these lasers, this is because of the relatively minimal heating of the skin from the erbium YAG laser. For most people, this color is more pink than red and fades rapidly over the next few weeks frequently the color is normal within one month. Facial areas with deeper wrinkles, which require more intensive treatment, will have greater and longer-lasting erythema. Most women prefer wearing makeup to cover the pink color and may do so within one week of the resurfacing procedure. Makeup effective for this purpose is widely available.

Fungal Infections Candidiasis

Vulva Insert

Erythema of the Most often, the physical examination only shows vestibular erythema. However, more severe infections exhibit more of the following vulvar abnormalities erythema, edema of the modified mucous membranes, a superficial, shiny glazed texture, fissuring of skin folds, peripheral scale and peeling, and satellite red papules, pustules, and collarettes (circular scale that represents the edges of a desquamated blister roof) (Figs. 17 and 18). The vagina may or may not exhibit erythema. Although vaginal secretions are generally reported as a dry cottage cheese'' consistency, vaginal secretions are often normal clinically. Variable from no abnormalities on examination to vulvar erythema, edema, scale, collarettes, vaginal redness. Vaginal secretions sometimes white and clumped, always with fungal elements microscopically

Physical Examination Ocular Signs

Episcleral Tissue

A hallmark finding that distinguishes scleri-tis from episcleritis is the presence of scleral edema. Edematous sclera can bow forward, displacing the deep episcleral vascular plexus and exacerbating deep vascular congestion. To assess the degree of scleral involvement, blanching the superficial conjunctival and episcleral vasculature with topical 2.5 phenylephrine can improve visualization of the underlying tissue. Further examination using a red-free filter is instrumental in evaluating the vascular architecture, areas of avascularity, and cellular infiltration of the episclera. The anatomic location of the inflammation and typical alterations in the vessels form the basis of the classification of anterior scleritis 45 . Nodular anterior scleritis can present with a single or multiple scleral nodules (Fig. 5.4). Typically, the nodule is a darker hue of red, separate from the overlying episclera, immobile, and tender to palpation. These features distinguish this form of scleritis from...

Parasitic Infections Trichomonas

Bacterial vaginitis (not vaginosis) produce vestibular and vaginal cervical erythema and vaginal secretions with similar microscopic findings. However, the causative organism is absent. The diagnosis is made by the setting and the identification of the organism microscopically.

Removing Vascular Skin Lesions

A telangiectasia is a visibly dilated, linear blood vessel. Telangiec-tases, which may be associated with a diffuse redness or blush due to accompanying microscopic capillaries, occur primarily on the face and may be associated with a skin disease such as rosacea. Rosacea is an acne-like condition that occurs in adults. People with rosacea experience frequent flushing (blushing) of facial skin. During flushing, facial blood vessels dilate, producing visible redness. Many vessels eventually become permanently dilated (telangiectases). Telangiectases also frequently occur as a consequence of excessive sun exposure.

Staphylococcus aureus

Staphlococus Disease The Vaginal

Impetigo primarily affects children and there is no predilection for the genital skin. These lesions are characterized by very superficial vesicles produced by a staphylococcal toxin. The vesicle ruptures and leaves behind a superficial erosion and the development of a yellow crust surrounded by a base of erythema when occurring on keratinized skin (Fig. 9). The lesions are multiple and of varying duration. Erythema,

History Ocular Symptoms

Analgesics and can be associated with malaise and weight loss, leading to misdiagnoses such as sinusitis, migraines, and brain tumour. Disten-tion of the nerve fibres secondary to scleral edema and necrosis of nerve endings are speculated to be responsible for pain that can be so severe as to awaken the patient. The most severe pain, often out of proportion to the extent of inflammation, is seen with progressive necrotizing scleri-tis, which can be a stark contrast to the absence of pain in scleromalacia perforans. The eye may feel tender to palpation due to the inflammation 45 . However,tenderness is generally not experienced in necrotizing scleritis without inflammation. In contrast to scleritis, episcleritis is not associated with significant pain or tenderness. Scleritis typically has a gradual onset of redness with increasing inflammation over several days 45 . In contrast to the brighter redness of episcleritis, scleritis is usually a darker violaceous-red hue due to the depth...

Recommended Outcomes to Measure Healing After Thermal Injuries

A variety of macroscopic and microscopic outcomes can be used to measure healing of burns. Early indicators include infection based on the presence of erythema, purulence, or systemic indicators of infections such as fever. Microscopically, infection is defined by the presence of intradermal neutrophils containing bacteria. While this measure has a high degree of reliability (6,8,9), it does not necessarily indicate clinically relevant infections and may be overly sensitive (16).

Inflammatory Dermatoses Eczema

Desquamative Inflammatory Vaginitis

Vulvar eczema is characterized by erythema and scaling on the outer labia majora and erythema and fissures and erosions on the inner aspects. Vulvar eczema is pruritic, often out of proportion to the clinical findings. The skin may become ede-matous, excoriated, and lichenified because of scratching.

Appendiceal Stump Odematous Colonoscopy

Appendiceal Stump Coloscopy

Oedema and erythema are possible due to repetitive trapping of the mucosa in a contraction of the colonic wall. These lesions can be the cause of recurrent bleeding. Imaging findings are equivocal. As on the axial and endoluminal 3D images, they present as a polypoid lesion, and the polyp- simulating mucosal prolapse syndrome is indistinguishable from actual polyps. On conventional colonoscopy these lesions, appearing as a hyper-aemic mass, are also difficult to distinguish from adenomatous polyps. Sometimes these ambiguous lesions are only diagnosed after biopsy with histology showing hemosiderin-laden macrophages, capillary thrombi and congestion with telangiectasia (Mathus-Vliegen and Tytgat 1986).

Laser Resurfacing with the CO2 Laser

Cold Sore Crusting Stage

Most patients largely heal within ten days. For several days after the epidermis has re-grown, there is significant peeling of the epidermis, producing a dry appearance. This flaky skin is treated with an ointment type moisturizer (Aquaphor). The great majority of patients are able to return to work within two weeks after resurfacing. There is always redness (erythema), which has the appearance of a sunburn. This redness will fade to pink but is usually maximal about one month following surgery. By two months following surgery, the pink color will be much lighter and usually fades completely within three to four months.

Soft Tissue Infections

GAS may invade the epidermis and subcutaneous tissues, resulting in local swelling, erythema, and pain.17 The skin becomes indurated and, in contrast to erysipelas, is a pinkish color. Patients with lymphedema secondary to lymphoma, filariasis, or surgical node dissection (mastectomy, carcinoma of the prostate, etc.) are predisposed to development of GAS cellulitis, as are those with chronic venous stasis and superficial dermatophyte infection of the toes. Saphenous vein donor site cellulitis may be due to group A, C, or G streptococci. Cellulitis associated with a primary focus (e.g., an abscess or boil) is more likely caused by S. aureus. Aspiration of the leading-edge and punch biopsy yield a causative organism in 15 and 40 of cases, respectively. Patients respond quickly to penicillin, though in some cases where staphylococcus is of concern, nafcillin or oxacillin may be a better choice, or one may need cover for methicillin-resistant S. aureus (MRSA) infection (discussed later in...

Pediatrics and Neonatology

The answer is c. (Behrman, 16 e, pp 1950-1959. Ludman, pp 1-8.) The most likely diagnosis in this patient is acute bacterial otitis media. A mucopurulent discharge in acute otitis media occurs only if the drum perforates otherwise, the tympanic membrane is bulging and erythematous. The organisms responsible for this infection are Haemophilus influenzae, Streptococcus pneumoniae, and Moraxella catarrhalis. Adenopathy is usually absent in simple otitis media. Perforations of the eardrum may occur with infections sudden changes in pressure, especially when diving and trauma. Serous otitis media will cause the tympanic membrane to be retracted and scarred. Acute mastoiditis is caused by the breakdown of the thin bony partitions between the mastoid cells and occurs when an otitis media continues, often with few symptoms, despite adequate treatment. Patients have a continuous discharge through a perforation in the eardrum and complain of swelling, tenderness, and erythema over the...

The answer is d. (Victor, p 1483.) The violaceous, or purplish, discoloration developing around the eyes is called a heliotrope rash (after the flower that has similar coloring). These patients also have erythema over the knuckles. A target-shaped lesion on the limb suggests Lyme disease. Adenoma sebaceum and shagreen patches are skin changes typical of tuberous sclerosis. Telangiectasias over the malar eminences, conjunctivae, and ears occur with ataxia telangiectasia. 331. The answer is d. (Victor, pp 1482-1488.)

This rash surrounds both eyes and may extend onto the malar eminences, the eyelids, the bridge of the nose, and the forehead. It is usually associated with an erythematous rash across the knuckles and at the base of the nails and may be associated with flat-topped...

Clinical Features

One of the first indications of infestation is intense itching. Pruritus indicates infestation of about two months' duration. The lice are difficult to see in clean individuals who have only a minor infestation. Yet they can be abundant and easily, seen in malnourished individuals with poor hygiene. Nits can be confused with dandruff and may be distinguished from it with a magnifying glass. Also dandruff falls from the hair easily whereas nits firmly attach to it. It should also be distinguished from seborrhea, psoriasis, the shafts which cover the hair in the pityriasis sicca or from the residual particles of hair spray. On examination of hairy skin, it is possible to see lichenification and severe scratching marks and erythema, especially in the occipital or retroauricular regions (Fig. 41.4). If a white cloth is place under the head of an infested child and a fine-toothed comb is drawn through the hair, lice, easily nits or ova, and a black powder-like lice...

Exfoliative dermatitis

Exfoliative dermatitis (erythroderma) can complicate a number of dermatological and systemic problems, including psoriasis (especially following steroid withdrawal), atopic dermatitis, contact dermatitis, ichthyosis, drug eruptions and lymphoma. Its most generalized form is called the Stevens-Johnson syndrome (see Erythema multiforme).

Erythema infectiosum is a benign, self-limited exanthematous illness. Risk Factors Etiology. The etiology of erythema infectiosum is parvovirus B19, a DNA virus. Humans are the only known host, and they transmit the virus via respiratory secretions and blood. This disease is commonly seen in the spring. The incubation period ranges from 4 to 28 days. Diagnostic Tests. The diagnosis of erythema infectiosum is usually made clinically. Laboratory tests for the diagnosis of B19 are not available routinely. Detection of viral DNA in fetal blood aids in making the diagnosis of B19-induced fetal hydrops. Complications. Patients with hemolytic anemias such as sickle cell anemia are at risk for aplastic risis if infected with parvovirus B19. Fetuses exposed to erythema infectiosum may develop fetal

The biochemical properties of the components of the signal transduction pathways

Mutations in the genes encoding these proteins leads to checkpoint signaling defects in yeast 24, 36 and in humans mutations in NIBRIN and MRE11 lead to a cancer-prone syndrome similar to that of ataxia telangiectasia 13, 115 . The proteins in this complex are also targets of the Mecl kinase and its orthologues. It remains to be determined whether other proteins that are involved in lesion processing and repair are also involved in checkpoint signaling, and if this role is different from their role in generating the single-stranded DNA that could act as the signal 124 to recruit other sensor complexes (see below).

Confirmatory Procedues For Mycobacteria

Animals that are negative for this test will demonstrate only a slight erythema.

Chapter Summary continued

Cirrhosis is an end-stage liver disease due to many etiologies characterized by disruption of the liver architecture by bands of fibrosis that divide the liver into nodules of regenerating liver parenchyma. Complications of cirrhosis include portal hypertension, ascites, hypersplenism, esophageal varices, hemorrhoids, caput medusa, hepatic encephalopathy, spider angiomata, palmar erythema, gynecomastia, hypoalbuminemia, decreased clotting factors, and hepatorenal syndrome.

Autonomous parvoviruses

A parvovirus that does not require a helper virus was discovered in serum from a healthy blood donor. The virus, named after a batch of blood labelled B19, infects red blood cell precursors. Many infections with B19 are without signs or symptoms, but some result in disease, such as fifth disease (erythema infectiosum), in which affected children develop a 'slapped-cheek' appearance (Figure 12.2).

Response To Uv Light

The role of vitamin A as a sunscreen has also been suggested. Antille et al. (2003) have reported that human skin, treated once daily for 2 days with 2 retinyl palmitate, was protected against UV light-induced erythema. A sun protection factor (SPF) of 20 was associated with application of 2 retinyl palmitate. In addition, application of retinyl palmitate protected against UV light-induced DNA damage. Subsequent studies showed that absorption of UV light, rather than effects on retinoid-responsive genes, gave rise to the observed protective effects (Sorg et al., 2005).

Allergic Manifestations

Adverse Reaction to Drug Absorption. Ingestion of certain drugs by individuals having an idiosyncrasy or intolerance to them may result in the allergic manifestations referred to as stomatitis medicamentosa. The signs in the mouth vary from a sensitive erythema (redness) to an ulcerative stomatitis or gingivitis. If withdrawal of the suspected drug is followed by disappearance of the lesions, it is evidence of its causal relationships. Therefore, treatment consists of identification and elimination of the drug causing the lesions. c. Adverse Reaction to Contact With Drugs. While the lesions of stomatitis medicamentosa are the result of absorption of drugs, the lesions of stomatitis venenata are caused by the direct contact with a drug or a material. Causative agents of stomatitis venenata may be topical medications, dentifrices, or mouthwashes. Intraoral signs may vary from a sensitive erythema (redness) to an ulceration. Treatment consists of...

Antimigraine Antiemetic and Anti Parkinson Drugs

The coiontophoresis of metoclopramide and hydrocortisone has been proposed to decrease the local irritation caused by the antiemetic as it passes through the skin (78). The pharmacokinetics of metoclopramide after iontophoretic delivery in vivo in man were not modified by the coadministration of hydrocortisone. However, the codelivery of hydrocortisone was sufficient to reduce the erythema and edema observed.

In Vivo Noninvasive Investigation of the Skin

The alterations of skin functions following the application of high-voltage pulses have been evaluated directly in vivo in hairless rat using noninvasive bioengineering methods (Vanbever et al., 1998b) (Fig. 7). In agreement with the visual evaluation, mild but transient erythema was measured by laser Doppler flowmetry and

Nonsurgical Lasers for Treating Skin

Prior to the development of the pulsed dye laser, the argon laser was the best option for treating blood vessels. Introduced in the 1970s, the argon laser produces blue-green light with a wavelength of 514 nm. This color is well absorbed by the hemoglobin molecule in red blood cells and is near a peak in the absorption spectrum of hemoglobin (fig. 4.1), and thus has a selective effect on vascular tissue. This laser was used primarily by ophthalmologists to destroy abnormal blood vessels in the retina that occur in diseases such as diabetes and can lead to blindness if untreated. The argon laser was used with some success to treat cutaneous blood vessels. Most responsive were large facial vessels (telangiectases), which are common in people with the acne-like skin disease rosacea and can also occur in people who have had excessive chronic sun exposure. The physical and optical properties of port wine stains are different from those of telangiectases such that treating them with the...

Pathways To Cancer From Replication Defects

Ataxia telangiectasia 159 Ataxia-telangiectasia-like disorder (Mre11), Nijmegen syndrome (Nbs1) 35 Checkpoint genes are important gatekeepers of genome stability 59 . Mutations in the ATM checkpoint kinase are linked to ataxia telangiectasia 159 , and mutations in the checkpoint kinase Cds1 (also called CHK2) are found in a subset of patients with Li-Fraumeni syndrome 10, 12 . In addition, Rad17 (one of the checkpoint rad proteins) is overexpressed in certain types of human cancers 9 . The corresponding S. pombe proteins (Rad3, Cds1, and Rad17) are all involved in the cellular response to replication blocks 25 . The S. pombe Rad4 Cut5 protein, which also has a role in cellular checkpoints 156 , contains a BRCT motif that is also present in the human BRCA1 tumor suppressor and the XRCC1 DNA repair protein 44, 157 . Thus, mutations that disrupt function of the replication checkpoint are also implicated in predisposition to cancer.

Macroscopic Description of Burns

Initially the deep partial-thickness burns have a pale white appearance with a surrounding rim of erythema that subsides within several minutes (Fig. 2). Within the next few days the burns become red and develop a thick scab that does not allow direct observation of the reepithelialization underneath the scab. As a result, we rely on tissue biopsies for evaluation of the degree of reepithelialization. This is in contrast to human burns, in which direct visualization of the neoepidermis is usually possible, allowing the observer to follow the progression of reepithelialization. We (as others before) have not observed blister formation in the pig under any of the studied experimental conditions.

Genital Ulcers Vulva

Lipschutz's ulcer, which occurs in young women, is a separate entity. This is usually one large deep painful ulcer that develops very rapidly and is covered with an adherent slough. The ulcer is sited most frequently in the inner aspect of one of the labia minora. Occasionally, two ulcers develop at apposing sites bilaterally (Fig. 15). The ulcer heals spontaneously over several weeks leaving some scarring. The Lipschutz-type ulcer is sometimes associated with a systemic infection such as infectious mononucleosis (34-36), typhoid, or paratyphoid fever. Healing is spontaneous but may take several weeks and leaves some scarring. Differential diagnoses include Herpes simplex infection with type 1 or 2, erythema multiforme, and Langerhans cell histiocytosis.

Within four to seven days after exposure, a tender papule arises. Within another one to two days, the lesion becomes pustular or ulcerates (Fig. 8). The ulcer is extremely painful and surrounded by erythema, and it is often foul smelling. Lesions can be solitary or by autoinoculation form multiple lesions that can coalesce into kissing lesions or giant ulcers. Within one or two weeks, inguinal lymphade-nopathy develops in approximately 50 of patients and is usually unilateral. The lymphadenitis may become suppurative and rupture. If untreated, extensive ulceration, necrosis, genital and perineal edema, and rectovaginal fistulae can result. ding erythema

General Pathology

A 22-year-old female presents with the sudden onset of a high fever, a diffuse erythematous skin rash, and shock. She started menstruating at age 13 and for several years has used tampons. Which one of the following is the most likely diagnosis for this individual's illness a. Ataxia-telangiectasia

Bacterial Vaginitis

Vaginal Discharge Strep

Bacterial vaginitis can occur in any age group, but group B Streptococcal infection is found primarily in the well-estrogenized vagina, and alpha hemolytic Streptococcus is seen most often in prepubertal girls, sometimes in association with perianal streptococcal dermatitis. Bacterial vaginitis is most often characterized by irritation, burning, and dyspareunia, although some patients describe itching. Women often report a yellow vaginal discharge, but odor is not prominent. Vestibular and vaginal erythema is usual, and a yellow or yellow green vaginal discharge is present (Fig. 15). The vaginal pH is high, and a microscopic examination of a wet mount shows a high proportion of immature epithelial cells and a striking increase in neutrophils. Lactobacilli are generally absent. In the event of a group B Streptococcal infection, chains of cocci are often evident (Fig. 16).

A 25-year-old heterosexual man develops a urethral discharge and dysuria 5 days after having unprotected sexual intercourse with a new partner. Physical examination reveals meatal erythema. There are no penile lesions and no inguinal lymphadenopathy. A purulent ure-thral discharge is evident. Gram stain of the discharge reveals neu-trophils and intracellular gramnegative diplococci and the patient is treated for Neisseria gonorrhoeae. Two weeks after antibiotic therapy (ceftriaxone intramuscular injection), the patient returns with a clear urethral discharge and dys-uria. Gram stain reveals many neu-trophils but no organisms. Which of the following is the most likely diagnosis 429. A 19-year-old previously healthy college student presents with a 5-day history of fever, generalized malaise, and sore throat. He denies cough. He does not use illicit drugs and uses condoms with his one sexual partner. He has been vaccinated against hepatitis B. On physical examination the patient...


Formerly known as lichen sclerosus et atrophicus, lichen sclerosus is a chronic der-matologic condition that is more common in women and may involve both vulvar and extragenital lesions. Patients typically present with severe itching and may also report burning and dyspareunia. The entire vulvar area may be involved, including the clitoris and perianal regions. The skin often has the typical parchment appearance with white papules and plaques that may appear crinkled. Fissures, telangiectasias, and stenosis of the introitus may occur. With long-standing disease, there is often alteration of the normal vulvar architecture resulting in absence of the labia minora, adhesions of the labia majora, and phimosis of the clitoris in extreme cases. While it can affect women of any age, it is more commonly seen in the postmenopausal years and approximately 10 to 15 of cases occur in pediatric patients (2). This category includes lichen simplex chronicus and epithelial hyperplasia, and in the...

Vulvitis Pictures

This is a syndrome of recurrent oral ulceration accompanied by two of the following genital ulceration, eye lesions including anterior uveitis and retinitis, other cutaneous lesions, i.e., erythema nodosum, sterile pustules, erythema multiforme, and pustu-lation at sites of trauma (pathergy). It is a multisystem disorder (37) and there may be gastrointestinal, neurological, psychiatric, rheumatological, cardiological, and pulmonary involvement. Vascular complications include superficial and deep vein thromboses, arterial occlusions, and aneurysms (Fig. 16). Vulvar ulcers occur less frequently than the oral ulceration and they are clinically similar to benign aphthae although they may be larger and or more numerous and tend to last longer. They heal with scarring. Diagnosis is sometimes difficult and often only made as the clinical signs and complications evolve over a period of time. The geographic distribution of cases suggests either local endemic agent or physician overacceptance...

A diagnosis of erythema multiforme is made. The most important information obtained from this patient's history is 405. A 45-year-old man with Parkinson's disease has macular areas of erythema and scaling behind the ears and on the scalp, eyebrows, glabella, nasolabial folds, and central chest. The diagnosis is 407. A 33-year-old fair-skinned woman has telangiectasias of the cheeks and nose along with red papules and occasional pustules. She also appears to have a conjunctivitis because of dilated scleral vessels. She reports frequent flushing and blushing. Drinking red wine produces a severe flushing of the face. There is a family history of this condition. The diagnosis is d. Acne rosacea b. The most likely diagnosis is erythema multiforme

Wound infection

Erythema Oedema Cellulitis is an acute, rapidly swelling inflammation of the skin and soft tissues (Grey 1998). It is characterised by swelling, pain, erythema and heat, and sometimes fever. These signs are usually confined to the area around the wound, but in some severe cases it may be accompanied by features of systemic toxicity, including septicaemia. It often occurs after minor breaks in the skin, lacerations, surgical wounds and ulcers.


Neurolathyrism Images

Many plants cause an irritant contact dermatitis. Simple mechanical irritation through spines or prickly hairs is one method by which plants cause human disease. The thorns of a flowering plant or spines of a cactus can penetrate the skin and cause fungal (Sporothrix), bacterial (Staphylococcus aureus), and other disease.84 Chemical irritants are produced by some plants and can cause dermatitis. The manchineel tree, Dieffenbachia, and Philodendron are examples of plants that exert their toxicity through chemical irritation. Acute clinical findings include erythema, edema, and papular and vesicular reactions. In severe cases, bullae, pustules, and ulcerations may occur. Treatment of mechanical and chemical irritants revolves around removal of the irritating stimulus. This may include manual removal of thorns or copious irrigation of the skin to remove chemical irritants. Phytophotodermatitis occurs when the skin is exposed to both a plant toxin and ultraviolet radiation. Celery,...

Localized Disease

Undermined Wound Borders

In Australia, the initial lesion occasionally presents as a painless pustule less than 1 cm in diameter with erythema in the surrounding skin.42 The pustule may progress to a major ulcer. This type of BU lesion has not been reported in Africa or any endemic country other than Australia.


The answer is a. (Fitzpatrick, 3 e, pp 314-318, 332-335, 401-405, 877-882.) Erythema multiforme (EM) minor due to the herpes infection is the most likely diagnosis in this patient. The lesions of EM are classically target lesions they are burning and pruritic. They are generalized and often involve the oral mucosa. Etiologies of EM major include drugs such as phenytoin, sulfonamides, barbiturates, and allopurinol. Finger pressure in the vicinity of a lesion in EM major leads to a sheetlike removal of the epidermis (Nikolsky sign). Pemphigus vulgaris is a chronic, bullous, autoimmune disease usually seen in middle-aged adults. The Nikolsky sign is positive in pemphigus vulgaris. Secondary syphilis appears 2-6 mo after a primary infection and consists of round to oval, maculopapular lesions 0.5-1.0 cm in diameter. The eruptions typically involve the palms and soles. Secondary syphilis lesions that are flat and soft with a predilection for the mouth, perineum, and perianal areas are...


The answer is b. (Tintinalli, 5 e, pp 1556-1559.) The patient has a peritonsillar abscess, which is an accumulation of pus between the tonsil-lar capsule and the superior constrictor muscle of the pharynx. Patients present with a hot potato voice, fever, cervical lymphadenopathy, trismus, and a displaced uvula due to a unilaterally enlarged tonsil. Patients complain of dysphagia, odynophagia, and otalgia. A retropharyngeal abscess is an infection of the deep spaces of the neck (from the base of the skull to the tracheal bifurcation) patients are often young children who present with fever, cervical lymphadenopathy, neck pain, neck swelling, torticollis (rotation to the affected side), difficulty breathing, and stridor.

Raoult, p 785.) Parvovirus B 19 is the causative agent of erythema infectiosum (fifth disease). It is associated with transient aplastic crisis in persons with hereditary hemolytic anemia. In adults, it is also associated with polyarthralgia. 7. The answer is c. (Murray, pp 912-918.) All of Koch's postulates have been verified for the relationship between infectious mononucleosis and Epstein-Barr virus, a herpesvirus. However, the relationship between this virus and Burkitt's lymphoma, sarcoid, and systemic lupus erythematosus (SLE) is less clear. Infectious mononucleosis is most common in young adults (14 to 18 years of age) and is very rare in young children. There is 48. The answer is b. (Levinson, pp 221-222.) Parvovirus B19 causes the common disease erythema infectiosum, characterized by a slapped cheek rash. Called fifth disease, it is the fifth childhood rash disease the other four are measles, rubella, scarlet fever, and roseola.

Was shown to occur in 3.5 of patients. In addition, delayed hypersensitivity was demonstrated in 1.3 of patients 3, 12-14 . These reactions resulted in localized erythema and induration. While less than desirable in dermal applications, this type of reaction could have potentially devastating results in the larynx or airway, an off-label use of bovine collagen products therefore, it is recommended that patients have a small test dose planted in the forearm and be observed for 6 weeks prior to clinical use. This problem has always tempered the use of bovine collagen products, particularly in the larynx 14 . A comparison of collagen products is given in Table 8.2.1.

PE regional lymphadenopathy (axillary lymph nodes enlarged) mild neck stiffness neurologic exam normal large (6- to 8-cm), annular, erythematous lesions with central blanching seen over left arm and trunk ( ERYTHEMACHRON1CUM MIGRANS) no enanthema. Lyme disease is a tick-borne (Ixodes tick) illness caused by the spirochete Borrelia burgdorferi. Tick reservoirs include deer and mice. Lyme disease is divided into early disease (stages 1 and 2) and late disease (stage 3) stage 1 is characterized by the presence of a distinctive skin lesion termed erythema migrans (EM, or erythema chronicum migrans). Stage 2 is a disseminated phase of infection with manifestations in the skin, CNS, musculoskeletal system, and heart. Late disease, or stage 3, reflects persistent infection that is clinically manifest more than one year after the onset of disease. This stage most often involves the skin, joints, and CNS.

The Skin and Aging

Yet another sign of chronic sun damage is the dilation of facial blood vessels (these enlarged vessels are called telangiectases). Such enlarged vessels are especially common around the nose and in central facial areas. The vessels enlarge enough to become visible as discrete, linear blemishes. Although frequently referred to as broken blood vessels, telangiectases are intact, functioning vessels. Chronic sun damage is the most common cause of facial telangiectases, but rosacea, a common skin disease that causes frequent flushing (blushing) reactions, can also cause them.

3 About the third day after vaccination, a papule appears at the vaccination site. The fifth or sixth day this papule becomes a vesicle (small blister). Erythema (redness of the skin) and induration (a spot which is abnormally hard) follow and start to subside about the tenth day, followed by a crust formation which comes off after about 21 days. The primary reaction may be accompanied by lymphadenopathy (lymph node enlargement), fever, and malaise (a general feeling of bodily discomfort).

While not typically associated with any lesions apparent on the vulva, vulvodynia should be considered in the differential for complaints of chronic vulvar itching and or burning. Generalized vulvodynia generally manifests as chronic, unprovoked vulvar burning in menopausal women but may be provoked. Localized vulvodynia presents with pain restricted to the vestibule, or other focal area, and provoked with pressure or touch to the area but may be unprovoked. While women with vulvodynia localized to the vestibule may have erythema of the vestibular mucosa at times, these disorders are thought to be due to neuropathic pain and therefore are not usually associated with significant physical findings on examination.


The dermatitis is referred to as necrolytic migratory erythema and is sufficiently characteristic for dermatologists to be responsible for most diagnoses of glucagonoma. The initial skin lesion is a reddish macule which then vesiculates and finally sloughs leaving an area of local hypopigmentation. These lesions are seen especially on the buttocks, groin and distal extremities. Sometimes the entire sequence of lesions can be found simultaneously. There is a characteristic histology, with inflammatory cells in clefts. The skin lesions occur early in the course of the disease, even before metastases, and disappear within a few days of successful resection. A generalized decrease in serum amino acid levels may be responsible for this unusual dermatitis.

CAllergic Reactions

(1) Allergic reactions following blood or plasma transfusions occur less frequently than leukocyte chill fever reactions and are usually relatively mild. Most consist of local erythema, hives, and itching which develop during transfusion and that can be easily treated with, or prevented by, administration of antihistamines.


Side effects of IFN-a therapies are the development of anti-thyroid antibodies, sometimes leading to thyroiditis, and anti-DNA antibodies. Since increased IFN-a and anti-DNA antibodies are also found in patients with lupus erythema-todes, it is a major concern that IFN-a treatment even has the potential to induce SLE. Most patients experience flu-like symptoms, which resolve spontaneously.

Brown Spiders

The actual bite is usually painless, and therefore few offending spiders are identified. Within several hours, pruritus, tingling, mild swelling, and redness or blanching at the site may develop.90,93 During this time, as local tissue ischemia develops, variable pain and tenderness are noted. Within 12 to 18 hours, a small, central blister (clear or hemorrhagic) often forms at the site, surrounded by an irregular zone of erythema or ecchymosis and edema. Within a few days, aseptic necrosis is evident at the bite site with an overlying black eschar. When the eschar sloughs, an open ulcer or crater is left, which may require weeks to months to heal.90,93 Bites are most severe in fatty regions of the body (buttocks, thighs, etc.).93 Necrosis rarely involves deeper, more vital structures such as muscles or nerves.94 Treating physicians faced with a patient with a necrotic wound of unclear etiology should be very careful not to label it as a brown recluse bite unless the offending spider...

Local Reactions

The most frequent adverse side effect associated with adjuvanted vaccines is the formation of local inflammation with signs of swelling and erythema, and symptoms of tenderness to touch and pain on movement. Such reactions occur more frequently in preimmune individuals, or after repeated immunization (24). The inflammation is thought to be the result of formation of inflammatory immune complexes at the inoculation site by combination of the vaccine antigen with preexisting antibodies and complement, resulting in an arthus-type reaction. Such reactions tend to occur more frequently after adjuvanted vaccines than after aqueous vaccines because of the high antibody titers induced by adjuvants.

Lyme disease

Humans are inoculated through the skin giving rise to erythema migrans, in which the organism can be identified in nearly 90 of cases. The organism then disseminates to the joints, heart and CNS. The disease has protean manifestations, and probably many cases are unrecognized. Infection occurring during pregnancy may cause fetal damage or fetal death at any stage.

Delayed Reactions

After several hours or a few days, some vaccines may produce local reactions (induration, erythema, and tenderness) at the site of the injection. These reactions may be accompanied by systemic reactions consisting of fever, headache, malaise, chills, gastrointestinal upset, and other related symptoms. Symptomatic treatment with antipyretic and analgesic drugs and rest is usually adequate. a. Typhoid Vaccine. Reactions to typhoid vaccine include pain, erythema, induration, and swelling. Fever, myalgia, headache, and malaise may also be manifested. Typhoid vaccine should not be given with other vaccines that may produce similar reactions. This vaccine should also be avoided during febrile illness, intensive physical activity, and during high environmental temperatures. c. Plague Vaccine. About ten percent of the people receiving plague vaccine will experience general malaise, headache, local erythema (skin redness), and induration (an abnormal hard spot), mild lymph node involvement,...


Adverse reactions to Ty21a are minimal. These may include abdominal discomfort, nausea, vomiting, fever, headache, rash, or urticaria. Adverse reactions to the ViCPS vaccine are also minimal fever (0 -1 ), headache (1.5 -3 ), and local reactions of erythema of induration of 1 cm or greater (7 ) have been reported.

AVM can be solitary (40 of cases) or multiple, often associated with hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome). Diagnosis can be reliably confirmed by CT or MR examinations, showing a vascular mass with a large feeding artery and draining vein (Fig. 4.4). Catheter angiogram is indicated only as a part of the current treatment of choice, i.e., embolotherapy.


Any symptoms and signs of sepsis in a patient with a vascular graft should alert the clinician to the possibility of a graft infection. With a subcutaneous graft, localized erythema and cellu-litis or a discharging sinus may be clinically visible over the length of the graft, or prosthetic material may be visualized eroding through the skin. With a deep infected graft (e.g., an aortic graft), the patient may present with vague symptoms and have pyrexia of unknown origin. An infected aortic prosthesis may form an aor-toduodenal fistula and present with upper gastrointestinal bleeding that may be mistaken for peptic ulceration. Less commonly, lower gastrointestinal hemorrhage may be seen from aortoenteric fistulas into distal bowel sites. Alternatively, signs of septic emboli to the extremities may present as a purpuric rash. Other more rare sequelae of a graft infection included metastatic mycotic aneurysm formation, anastomotic pseudoaneurysm formation, or anastomotic hemorrhage. With...

Visual Evaluation

Visual evaluation of skin after high-voltage pulse exposure has been carried out in in vivo related studies, i.e., transdermal drug delivery, electrochemotherapy, and gene therapy (Prausnitz et al., 1993b Vanbever et al., 1998b Okino et al., 1992 Titomirov et al., 1991). These studies generally reported mild, transient erythema and or edema over the area of electrical contact with the skin. No burn Mild reversible erythema

Thermal Effects

It can be seen that it is extremely difficult to predict the amount of tissue heating that will develop during a specific sonication regimen although temperature elevations of several degrees centigrade are typical. The temperature rise will increase the fluidity of stratum corneum lipids as well as directly increase the molecular diffusivity of the permeant molecule through this layer. Both these effects will enhance drug transport in vitro. In the in vivo situation, ultrasonic energy will pass into deeper tissues, increasing the tissue solubility of drugs as well as initiating increased microvascular perfusion, i.e., hyperemia. The magnitude of the hyperemic reaction in human skin can be measured by using a water bath as a variable heat supply and a photometric sensor to quantify the extent of induced erythema. Figure 3 shows the response profile that is typically obtained.

Physical examination reveals enlarged, erythematous tonsils with exudate and enlarged, slightly tender cervical lymph nodes. Presentation. Viral and bacterial pharyngitis are often difficult differentiate clinically. Erythema, exudate, petechiae, enlarged tonsils, and cervical adenopathy may be common to both. Viral pharyngitis usually has a gradual onset, with moderate throat pain and symptoms of URI. Many times a history of contacts having cold symptoms can be elicited. Vesicles and ulcers are more common with herpes simplex and coxsackievirus. Conjunctivitis is seen with adenovirus. Viral exanthems may be seen. GABHS may present with headache, vomiting, and abdominal pain. URI symptoms are usually absent. Palatal petechiae and diffuse erythema of the tonsils and pillars are highly suggestive. Strep pharyngitis can be associated with a fine, blanching, erythematous,...

Skin Lesions

Skin lesions occur in 41-94 of cases and are morphologically diverse. Papulopustules, ac-neiform pseudofolliculitis and erythema no-dosa are most common, but pyodermia, ulcerations, necrotizing lesions, Sweet syndrome and superficial thrombophlebitis may also occur. Polymorphic erythema or pyoderma gangreno-sum and pernio-like lesions are rare. Different skin lesions can occur in the same patient, either sequentially or at the same time. Histologi-cally, there is a leucocytic vasculitis with perivascular infiltration by neutrophils and fewer lymphocytes. Even histologically, the differentiation between acne vulgaris and papulo-pustules of BD is difficult. Erythema nodosum, which, when associated with sarcoidosis or other disorders, represents a panniculitis, reveals vasculitic changes and an additional subcutaneous thrombophlebitis in BD. Immunohisto-logically, the infiltrate consists of T cells, NK cells and macrophages.

Kawasakis Disease

The condition begins with an acute febrile illness. This is followed by a polymorphic rash that may affect any part of the body, congestion of the conjunctivae, dryness and erythema of the oral mucosa, cervical lymphadenopathy, and erythematous edema of the palms and soles. These features are the criteria for the diagnosis of Kawasaki disease (Table 8.5). Other clinical features are outlined in Table 8.6.
