The labium minus is always keratinized, that is, shows a stratum corneum, indicating skin rather than mucosa, on the lateral side (Fig. 8) (11). In our experience, the medial side is also always keratinized, although Jones found that keratinization was absent in 62% (11). Perhaps because the transition to vestibule may be vague, the allegedly mucosal part may be, in fact, vestibule.
Any parakeratosis is abnormal (11). The basal layer of keratinized labium minus may be pigmented and small rete ridges are present. Sebaceous glands are located superficially in the dermis and open directly onto the surface (Fig. 9). Like the labium majus, the epidermis and dermis of the labia minora are thicker in the reproductive age group. The frequency of sebaceous glands on both surfaces of the labium minus varies greatly. The dermis of the labium minus is composed of fine collagen and elastic fibers. Blood vessels and nerves are numerous. There are no hair follicles, eccrine or apocrine glands, or subcutaneous fat on any part of the labium minus.
