title: Porokeratotic Adnexal Ostial Nevus-Report of a Case With Unusual Clinical and Histologic Features.
abstract: An 11-year-old Tanzanian girl presented with diffuse verrucous lesions of varying morphology, scarring alopecia, and keloid scars over the face with a predilection for the ears. Physical examination revealed dark keratoderma and patches of hypopigmentation near the midline of the dorsal trunk (Figure 1a). Her forearms were densely covered by verrucous lesions with the exception of a clear linear patch on the dorsal aspect of the left forearm (Figure 1b). The perioral area was notable for white spires projecting from verrucous papules (Figure 1c) while the oral mucosa and teeth appeared normal on visual examination. The rest of her body, including the palms and soles, was covered by patchy, scaly lesions of varying severity.
