Pseudoepitheliomatous, keratotic, micaceous balanitis. A clinical lesion with two histologic subsets: hyperplastic

Abstract:
A 58-year-old man presented with a 4-year history of a slowly enlarging, hyperkeratotic plaque on his glans penis that was compatible with a clinical diagnosis of pseudoepitheliomatous, keratotic, micaceous balanitis. The lesion had been treated unsuccessfully on three occasions with superficial shave excisional biopsies. Complete surgical excision produced excellent cosmetic and functional results with no evidence of recurrence at 3- and 6-month follow-up. A diagnosis of verrucous carcinoma was made on histologic examination of the excised material. Pseudoepitheliomatous, keratotic, micaceous balanitis is a distinctive clinical entity that represents a histologic spectrum ranging from hypertrophic-hyperplastic penile dystrophy to verrucous carcinoma.
