Penile horn: A rare presentation of pseudoepitheliomatous, keratotic, and micaceous balanitis successfully treated with oral acitretin
Abstract
Glans penis is an unusual site for horn. Only few cases are reported worldwide in English literature. Pseudoepitheliomatous, keratotic, and micaceous balanitis (PKMB) is a pyodermatitis with pseudoepitheliomatous response to chronic inflammation or infection. Rarely it can develop a horn. There is one case report of PKMB presenting as penile horn and one case with nail-like presentation in the literature. Mode of treatment of PKMB with horn ranged from topical 5-fluorouracil, electrosurgery, and cryosurgery to excision. Use of oral acitretin in PKMB or penile horn is unknown. We are reporting a 60-year-old circumcised male who presented with a penile horn. Histology was suggestive of PKMB. Treatment with topical 5-flurouracil did not work. He was successfully treated with oral acitretin.
