Penile Horn: A Rare Presentation of Pseudoepitheliomatous, Keratotic, and Micaceous Balanitis Successfully Treated with Oral Acitretin.Indian Dermatol Online J 2019 Jul-Aug; 10(4):460-462ID
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.
