title: Condyloma with lichen nitidus.
abstract: A 32-year-old black man presented with two separate eruptions on his penis (Figure). He has had a 10-year history of asymptomatic 1-3 mm shiny papules on the shaft of his penis. He also has had one asymptomatic verrucous brown plaque 1.5 cm in diameter on his penis. A small shave biopsy was performed for each process. The former showed lymphocytes and histocytes in the papillary dermis in a "ball-in-claw" relation to the rete ridges of the epidermis. The latter showed an acanthotic epidermis with papillomatosis. Diagnoses of lichen nitidus and condyloma acuminata were respectively made. As the shiny papules did not bother the patient, but he wanted to be rid of the verrucous plaque, only the latter was treated. Liquid nitrogen was applied to the plaque. The patient was also given podofilox 0.5% gel to apply to the condyloma overnight on Monday, Tuesday, and Wednesday, with a 4-day respite. This cycle was to be repeated for 3 more weeks. He was examined several more times and treated with cryotherapy and podofilox gel with the near disappearance of the condyloma over 4 months.
