A 65-year-old man presented with a 6-year history of persistent asymptomatic erythema of the glans penis that did not respond to corticosteroid or antifungal creams. He had a history of rosacea and actinic damage, but his general health was good, and he had no medical issues or medications of relevance. He denied any history of trauma, irritation, or discharge from the area.

Examination revealed an uncircumcised penis with shiny, well-demarcated erythema of the glans extending onto the inner surface of the prepuce (Figure 1). Physical examination findings were otherwise unremarkable; no lymphadenopathy was seen. A punch biopsy specimen of the glans penis was taken for histologic examination (Figure 2 and Figure 3).
