A 64-year-old Korean man presented with a several-year history of an itchy lesion on his penis. There was no history of trauma, and he denied recent changes in the size, shape, or color of the lesion. He also denied dysuria or other similar lesions elsewhere on his body. He had applied various topical medications in the past, without relief. He felt well overall, took no medications, and had no significant medical history.
Physical examination revealed a 2 × 4-cm, pink to red, thick, lichenified plaque along the median raphe of the midshaft of a circumcised penis (Figure 1). Some areas were covered with adherent scale. Subtle macular hyperpigmentation surrounded the plaque. The findings of the rest of the complete skin examination were normal. There was no inguinal adenopathy.
