A 44-year-old man presented with a six-month history of a painful progressively enlarging nodule on the plantar surface of the left foot. He reported occasional bleeding and oozing of clear to yellow fluid. On a review of systems, he also noted fatigue, dizziness, and dark stool. Past medical history was significant for AIDS diagnosed three years earlier, with noncompliance regarding previously prescribed highly active antiretroviral therapy (HAART).

Physical examination revealed a discrete exophytic friable pink nodule coated with yellow crust on the central plantar surface of the left foot (Figures 1 and 2). No regional lymphadenopathy or edema was noted.

A shave biopsy from the left plantar foot was obtained for routine hematoxylin and eosin stain (Figures 3 and 4).
