A 40-year-old man presented with a nonhealing ulcer on the right hand of 2 months' duration. The lesion had started as a pruritic papule while he was visiting Guyana 2 months prior. The area had slowly enlarged with progressive ulceration. He denied any systemic signs including fever, chills, or weight loss, and his medical history was unremarkable. Physical examination revealed a 4-cm fungating ulceration with heaped-up borders on the dorsal aspect of the right hand.
