New world cutaneous leishmaniasis.

A 24-year-old Bangladeshi man presented with a 12-week history of a pruritic papule on his left elbow that had enlarged and ulcerated. He was without any constitutional or systemic symptoms. He reported a history of extensive travel in the two years prior to presentation that included Bangladesh, South and Central America, and Mexico. Histopathologic features were consistent with leishmaniasis. Speciation by the Centers for Disease Control showed L. brasiliensis.
