Diffuse cutaneous leishmaniasis in HIV.

Cutaneous leishmaniasis is caused by the intracellular protozoan parasite belonging to the genus leishmania and is characterized by a myriad of clinical lesions including papules, nodules, and ulcers. Diffuse cutaneous forms of leishmaniasis are rare. We report a rare case from South India of diffuse cutaneous leishmaniasis masquerading as lepromatous leprosy in the context of HIV infection.
