Cutaneous leishmaniasis (also known as oriental sore, tropical sore, chiclero ulcer, or chiclero's ulcer) is the most common form of leishmaniasis affecting humans. It is a skin infection caused by a single-celled parasite that is transmitted by the bite of a phlebotomine sandfly. There are about twenty species of Leishmania that may cause cutaneous leishmaniasis.
