Leishmaniasis is a tropical and subtropical disease caused by an intracellular parasite transmitted to humans by the bite of a sand fly, mainly Phlebotomus and Lutzomyia (Europe, Northern Africa, the Middle East, Asia, and part of South America); exceptionally, transmission has also been reported as a laboratory accident 1. According to the World Health Organization (WHO), leishmaniasis is one of the seven most important tropical diseases and it represents a serious world health problem that presents a broad spectrum of clinical manifestations with a potentially fatal outcome 2, 3. It is found in all continents except Oceania 2, 4 and is endemic in circumscribed geographic areas in Northeastern Africa, Southern Europe, the Middle East, Southeastern Mexico, and Central and South America.
The clinical features include a broad range of manifestations with different degrees of severity that depend on the species of Leishmania involved and the immune response of the host 3. In Mexico, the most characteristic form is the cutaneous-chondral form 1, 4, also called “chiclero’s ulcer”.
