Cutaneous Leishmaniasis in a Non-endemic Area in Mexico.

Leishmaniasis is a zoonotic disease caused by a parasite of the genus Leishmania endemic in 102 countries around the world. Clinical features can be classified as cutaneous, mucocutaneous, and visceral leishmaniasis; this will depend on the species of leishmania responsible for the disease and the immunologic response of the host. We present the case of a 14-year-old male who started with a small papular lesion in the helix of the left ear, which later spread to the rest of the helix, tragus, and part of the auricular concha.
