Abstract
Figure 1. A: Suppurative lesion involving the ear pinna, with necrotic areas in the helix and, in a lesser degree in the anti-helix, infiltrative aspect in the lobe and papules in the pre-auricular region. Notice the lack of lesion in the external auditory canal inlet. B: Necrosis extending to the helix, infiltrative aspect in the adjacent skin and papule with central necrosis behind the ear, similar to the inoculation lesion. C: Granulomatous aspect seen in the bottom of the lesion after improvement in the suppurative process. Notice the persistence of papulae behind the year and the infiltrative aspect in the lobe and adjacent skin. D: Initial state of the ulcer healing process, about 20 days after treatment onset. E-F: Ear pinna reepithelialisation, 60 days after the end of treat- ment. Notice the improvement in the ear lobe and in the pre and retro auricular regions.

Mucocutaneous Leishmaniasis (MCL) has different clinical forms, depending on the leishmania species involved and its relation with the host[1]

We roughed up the borders of the lesion for a direct exam, and we found the leishmania in the amastigote form
