Inclusion criteria were a mucosal lesion and positivity of direct microscopic examination. The patients were investigated retrospectively. Results. - Patients with mucosal Leishmaniasis were young and mostly male The absence of treatment and the number of cutaneous lesions were probably responsible for the mucosal form, as well as the host immune response and maybe, the parasite species or vector characteristics.
