title: [Outbreak of American cutaneous leishmaniasis in Itaporanga, São Paulo (Brazil)].
abstract: An outbreak of cutaneous leishmaniasis in a small rural settlement, located in the Southern of São Paulo State-Brazil was observed. This region has basic agricultural activities, and has no forests. Two hundred and thirty one persons were evaluated, and the following aspects were observed. 1) 67 individuals (29%) had skin lesions, confirmed by histopathologic study and the Montenegro skin test; 2) of these cases, 40 (59.7%) were males; 3) The youngest patients were 2 years (5 cases), and the oldest, 86 (1 case); 4) the following types of cutaneous lesions, were observed: a) 54 cases (80.6%) had ulcers, 13 (19.4%) had nodules, 4 (5.9%) had verrucose lesions, and 3 (4.4%) had typical scars. In all the cases, the parasite identified was Leishmania (Viannia) braziliensis. The vector captured in the region was Lutzomyia intermedia, a strong anthropophilic sandfly very frequently observed in São Paulo. This study shows that apart from the well-known outbreak observed in the forest environments, leishmaniasis can be transmitted within or around dwellings.
