Foram examinados 231 indivíduos, observando-se: a) Sessenta e sete indivíduos (29%) apresentavam leishmaniose confirmada pela histopatologia das lesões cutâneas e intradermorreação de Montenegro. Destes casos, 40 (59,7%) eram homens; b) a idade variou entre 2 (5 casos) e 86 anos (1 caso); c) de acordo com o tipo de lesão, observou-se: 54 (80, 6%) pacientes apresentavam úlceras, 13 (19,4%) nódulos, 4 (5,9%) lesões úlcero-vegetantes e 3 (4,4%) cicatrizes típicas; d) a intradermorreção de Montenegro apresentou 94,7% de positividade nos casos de leishmaniose-doença. Este estudo reforça observações prévias de que, além da forma clássica de transmissão, a leishmaniose pode ser transmitida no intra e peri-domicílio.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.437-442porLeishmaniose tegumentarEpidemiologíaIntradermorreação de MontenegroArtigo10.1590/S0036-46651993000500009S0036-46651993000500009Acesso abertoS0036-46651993000500009.pdf188538440589304887894804583775527528116925519142
