Histopatologia da leishmaniose tegumentar por Leishmania braziliensis braziliensis: 1. Padrões histopatológicos e estudo evolutivo das lesões

Abstract: RESUMOOs autores analisam material de biópsias de 378 casos de Leishmaniose Te¬ gumentar, causada por Leishmania braziliensis braziliensis, da localidade endêmi-ca de Três Braços (Estado da Bahia). O parásitos, embora escassos, foram encontrados em 63,7% dos casos da forma cutânea e em 37,5% dos casos da forma mucosa. As alterações dérmicas ou do córion da mucosa permitiram identificar cinco padrões histopatológicos: 1) Reação Exsudativa Celular, constituída por um infiltrado histiolinfoplasmocitário; 2) Reaçã… Show more

“…During infection with Leishmania parasites, the development of clinical lesions coincides with the influx of inflammatory cells such as macrophages, eosinophils, and neutrophils (2,3,34). In Lb infection, patients displaying lymphadenopathy without ulceration exhibited a higher proportion of neutrophils and eosinophils in lymph node aspirates (35).…”

“…N ew World cutaneous leishmaniasis, caused by Leishmania braziliensis (Lb), 3 is distinguished from other leishmaniasis by its chronicity, latency, and tendency to metastasize in the human host (1). During infection with Lb, development of clinical lesions coincides with an influx of inflammatory cells such as macrophages, eosinophils, and neutrophils (2,3).…”

“…The evaluation of lesions of the animals inoculated was conducted through the evolution of the weight difference between the right and left ears (Moratti & Henriques 1990) of the sacrificed mice, and by the histopathologic analyses, by using a scale from 0 to 6, according to the inflammatory infiltrate intensity (Magalhães et al 1986). …”
