Resumo: Sixty skin biopsies of fifty-eight non-treated patients with cutaneous leishmaniasis from Nicaragua were studied. Biopsies were classified according to Ridley's histopathologic groups: 36 (60%) were included in group B (diffuse necrosis), 14 in group C (focal necrosis), 7 (11.6%) in group D (reactive tuberculoid). Only three biopsies remained unclassified. None of our cases could be included in groups A and E. Immunohistochemistry disclosed in 17 cases Russel's bodies secreting IgM and only one IgG positive. There was no correlation between the histopathologic groups and the presence of Russel's bodies. However, we believe the presence of Russel's bodies help the diagnosis of leishmaniasis. Correlation between morphological patterns and the different leishmania species was also considered.

Foram estudadas 60 biopsias cutâneas de 58 pacientes nicaraguenses com leishmaniose tegumentar e ainda não em tratamento terapêutico. Quase todas as biopsias foram classificadas nos grupos histopatológicos de Ridley: 36 (60%) foram incluídas no grupo B ("diffuse necrosis"), 14 (23%) no grupo C ("focal necrosis"), 7 (11.6%) no grupo D ("reactive tuberculoid"). Somente 3 biopsias ficaram sem classificação. Não se achou nenhum caso que se pudesse classificar nos grupos A e E. Em 18 casos, usando método imunohis-toquímico, foram observados corpúsculos de Russel. Destes 18 casos 17 eram IgM positivos e só 1 IgG positivo. Não se descobriu correlação entre os grupos histopatológicos e a presença de corpúsculos de Russel. Todavia se imagina que os corpúsculos de Russel possam ter um significado diagnóstico (como um critério adjunto). Pode-se supor também uma correlação entre as numerosas alterações morfológicas e as diferentes espécies de leishmanias. Universidade de São Paulo.
