O câncer anal representa aproximadamente 2% dos cânceres colorretais. Nos últimos anos observa-se o aumento da incidência nos indivíduos HIV positivos. Este estudo teve como objetivo avaliar a prevalência de lesões intra-epiteliais escamosas anais (ASIL) em pacientes HIV+ procedentes de Manaus. Foram estudados 45 doentes HIV+ encontrando-se no exame histopatológico, os seguintes resultados: 15(35,7%) lesões de baixo grau, 3(7,1%) lesões de alto grau e 24(57,2%) negativos para ASIL. Houve, portanto, alta prevalência de ASIL, 42,8%. Concluímos que a prevalência de ASIL entre os pacientes HIV positivos, da amostra estudada, é muito importante, justificando-se a implantação de um programa de acompanhamento e detecção precoce, destas lesões; pois os pacientes HIV+ representam um importante grupo de risco para o desenvolvimento do câncer anal. The anal cancer accounts approximately for 2% of the cases of colorectal cancer. In the last few years it has been observed an increase in the incidence of this disease in HIV-positive individuals. The objective of this study is to evaluate the prevalence of anal squamous intraepithelial lesions (ASIL) in HIV-positive patients which are resident in Manaus. Forty-five HIV+ patients were included in the study, from which it was collected anal mucosal tissue for biopsy under anoscopic control using widened image for histopathological exam. According to this exam, it was found the following results: 15(35,7%) low grade lesions, 3(7,1%) high grade lesions and 24 (57,2%) negative for ASIL. Therefore, there was a high prevalence of ASIL, 42,8%. We concluded that the prevalence of ASIL among HIV-positive patients, in the studied sample, is very important, justifying the implementation of a program of precocious monitoring and detection of these lesions, as the HIV+ patients represent an important risk group for the developing of anal cancer
