Shistosomiasis is a chronic parasitic illness caused by Shistossoma Mansoni, responsible for 200 million cases all over the world. The most common presentation is hepatic-intestinal form with symptoms as diarrhea, tenesmus, hepatomegaly, abdominal pain and nausea. We report a case of a male patient, 38 years with anal polyp prolapse, confirmed by colonoscopy, located in the sigmoid. The patient was submitted to sigmoidectomy, which through a histological study of the surgical specimen a giant shistosomal granuloma of the colon was evidenced. The aim of this report is to describe a rare and atypical manifestation of a case of shistosomosis.
