RESUMO
Amoeboma is an inflammatory mass of the colon. It can be an inaugural symptom and thus pose the problem of differential diagnosis with colon cancer. The purpose of this report is to describe the case of a 43-year-old patient who presented with acute abdomen. Physical examination revealed a perforated circumferential mass in the sigmoid colon. Based on a presumptive diagnosis of colonic cancer complicated by perforation, segmental colectomy was performed. Histological examination of the surgical specimen demonstrated colonic amoeboma. The patient was treated using metronidazole. Although rare, amoeboma must be considered in differential diagnosis of cancer of any colonic mass.

Taenia saginata infection is caused by the bovine tapeworm and can be the cause of emergency surgical conditions. We report one case of small bowel obstruction leading to necrosis and another case of large bowel obstruction and volvulus due to an impacted tapeworm. The diagnosis of these rare circumstances is usually made intraoperatively.

The authors report a case of a 25 year old Brazilian man with a history of crampy abdominal pain in the left iliac fossa for 2 weeks, abdominal distention, mucous diarrhea and anorexia. The patient presented signs of hemodynamic instability and a hard mass palpated in the left iliac fossa presented peritoneal irritation. At laparotomy, fecal peritonitis and a punched-out perforation of the midsigmoid colon were found. A left hemicolectomy was performed with terminal colostomy. Specimen examination revealed a thickened rectosigmoid wall, narrow lumen and multiple mucosal polyps. Microscopically, chronic granulomatous colitis with Schistosoma mansoni eggs confirmed the etiology. To the authors'knowledge, this is the first case of obstruction complicated with perforation due to mansoni schistosomiasis reported in the literature.

A case is presented of peritoneal hydatidosis with fistulization into the sigmoid in a patient who had previously undergone surgery for hepatic hydatidosis. The clinical picture made its debut as an alteration in intestinal habit followed by the appearance of diarrheic syndrome and expulsion of hydatid membranes. The natural history of peritoneal hydatidosis, its complications and therapeutic guidelines are discussed.
