Case report: Rectal perforation caused by Schistosoma haematobium

Abstract

A 31-year-old woman from Cameroon was admitted to the University of Strasbourg Hospital in December 2007 with pelvic pain and fever that developed over three days. Her condition rapidly worsened and she underwent emergency exploratory celioscopy. Surgeons found peritoneal and retrouterine abscesses. The high rectum had a 4-cm perforation with infiltrated, friable, and irregular edges. A biopsy specimen of this pseudotumoral specimen showed many Schistosoma haematobium eggs with an inflammatory reaction surrounding the eggs. The patient was treated with praziquantel (40 mg/kg/day) for 5 days and a 4-week course of antibiotic therapy. Her progress was good and digestive continuity surgery was performed four months later. Schistosomiasis frequently involves rectal mucosa, but perforation is unusual. Our review of the literature found only two cases of colon perforation associated with S. mansoni infection. To our knowledge, this is the first case of rectal perforation caused by S. haematobium described in the literature. Copyright © 2009 by The American Society of Tropical Medicine and Hygiene.
