Ileocolonic schistosomiasis presenting as lymphoma.

The blood flukes of the genus Schistosome have a wide geographic distribution. Schistosoma japonicum is found in the Far East while Schistosoma mansoni is found in Africa, South America, the Middle East, and the Carribean. There are numerous other species of Schistosome; however, japonicum, mansoni, and hematobium account for the majority of human disease. Infection of the gastrointestinal tract is not uncommon in the United States. Recognition of this disease is important for appropriate medical therapy and avoidance of unnecessary surgery. A case of schistosomiasis simulating small bowel lymphoma is presented and salient features of this infection are reviewed.
