Colonic schistosomiasis and associated cecal neuroma

Abstract

Schistosomiasis remains a major health threat in many resource-poor countries and is being seen with increasing frequency in developed countries among immigrants and tourists who have a history of freshwater exposure in endemic areas. We report a case of a 56-year-old male with no significant past medical history, who presented for a routine screening colonoscopy, which revealed two polyps in the cecum, and multiple petechiae in the rectum. Histologic evaluation showed presence of Schistosoma mansoni eggs. One of the polyps, where eggs were also present, was diagnosed as neuroma/Schwann cell hamartoma. This is the first reported case where colonic schistosomiasis is associated with cecal neuroma.
