Strongyloidiasis. An unusual cause of colonic pseudopolyposis and gastrointestinal bleeding.

This report describes a recent case in which colonoscopy of a patient with the presenting complaint of rectal bleeding revealed the right colon to be carpeted with 50-100 pseudopolyps, each 3-4 mm in diameter. Biopsy specimens taken during colonoscopy revealed the presence of Strongyloides stercoralis in the bowel wall. This diagnosis should be considered in any patient with gastrointestinal complaints and a history of travel to an endemic area.
