Intestinal strongyloidiasis. A case report and review of the literature.

: A patient infected with Strongyloides stercoralis presented with hematemesis and abdominal pain mimicking peptic ulcer disease. Radiologic evaluation, however, suggested Crohn's disease of the proximal small intestine. Aspiration of intestinal fluid and a small bowel biopsy lead to a diagnosis of invasive strongyloidiasis. This case is presented and the literature reviewed to demonstrate the protean manifestation of this parasite which commonly involves the gastrointestinal tract.
