title: Diagnostic difficulty in a case of heterotopic pancreatic tissue of the ileum.
abstract: We describe a case of heterotopic pancreatic tissue of the ileum causing acute gastrointestinal tract bleeding. It was initially clearly demonstrated as an ileal polyp preoperatively by radiologic means. Exploratory surgery was performed, and the segment of ileum containing the mass was resected. Histopathologic examination of the lesion revealed heterotopic pancreatic tissue of Heinrich type II. There was no histological evidence of acute or chronic pancreatitis, but erosion was confirmed at the tip of the mass. Even symptomatic heterotopic pancreatic tissue of the ileum may give difficult diagnostic problems. The present case is reported to show the possibility of diagnosing rare abnormalities of the ileum.
