Ectopic pancreatic tissues are rare anomalies and are usually submucosal lesions most commonly located in the stomach and proximal small intestine. The authors herein describe an uncommon case of an extramural duodenal ectopic pancreatic tissue, which was misinterpreted as an exophytic pancreatic tumour on imaging examination. Laparoscopy was undertaken because of unresolved symptoms, and the ectopic pancreatic tissue was located beyond the duodenal submucosal and muscular layer on pathologic examination.
