Pancreatic adenocarcinoma in duodenal ectopic pancreas: a case report and review of the literature.
Ectopic pancreas is defined as pancreatic tissue outside the normal location without connection to the normal pancreas. It occurs throughout the gastrointestinal tract, most commonly in the stomach (25-60%), followed by the duodenum (25-35%) and jejunum (16%). It may develop the same pathological changes of a normal pancreas such as acute pancreatitis and cyst formation. Malignant degeneration rarely occurs. We present a case of heterotopic pancreatic adenocarcinoma localized in the duodenal bulb presenting with symptoms of gastric obstruction.
