[Small-intestine tumor with ectopic pancreas tissue and acute pancreatitis].

Ectopic pancreas tissue is usually a rare and incidental finding during surgery. Reports of discovery during surgery vary between 0.17% and 0.83%. We report on an 86-year-old woman admitted to the surgical ward with abdominal pain. Due to suspicion of a perforated gastric ulcer, an exploratory laparatomy was performed. An 8 x 5 cm tumor was found in the ileum 10 cm from the ligament of Treitz. Microscopic examination revealed, surprisingly, pancreatic tissue in the submucosa of the ileum with inflammation and transmural perforation. There was no indication of malignancy.
