Ectopic pancreas: a very unusual intestinal mass.

The ectopic pancreas is a rare entity, characterized by the presence of pancreatic islets in different locations of the gastrointestinal tract. Its clinical manifestations are nonspecific and it is often diagnosed incidentally in imaging tests or intraoperatively. Its management is controversial, since its malignancy is infrequent; however, its resection is recommended in the case of a casual intraoperative finding to establish the definitive histological diagnosis. Therefore, the ectopic pancreas should be included in the differential diagnosis of intestinal masses.
