[2] It is a disease which is congenital[2] and is also known as heterotopic, accessory, or aberrant pancreas.

[1] Heterotopic pancreas is commonly recognized as an incidental finding on imaging studies performed for an unrelated reason.

Ectopic pancreatic tissue may occur anywhere in the abdominal cavity, though more than 90 percent are found in the stomach, duodenum, or jejunum.

[1] Rarely, pancreatic heterotopic tissue may be found in the colon, spleen or liver.

Confirmation of the diagnosis requires tissue sampling, via biopsy or surgical resection.
