Accessory Pancreas

A rare asymptomatic embryopathy characterized by the presence of pancreatic tissue in other sites of the body such as the splenic pedicle, gonadic pedicles, intestinal mesentery, duodenum wall, upper jejunum, or, more rarely, the gastric wall, ileum, gallbladder or spleen.

Epidemiology

Prevalence is unknown and only a few cases have been reported in the literature so far.

Etiology

The anomaly is caused by migration of pancreatic cells during embryogenesis.
