Abstract
Ectopic pancreas (EP) is defined as the presence of pancreatic tissue outside the pancreas with no anatomical connection to the pancreas. It is also known as pancreatic heterotopia, accessory pancreas, aberrant pancreas, or pancreatic rest. The first case of EP was described in 1727 when pancreatic tissue was identified in the ileal diverticulum. Abdominal pain and lower gastrointestinal bleeding are the most common symptoms. On histopathological examination, EP can be classified into four subtypes. Once identified and diagnosed, the treatment is surgical resection and the post-operative course is asymptomatic in most cases. We describe a rare case of EP, which was discovered on the CT scan of the abdomen as a jejunal mass and successfully treated with surgical resection. We have also described the possible role of chromogranin A for diagnosing EP cases and for post-operative follow-up.
