A case of primary intrahepatic gastrinoma.

Gastrinoma is an uncommon but important cause of peptic ulcer disease. These tumors are most commonly located in the duodenum or pancreas. We present a case of a primary intrahepatic gastrinoma. Only 20 such cases have been previously reported in the literature. Metastatic hepatic gastrinomas are much more common, but it is important to differentiate between a primary and metastatic lesion because of the worse prognosis associated with a metastatic lesion.
