[Pancreatic polypeptide secreting endocrine pancreas tumor associated with multiple stomach and duodenal ulcers].

A 58-year-old woman presented with multiple gastroduodenal ulcera caused by a pancreatic polypeptidoma (PPoma) without hypergastrinemia or gastrin-producing tumor cells. After curative resection of the neoplasm, the clinical symptoms disappeared and the patient has now been disease-free for 6 years. We conclude that patients with non-gastrin-producing endocrine pancreatic tumors may demonstrate the clinical features of Zollinger-Ellison syndrome and should be included in the differential diagnosis of this syndrome.
