Gastrinomas are neuroendocrine tumors (NETs), usually located in the duodenum or pancreas, that secrete gastrin and cause a clinical syndrome known as<unk><unk>  syndrome (ZES). A large number of gastrinomas develop in the pancreas or duodenum, with near-equal frequency, and approximately 10% arise as primary neoplasms in lymph nodes of the pancreaticoduodenal region (gastrinoma triangle). Most gastrinomas are sporadic (75%–80%), whereas approximately 20% to 25% are associated with multiple endocrine neoplasia type 1(MEN-1). Over 50% of gastrinomas are malignant and can metastasize to regional lymph nodes and liver. One fourth of gastrinomas are related to multiple endocrine neoplasia type 1,<unk><unk><unk>  syndrome, peptic ulcer disease.
