Zollinger-Ellison syndrome is a rare disorder that arises from tumors and ulcers in the digestive system. One or more tumors form in the pancreas or duodenum (the upper part of the small intestine). Not only can these tumors lead to ulcers, they can also be cancerous, and spread to the nearby lymph nodes or liver.
About one-quarter of people with Zollinger-Ellison syndrome have a genetic disorder called multiple endocrine neoplasia type 1 (MEN 1). People with MEN 1 may have additional endocrine tumors in the brain and neck.
