A rare disorder caused by a tumor called a gastrinoma, most often occurring in the pancreas. The tumor secretes the hormone gastrin, which causes increased production of gastric acid leading to severe recurrent ulcers of the esophagus, stomach, and the upper portions of the small intestine (the duodenum and jejunum). Gastrinomas resulting in the Zo [..]

A disorder in which tumors of the pancreatic islet cells produce large amounts of gastrin (a hormone), leading to excess acid in the stomach and, possibly, a peptic ulcer (ulcer of the stomach or the [..]

This is a condition that is caused by a gastrinoma, which is a tumor, that usually occurs in the pancreas. The hormone gastrin is secreted by this tumor, which results in an increase in the production of gastric acid. This leads to recurrent and severe ulcers forming in the upper parts of the small intestine (the duodenum as well as the jejunum), t [..]

A syndrome that is characterized by the triad of severe PEPTIC ULCER, hypersecretion of GASTRIC ACID, and GASTRIN-producing tumors of the PANCREAS or other tissue (GASTRINOMA). This syndrome may be sp [..]
