Zollinger-Ellison syndrome
Zollinger-Ellison syndrome is a disease process associated with the development of ulcers due to over secretion of Gastrin.
Gastrinomas are tumors characterized by secretions of large amounts of gastrin, a hormone that increases the amount of acid released by the stomach.
If the gastrinoma is removed with surgery and there is no evidence of spread to other organs, the person may be cured. These people can often lead a normal life free of ulcer symptoms.

How is Zollinger-Ellison Syndrome Diagnosed?
In Zollinger-Ellison syndrome, tumors called gastrinomas produce large amounts of gastrin. This is a hormone that increases the amount of stomach acid. When a large amount of this substance is produced, too much stomach acid is made.
Gastrinoma: A tumor that forms in cells that make gastrin. Gastrin is a hormone that causes the stomach to release an acid that helps digest food. Both gastrin and stomach acid are increased by gastrinomas.

gastrinoma - a tumor that secretes above average levels of gastrin, a hormone that stimulates the stomach to secrete acids and enzymes. Gastrinoma can cause peptic ulcers.
Gastrinomas produce too much of a hormone called gastrin. Gastrin stimulates acid production by the stomach and too much of this hormone leads to over production of gastric acid which leads to very severe gastric and duodenal ulceration, ...
Gastrinoma. A gastrinoma describes an islet cell tumor that produces a large amount of gastrin, a hormone that causes an excess amount of acid to be made in the stomach. This results in a condition called Zollinger-Ellison syndrome.
Gastrinoma
A rare type of endocrine tumour of the pancreas. It makes and releases (secretes) abnormal amounts of a digestive hormone called gastrin.

gastrinoma A tumor that causes overproduction of gastric acid. It usually occurs in the islet cells of the pancreas but may also occur in the esophagus, stomach, spleen or lymph nodes.
gastritis Inflammation of the lining of the stomach.
Gastrinomas may also occur in the stomach, duodenum, spleen and regional lymph nodes.
Treatment includes the use of H2 antagonists (for example cimetidine, ranitidine). Surgical excision of the tumour is curative in approximately 25% of patients.
Gastrinomas occur as single tumors or small multiple tumors. Not only can these tumors lead to ulcers, they can also be cancerous (up to 66% malignant) and spread to the nearby lymph nodes or liver.

Zollinger-ellison syndrome A group of symptoms that occur when a tumor called a gastrinoma forms in the pancreas. The tumor, which may cause cancer, releases large amounts of the hormone gastrin.

In this condition, tumors in the pancreas and duodenum (called gastrinomas) produce excessive amounts of gastrin, a hormone that stimulates gastric acid secretion.
In the pancreas: the different types of pancreatic NETs are named according to the hormone they produce. For example, insulinomas produce too much insulin and gastrinomas produce too much gastrin (a hormone that stimulates stomach acid secretion).

Often occurs in the pancreas, prostate and ampulla of Vater. As the tumor can arise in a variety of parts of the body, the symptoms will depend on the location of the tumor and the amount and type of hormone secreted e.g. insulinoma, gastrinoma.
