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.
A neoplasm that usually involves blood vessels and occurs in the pancreas or may be present in the wall of the duodenum. It produces excessive amounts of gastrin, which stimulates gastric acid secretion and consequent ulcer formation.
a gastrin-releasing islet cell tumour that is associated with Zollinger-Ellison syndrome
refers to a tumor that secretes the hormone gastrin. Elevated levels of gastrin can cause severe ulcer disease and diarrhea.
Benign or malignant gastrin-secreting islet-cell tumor of the pancreas. There is an overproduction of gastric acid often resulting in an ulcer.
Tumor that develops in the pancreas or duodenum of patients with Zollinger-Ellison syndrome. Gastrinomas secrete the hormone gastrin.
a gastrin-producing neuroendocrine tumor arising in the pancreas or in adjacent tissues
a tumor usually in the pancreas or duodenum (the first segment of the small intestine) that produces excessive levels of the hormone gastrin, which stimulates the stomach to secrete acid and enzymes, causing peptic ulcers
A tumor that produces gastrin, making the stomach and duodenum more acidic.
Rare type of endocrine tumour of the pancreas which secretes (makes and releases) abnormal amounts of gastrin (a digestive hormone).
A rare tumor that actively produces the hormone gastrin. Patients with gastrinoma may present with heartburn, abdominal pain, diarrhea, and weight loss.
A Gastrinoma is a tumor that secretes gastrin.
