Definitions related to insulinoma:
-
A benign tumor of the PANCREATIC BETA CELLS. Insulinoma secretes excess INSULIN resulting in HYPOGLYCEMIA.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
A type of tumor of the pancreatic beta cells that secretes excess insulin and can result in hypoglycemia.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
A usually benign tumor of insulin secreting pancreatic beta cells, associated with hypoglycemia.NICHD Pediatric TerminologyU.S. National Cancer Institute, 2021
-
An abnormal mass that grows in the beta cells of the pancreas that make insulin. Beta cell neoplasms are usually benign (not cancer). They secrete insulin and are the most common cause of low blood sugar caused by having too much insulin in the body.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
Insulinoma is the most common type of functioning pancreatic neuroendocrine tumor characterized most commonly by a solitary, small pancreatic lesion that causes hyperinsulinemic hypoglycemia.OrphaNetINSERM, 2021
-
(pancreatic insulin-producing neuroendocrine tumor) An insulin-producing neuroendocrine tumor arising from the beta cells of the pancreas. It may or may not be associated with inappropriate secretion of insulin and an associated clinical syndrome.NCI ThesaurusU.S. National Cancer Institute, 2021
-
An insulinoma is a rare pancreatic beta-cell tumor that hypersecretes insulin. The main symptom is fasting hypoglycemia. Diagnosis is by a 48- or 72-hour fast with measurement of glucose and insulin levels, followed by endoscopic ultrasound. Treatment is surgery when possible. Drugs that block insulin secretion (eg, diazoxide,...Merck & Co., Inc., 2020

Insulinomas are the most common cause of hypoglycemia resulting from endogenous hyperinsulinism. In a large single-center series of 125 patients with neuroendocrine tumors, insulinomas constituted the majority of cases (55%), followed by gastrinomas (36%), VIPomas (vasoactive intestinal polypeptide tumor) (5%), and glucagonomas (3%).WebMD, 2019
-
Insulinoma is a type of pancreatic neuroendocrine tumor (pancreatic NET), which refers to a group of rare tumors that form in the hormone -making cells of the pancreas. Insulinomas, specifically, produce too much insulin, a hormone that reduces the level of sugar in the blood by helping it move into cells. As a result, people with...National Center for Advancing Translational Sciences
