Benign (nonmalignant) tumor of insulin secreting cells of the islets of Langerhans in the pancreas. It results in excessive insulin production and is one of the main causes of hypoglycemia. See Hypoglycemia. It is a rare disease and very difficult to diagnose because symptoms are often vague and mimic neurologic and psychiatric disorders. Treatment is usually surgical removal of the tumor. Frequent high carbohydrate meals or medication may also be used.
a noncancerous tumor of the insulin-producing cells of the pancreas; the tumor releases excess insulin into the blood, causing glucose levels to drop dangerously low
an islet cell tumour that secretes excess insulin, and may occasionally secrete other hormones, including gastrin, ACTH, and glucagon
is a type of tumor of the endocrine cells of the pancreas that makes insulin and can cause severe hypoglycemic attacks (low blood sugar).
a cancer of the beta cells of the pancreas
a clinically functional tumor that causes a characteristic syndrome due to hypersecretion of insulin
a neuroendocrine tumor deriving mainly from pancreatic islet cells that produce excessive amounts of insulin
a rare benign tumour of the insulin-producing cells of the pancreas
a rare tumor of the pancreas of dogs and cats
a tumor in the pancreas (APUD cells of the islets of Langerhans) that produces too much insulin
a tumor that occurs in the pancreas
a usually benign tumor of the insulin-secreting cells of the pancreas
A tumor of the beta cells in the pancreas. An insulinoma may cause the body to make extra insulin, leading to hypoglycemia.
Rare type of tumour of the pancreas which secretes (makes and releases) abnormal amounts of insulin.
A tumor of the beta cells in areas of the pancreas called the islets of Langerhans. Although not usually cancerous, such tumors may cause the body to make extra insulin and may lead to a blood glucose (sugar) level that is too low.
An insulinoma is a tumour of the pancreas derived from the beta cells which while retaining the ability to synthesize and secrete insulin is autonomous of the normal feedback mechanisms. Patients present with symptomatic hypoglycemia which is ameliorated by feeding. The diagnosis of an insulinoma is usually made biochemically with low blood sugar, elevated insulin, pro-insulin and C-peptide levels and confirmed by medical imaging or angiography.
