Neuroendocrine tumors are rare and develop most commonly in the lungs, appendix, small intestine (duodenum), rectum and pancreas.
Glucagonoma (Neuroendocrine Tumor)
Overview
Glucagonoma is a rare neuroendocrine tumor that originates in the alpha2 cells of the pancreas.
Alternate Names : Islet cell tumors, Islet of Langerhans tumor, Neuroendocrine tumors
Definition
A pancreatic islet cell tumor is an uncommon tumor of the pancreas that arises from a type of cell called the islet cell in the pancreas.
neuroendocrine tumor A tumor derived from cells that release a hormone in response to a signal from the nervous system.

Neuroendocrine tumors may associated with the following conditions inherited genetically:
multiple endocrine neoplasia (MEN) types 1 and 2
von Hippel-Lindau (VHL) disease ...
Some neuroendocrine tumors in the pancreas include the following - they may be benign (noncancerous) or malignant (cancerous):
Insulinoma - a rare pancreatic tumor that secretes insulin, the hormone that lowers glucose levels in the blood.
Definition Neuroendocrine tumor refers to the type of cell that a tumor grows from rather than where that tumor is located.

Carcinoid tumors are neuroendocrine tumors composed of uniform, round, or polygonal cells. Immunohistochemistry reveals the presence of neuron-specific enolase (NSE) and chromogranin. Electron microscopy shows neurosecretory granules.
MIBG (metaiodobenzylguanidine) scan: A procedure used to find neuroendocrine tumors, such as neuroblastomas and pheochromocytomas. A small amount of radioactive material called MIBG is injected into a vein and travels through the bloodstream.

A now universally approved (though costly) way of finding carcinoid tumors, as well as other neuroendocrine tumors, is the OctreoScan.
Chromogranin A is used as a marker for carcinoid and other neuroendocrine tumors. Sensitivity and specificity for neuroendocrine tumors can exceed 75%, and diagnostic accuracy is higher with diffuse than with localized tumors.
Endrocrine tumors are often grouped as neuroendocrine tumors or islet cell tumors. The subtypes of islet cell tumors are named according to the type of hormone-making cell from which they originate.

Islet cell tumors, also known as neuroendocrine tumors, are less common and more likely to be benign. Normally, the pancreas' islet cells produce insulin and other hormones. Islet cell tumors can also produce these hormones.

The common hormones released are serotonin, bradykinin (a molecule produced by enzymes at the site of an injury and then binds to receptors to cause pain), histamine, and chromogranin A (a general marker for neuroendocrine tumors).
