Neuroendocrine tumors arise from cells that release hormones in response to neural stimuli. They are more formally known as multiple endocrine neoplasmas (MENs) and usually arise in the pancreatic islet cells and the pituitary gland. Neuroendocrine tumors are marked by hyperfunctioning of the anterior pituitary gland, pancreatic islets and parathryroid glands. They also include medullary thyroid carcinomas (MTCs) and pheochromocytomas. The following steps will show how to diagnose neuroendocrine tumors. Observe the initial symptoms of MENs. The most common symptom is hyperparathyroidism, but some patients may present with Zollinger-Ellison syndrome first. The gastrinoma may cause abdominal pain and diarrhea. Expect the clinical picture to be dependent on which hormones are being secreted in excess. Hyperparathyroidism is associated with bone abnormalities and mild hypercalcemia, a glucagonoma causes hyperglycemia and an insulinoma causes hypoglycemia. A pituitary tumor can cause headac
