Neuroendocrine tumors, produce excessive amounts of hormones and include carcinoid syndrome, Zollinger Ellison syndrome, VIPomas, insulinomas gastrinoma, glucaginoma and somatostatinoma, among others.
These tumors are classified according to the predominant hormone of oversecretion: insulinoma, gastrinoma, vasoactive intestinal peptide-secreting tumors (VIPoma), glucagonoma, somatostatinoma, and growth-hormone-releasing factor-secreting tumors (GRFomas).
Similarly, VIPomas, somatostatinomas, and GRFomas may also arise outside of the pancreas.
