Pancreatic neuroendocrine neoplasms (pannens) are usually classified as functional pannens and nonfunctional pannens. Patients with functional pannens display symptoms corresponding to neuroendocrine hormones excessively released by these neoplasms. The most frequent functional pannens are insulinoma followed by glucagonoma, somatostatinoma, gastrinoma, and vipoma.
