Abstract
In this presentation the gastrointestinal pancreatic endocrine tumors (ETs) are subdivided into well differentiated ETs and poorly differentiated ETs. Well differentiated ETs are subclassified into ETs with benign behavior, ETs with uncertain behavior and well differentiated endocrine carcinomas. The criteria allowing a distinction among these main types of neoplasms are listed according to the site of origin of the ETs. In addition, the main functional types of ETs of the pancreas, stomach, duodenum, jejunum, ileum, appendix and large bowel are briefly described.
