Abstract
Neuroendocrine tumor (NET) arises at multiple sites in the gastrointestinal (GI) tract; in fact GI tract is among the most common sites for NET in human. GI NET may present as well-differentiated neoplasms, further classified in grade 1 and grade 2 depending on the presence or absence of necrosis and on mitotic activity; or they may present as grade 3 neuroendocrine carcinomas which include large cell and small cell carcinoma. This chapter will be focusing on differentiating neuroendocrine neoplasms from other types of morphologically similar neoplasms encountered in daily practice, predominantly those encountered in the GI tract.
