Definition

Neuroendocrine neoplasms of the digestive system (Rindi et al. 2010), namely, in the stomach (g-NENs), include (1) Neuroendocrine tumors (NETs) – carcinoids and well-differentiated endocrine tumors/carcinomas; (2) Neuroendocrine carcinomas (NECs): poorly differentiated endocrine carcinomas, high-grade neuroendocrine carcinomas, small-cell and large-cell endocrine carcinomas; and (3) Mixed adenoneuroendocrine carcinomas (MANECs) (Solcia et al. 2010); there are also hyperplastic and preneoplastic neuroendocrine lesions. Precursor neuroendocrine lesions of the stomach that occur in hypergastrinemic conditions (autoimmune chronic atrophic gastritis, multiple endocrine neoplasia type 1, and Zollinger-Ellison syndrome) include (a) enterochromaffin-like cell (ECL) hyperplasia (linear, micronodular <150 μm, and adenomatoid) and (b) dysplasia(enlarged micronodules...
