Neuroendocrine Carcinoma (NEC) and Composite Exocrine-Neuroendocrine Carcinoma (CENEC) of the Stomach: A Clinicopathological Review of 58 Cases Abstract #443

Introduction: NEC of the stomach is an uncommon tumor accounting for 0.5% of all gastric carcinomas and about 6% of gastric NETs. CENEC contain both areas of NEC and conventional carcinoma. The histological diagnosis is difficult.
Aim(s): To evaluate clinicopathological features and prognosis of NEC.
Materials and methods: The retrospective analysis of the pathologic reports from 1999 to 2011 has identified 58 cases of gastric NEC/CENEC. All samples have been newly examined by one pathologist using immunohistochemical (IHC) staining. CENECs with at least 30% of NE component were included. In total, 41 NEC and 17 CENEC were studied.

#867 Mixed Adenoneuroendocrine Carcinoma (MANECs): A Rare and Challenging Subgroup of Neuroendocrine Neoplasia
Introduction: Mixed Adenoneuroendocrine Carcinomas (MANECs) are rare entities in which at least 30% of neoplastic cells are neuroendocrine in nature (WHO 2010 classification). They result either from two independent lesions that merge together or are unique lesions with different cell populations intermingled.

Introduction: Large cell neuroendocrine carcinoma (LCNEC) of the stomach is rare. Gastric NEC occasionally has another component, such as adenocarcinoma, in the same tumor. However, the concurrent occurrence of LCNEC and adenocarcinoma at different sites in the stomach is extremely rare.
