#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report
Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.

#1592 Primary Neuroendocrine Carcinoma of the Breast: A Diagnostic Approach to the Special Type of Breast Malignancy
Introduction: WHO classification from 2003 defines primary neuroendocrine carcinomas (NEC) of the breast as a group of tumors with expression of neuroendocrine markers in more than 50% of tumor cells. In the current WHO classification this category is renamed to “carcinomas with neuroendocrine features” without defined clear-cut of the percentage of tumor cells positive for neuroendocrine markers.

#2123 Large Cell Neuroendocrine Carcinoma (LCNEC) Associated with a Dysplastic Sessile Serrated Lesion (SSL) and Deficient Mismatch Repair (MMR) Protein: A Case Report.
Introduction: Colorectal poorly differentiated neuroendocrine carcinomas (NECs) are rare, but extremely aggressive. The mechanisms of their carcinogenesis and aggressiveness are still largely unknown. Recently Nobuyoshi Takizawa showed that the molecular features of colorectal NECs are similar to those of adenocarcinoma and not to those of NETs and they were more evident in small cell NECs than in large cell NECs. This is supported by combined cases with conventional adenoma/adenocarcinoma and NECs. Stelow et al showed that DNA mismatch repair proteins were intact in 14/15 colorectal small cell NECs. Two cases of LCNECs arising from SSL have been reported so far in the literature.

#2250 Treatment Outcomes of Patients with Mixed Neuroendocrine Non-Neuroendocrine Neoplasms (MiNEN)
Introduction: Mixed neuroendocrine non-neuroendocrine neoplasms (MiNEN) have been newly defined in the WHO 2017 classification. They are rare tumors, commonly treated in analogy to their non-neuroendocrine (nNE) or neuroendocrine (NE) component without systematic data regarding the optimal therapeutic strategy.

#2133 Clinicopathological Features of the High Grade Pancreatic Neuroendocrine Neoplasms
Introduction: The high grade pancreatic neuroendocrine neoplasms (PanNENs) include well-differentiated tumors (WD-NETs) with elevated proliferation and poorly differentiated carcinomas (PD-NECs).

#685 A Small Mixed Adenocarcinoma and Neuroendocrine Tumor of the Duodenum with Multiple Liver Metastases
Introduction: Mixed adenocarcinoma and neuroendocrine cancers (MANECs) are rare specific type of tumors that are composed of two histologic components: a neuroendocrine carcinoma and an adenocarcinoma. There are only a few reports regarding MANEC of the stomach, colon and rectum in the literature.

#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.
