#1168 Simultaneous Large Cell Neuroendocrine Carcinoma and Adenocarcinoma of the Stomach: A Case Report and Literature Review
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.

#67 Interest of combined chromogranin A and pancreatic polypeptide for diagnosis and follow-up of gastroenteropancreatic endocrine carcinoma
Introduction: Assessment of tumor burden changes is essential for the management of well-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEPNET). Chromogranin A (CgA) is the principal tumor marker for such tumors; however, its use to evaluate morphological tumor progression is not validated. Combined CgA and pancreatic polypeptide (PP) may increase sensitivity in the diagnosis of GEP-NET.

#558 MANECs Among Colorectal Signet Ring Cell Carcinomas
Introduction: The mixed adenoneuroendocrine carcinomas (MANEC, WHO 2010) are neoplasms with heterogeneous morphology, whose mixed nature may be difficult to recognize.

#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.

#634 Merkel Cell Carcinoma in a Nine-Year-Old Girl
Introduction: Merkel cell carcinoma (MCC) of the skin is a rare neuroendocrine tumor characterized by its rapid growth and aggressive clinical behavior. MCC is a typical tumor of older age (average age is 65 years). In children and adolescents less than 20 years of age, it is extremely rare. Information regarding MCC in childhood can be found in the literature only in the form of individual case reports. Due to the rarity of MCC in the young population, any clinical studies or treatment recommendations in these patients are missing.

#699 Ethanol Ablation in an 81-Year-Old Patient with Pancreatic Neuroendocrine Tumor (Islet Cell Tumor) and Severe Hypoglycemia – A Case Study.
Introduction: The key clinical problem in patients with islet cell tumors are persistent hypoglycemia episodes, which are particularly dangerous in the elderly since neuroglycopenia may be the cause of stroke.

#1129 Expression and Clinical Significance of Merkel Cell Polyomavirus Large T Antigen in Merkel Cell Carcinoma
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin cancer that is often associated with Merkel cell polyomavirus (MCPyV) infection. MCPyV expression and its relationship with clinical features and prognosis in MCC remain unclear.

#1864 Analysis of mTOR, CXCR4 and PD-1 Checkpoint Pathways in Merkel Cell Neuroendocrine Carcinomas: Correlations with Prognosis and Viral Status
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine tumor. Prognostic factors currently included in the reference AJCC classification are mainly clinical.

#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.
