#2835 Primary Hepatic Neuroendocrine Carcinoma: Case Report and Literature Review
Introduction: Primary hepatic neuroendocrine carcinoma (PHNEC) is an extremely rare neuroendocrine carcinoma (NEC) that originate from the liver. The diagnosis of PHNEC remains challenging because of its rarity, and its lack of unique clinical features. Available treatment options for PHNEC include surgical resection of the liver tumor(s), radiotherapy, liver transplant, transcatheter arterial chemoembolization (TACE), and administration of somatostatin analogues.

#3035 Large-Cell Neuroendocrine Carcinoma of the Lung in Elderly Patient: Case Report and Review of Literature
Introduction: Lung neuroendocrine tumors account for less than 25% of lung cancers.Which is a rare malignant tumor with an aggressive profile has often already affected lymph nodes at presentation and it is de novo metastatic in nearly 40% of cases.

#2853 Succinate Dehydrogenase B (SDHB) Immunohistochemical Expression in Pancreatic Neuroendocrine Tumours and Correlation with Somatostatin Receptor Immunohistochemistry
Introduction: The established category of succinate dehydrogenase (SDH) deficient neoplasms includes several endocrine tumours with recent evidence that pancreatic neuroendocrine tumours (PNETs) could be included in this tumour group. The SDH complex is composed of four subunits (A-D) but loss of immunohistochemical (IHC) expression for SDHB indicates bi-allelic inactivation of any SDH component and is used as a marker for syndromic disease.

#2689 Correlation between Immunohistochemical Markers Expression and Lymph Node Metastasis in Gastroenteropancreatic Neuroendocrine Neoplasms: A Nation-Wide 10-Year Retrospective Clinical Epidemiological Study in China
Introduction: Previous research on the correlation between different pathological features and the development of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) is rare in China.

#2812 SILVELUL Project: Development of an New Potential Predictive Immunohistochemical Score (SPI) in Patients (pts) with Pancreatic Neuroendocrine Tumors (PanNET) Treated with CAPTEM or Everolimus
Introduction: Previously our group showed the potential use of a score based on MGMT, NDRG-1 and PHLDA-3 immunohistochemistry (IHC) expression as predictor of outcome in operated PanNET (Viúdez et al. Oncotarget 2016).

#2831 Immunohistochemical Profile of Digestive Neuroendocrine Neoplasms: A Retrospective Analysis in a Single Algerian Institution
Introduction: Neuroendocrine Noplasms (NEN) are rare tumours, but their incidence is clearly increasing in our country due to the improvement of diagnostic means, in particular the generalization of immunohistochemical techniques. The digestive location represents more than 70% of the cases. The anatomopathological study enables to classify the NEN in different prognostic grades according to the degree of differentiation, mitotic index and Ki67.

#2832 Lymph Node Merkel Cell Carcinoma without Primary: Long Term Survival
Introduction: Merkel cell carcinoma (MCC) is a rare aggressive cutaneous neuroendocrine carcinoma with a high rate of metastasis. Approximately 5% of MCC are found in the lymph nodes (LNs) without a primary tumor on the skin.

#2945 Misdiagnosis of Pancreatic Neuroendocrine Carcinoma - A Potential Threat
Introduction: Pancreatic neuroendocrine tumors (PNETs) are a rare clinical entity.Very less data is available in Pakistan on PNETs.Common metastatic sites are liver, lung and brain Reports involving metastasis to breast are almost negligible.

#2981 The Distance from Pathology to Molecular Imaging: SSTR Expression Comparison in 100 Gastroenteropancreatic Neuroendocrine Neoplasms
Introduction: Somatostatin receptor (SSTR) overexpression is a unique feature of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs), which establish the basis for both diagnosis and therapy. SSTR status can be evaluated by immunohistochemical staining (IHC) and 68Ga-DOTATATE PET/CT.
