#2941 Mixed Urothelial and Neuroendocrine Carcinoma of the Urinary Bladder: Case Report and Literature Review

Introduction: Neuroendocrine tumors (NETs) comprise <1% of all bladder tumors,characterized by poor prognosis. These tumors may be either pure or impure, intermixed with urothelial carcinoma. There is currently no therapeutic consensus. We report the case of primary impure neuroendocrine carcinoma (NEC).

#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.

#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.

#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.
