#3269 A carcinoid heart revealing a neuroendocrine tumor

Introduction: Carcinoid heart disease can occur in patients with a carcinoid tumor and is defined by the presence of right organic valve disease. These are mainly patients with carcinoid syndrome, often with delayed diagnosis. The difficulty of this pathology is due to its rarity and the fact that it involves several medical and surgical specialties.

#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.

#2922 Clinicopathological Characteristics of Borderline Pulmonary Neuroendocrine Neoplasms

Introduction: According to the WHO 2015 classification pulmonary neuroendocrine neoplasms (NENs) are subdivided in carcinoids and neuroendocrine carcinoma (small cell lung carcinoma and large cell neuroendocrine carcinoma (LCNEC)), based on the presence of necrosis and mitotic index (MI). However, in some NENs a discrepancy is observed between grade of differentiation and proliferation rate.

#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.
