Updated morphological and immunohistochemical profile of neuroendocrine tumors developed in ovarian teratomas: A large series of a rare disease
Introduction:
Ovarian carcinoid tumors are rare, often arising within a mature teratoma. No recent reevaluation of the immunophenotype of these tumors with new markers available has been performed.

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.
