On histological examination, mitoses were easily found: 3/10 fields and there were multiple foci of necrosis. On immunohistochemistry, the tumor cells were positive for CD31 and negative for: cytokeratine AE1-AE3, CK7,CK5-6,CK20,EMA,P63,PSA,CDX2,PSO4S, chromogranine A,PS100,CD34,Actine, Desmine, Caldesmone, CD117,DOG1.

A 62-year-old woman diagnosed with a pancreatic neuroendocrine tumor (NET) underwent surgery in 2004 and was reoperated in 2009 for recurrence in the greater curvature of the stomach. Theposterior clinical and radiological controlswerenegative until 2011. InMarch 2011 a somatostatin receptor scintigraphy with 99mTcEDDA/HYNIC-TOC was performed to rule out new recurrence which was suspected due t...

neuroendocrine cells are of the peptide and amine secreting cells and because of endodermal origin, exist in respiratory and gastrointestinal system. the report confirms the presence of a tumor using immunohistochemical methods. a hepatic mass was detected in a 10-year-old male mixed–breed dog which was referred with clinical history of frequent vomiting, anorexia, lethargy and syncope. biochem...

Résumé Les tumeurs neuroendocrines thymiques (TNET) sont rares, de pronostic mal connu. L'objectif est de rapporter un cas de TNET et discuter la difficulté diagnostique et thérapeutique en milieu à faibles ressources. Un homme de 60 ans présentait une douleur thoracique, une toux grasse et un amaigrissement récent. Le scanner thoracique révélait une masse tissulaire médiastinale antérieure. L'...

Rare cases of carcinoid syndromes can develop from either gastrointestinal neuroendocrine tumors (NETs) without liver metastasis or large retroperitoneal involvement. We report a case patient with isolated flushing highly suggestive syndrome caused by an ileal NET adjacent lymph node metastases but no metastases. The final diagnose was delayed for this due to combination misleading clinical pre...

INTRODUCTION Prostatic gland basal cell proliferations exhibit morphological continuum ranging from basal cell hyperplasia to basal cell carcinoma. In the following report, we described clinical features, morphological spectrum, neuroendocrine differentiation and histogenesis of prostatic gland basal cell carcinoma in our patient. CASE REPORT Hematoxylin-eosin (HE), Alcian blu-periodic acid s...

Résumé Les neurocytomes centraux sont définis comme étant des néoplasmes composés de cellules rondes, uniformes, ayant un profil immunophénotypique neuronal et un index de prolifération bas. Elles représentent 0,5% des tumeurs intracrâniennes. Elles sont habituellement situées à proximité du foramen de Monro et peuvent être à l’origine d’une hydrocéphalie obstructive. Nous rapportons 12 observa...
