#3769 Adrenal neuroendocrine tumors in Oran – Epidemiology and survival

Introduction: Pheochromocytomas (PCC) are rare neuroendocrine tumors with a prevalence of 1/10000 in the general population. They are sporadic in 80% of cases, family forms are found in 10 to 20% of cases. PCCs represent 60% of multiple endocrine neoplasia type 2. They occur at any age with a peak between 30 and 50 years old. The clinical symptomatology dominated by arterial hypertension is linked to the hypersecretion of catecholamines. Metastases are common in the liver, bone or lung. The 5-year survival of malignant pheochromocytomas is less than 50%.

#3306 Secondary debulking of renal neuroendocrine tumor

Introduction: We presented a case of 54-year-old woman with anamnesis of left nefrectomy due to tumor of left kidney in august 2006. Histology showed well-differentiated neuroendocrine tumor of kidney (renal carcinoid tumor). MAI (mitotic activity index) were less then 1mf/10HPF. Imunohostechemistry examination showed positive of cytokeratins, chromogranin A, synaptofyzin. One metastatic lymph node was captured. Final stage of tumor was T1N1Mx. Patient was regularly followed in oncological ambulance.
