#4605 Primary mammary neuroendocrine tumour: A case report and literature review

Introduction: Primary neuroendocrine carcinomas of the breast are rare, accounting for only 2 to 5% of all breast cancers. These tumours have recently been included in the latest WHO classification of breast tumours. The diagnosis can be challenging due to its uncommon presentation and overlap with other breast pathologies.

#4218 Primary hepatic neuroendocrine tumor in a series of 8 cases

Introduction: Primary neuroendocrine (NET) tumors of the liver are extremely rare, accounting for 0.3% of all NETs; unlike metastatic neuroendocrine tumors, rarely cause carcinoid syndrome. Edmonson reported the first case in 1958. Since then, fewer than 150 cases have been reported in the literature. Before making the diagnosis of primary hepatic neuroendocrine tumor it is imperative to explore the patients, several radiological investigations can help to pinpoint the primary which is most often digestive.

#3755 Large cell neuroendocrine carcinoma of the breast

Introduction: Primary neuroendocrine breast carcinomas are rare and little-known tumors. They account for only 2 % to 5 % of breast cancers. Diagnosis is based on neuroendocrine architecture associated with the expression of neuroendocrine markers.

#3108 Challenges in primary neuroendocrine tumor identification

Introduction: ACTH secreting neuroendocrine tumors can be a pituitary adenoma, an ectopic tumor, or very rarely - pituitary carcinoma. The identification of the primary neuroendocrine tumor can be challenging or even unsuccessful.

#2691 Somatostatin Analogs in Patients with Zollinger Ellison Syndrome (ZES): An Observational Study

Introduction: Zollinger Ellison syndrome (ZES) is a rare syndrome caused by gastrin hypersecretion from a primary neuroendocrine tumor (NET), usually located within the duodenum or into the pancreas. Gastrinomas have two important treatment goal: the control of the gastrin-excess state and the control of tumor growth.
