#931 A Case of Adrenal Pheochromocytoma Rupture Treated with Transarterial Embolization (TAE)
Introduction: Spontaneous hemorrhage within a pheochromocytoma resulting in capsular rupture and hemorrhage is a rare condition, but also catastrophic and highly lethal event. An emergent operation for pehochromocytoma rupture is higher mortality than elective operation, and misdiagnosis and failure to control the hemorrhage lead directly to 100% mortality.

#984 Superior Mesenteric Vein Stenting for Management of Complications of Mesenteric Desmoplasia in Midgut Neuroendocrine Tumors
Introduction: Mesenteric fibrosis is a cause of morbidity and mortality in patients with midgut neuroendocrine tumors (mNETs). It may cause occlusion of the superior mesenteric vein (SMV), which can be associated with development ascites and mesenteric and small bowel varices (SBVs) leading to occult gastrointestinal (GI) bleeding.

#1738 Sinonasal Neuroendocrine Small Blue Cell Tumour (SNBCT) Presenting with Bone Marrow Failure – A Very Rare Diagnostic and Therapeutic Challenge
Introduction: A 75 year old female presented with rapid onset right neck swelling and nasal bleeding. CT showed an infiltrative soft tissue mass involving the entire right nasal cavity and a lymph node mass in the right neck.

#36 A monocentric analysis of patients with pulmonary neuroendocrine tumors over 15 years: long term survival and life quality dependent from histological subtypes and surgical management
Introduction: Pulmonary neuroendocrine tumors substantially differ from epithelial tumors in terms of tumor biology and prognosis. In specialized interdisciplinary centers, a broad therapeutical armentarium can be used to achieve optimal treatment.

#101 Chronic Complications of Peptide Receptor Radionuclide Therapy (PRRT)- A Single Center Experience
Introduction: In the last decade, a new treatment modality, peptide receptor radionuclide therapy (PPRT), has been introduced for gastroenteropancreatic neuroendocrine tumor (GEPNET) patients with non-resectable or progressive disease. PRRT has been associated with several complications, including bone marrow suppression, renal toxicity and hepatic damage.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.

#122 Molecular genetic findings in gastric carcinoid suggest possible neurofibromin/Ras pathway involvement in carcinoid pathogenesis
Introduction: The molecular pathogenesis of gastrointestinal carcinoid tumours is poorly understood. We have been undertaking molecular genetic investigations of a young woman with neurofibromatosis type 1 (NF1) in whom a gastric carcinoid tumor was detected following an episode of gastrointestinal bleeding. She was otherwise relatively mildly affected by NF1. In NF1, gastric carcinoids have been found previously only in patients with other predisposing factors, which were absent in this patient.

#649 Poorly Differentiated Rectal Neuroendocrine Tumors: A Report of Three Cases
Introduction: Rectal neuroendocrine tumors (NETs) are rarely seen, representing only 1% to 2% of all rectal tumors, and 17% gastrointestinal NETs. They are classified by site of tumor origin and by degree of differentiation.
