#1122 Clinicopathological Characteristics and Long Term Survival Analysis of Pancreatic Neuroendocrine Incidentalomas: An Experience of 39 Cases from a Single Chinese Institute
Introduction: Pancreatic incidentaloma was found by coincidence without specific presentation like pancreatogenic abdominal pain,palpable mass,obstructive jaundice and endocrine symptoms.The characteristics and prognosis of the tumor were rarely discussed.

#59 Incidence and clinical significance of adrenal masses in patients with gastrenteropancreatic neuroendocrine tumors
Introduction: The widespread application of modern imaging modalities, mainly computerized tomography (CT) and magnetic resonance imaging (MRI), has revealed a 2-3% incidence of inadvertently discovered adrenal masses, the majority of which are non-functioning benign adrenal adenomas. In the presence of a known malignancy, such lesions have a more than 30% incidence of being metastases. As patients with gastrenteropancreatic neuroendocrine tumors (GEP-NETS) have mainly well-differentiated and slow-growing tumors and are subject to routine abdominal imaging for disease staging or during follow-up, it is important to study the incidence and significance of such lesions based on the recently introduced TNM classification system.

#1866 NET – Incidental Findings: Small, Silent and Innocent?
Introduction: Neuroendocrine tumours (NETs) are rare neoplasms, with an overall incidence of 2 cases per 100,000 individuals per year. This number is increasing due to improved diagnosis, classification and higher imaging sensitivity, which lead to discovering of small and clinically insignificant NETs.

#2185 Nonfunctional Pancreatic Neuroendocrine Tumor (NF PNET) Imaging and Evaluation Using 18F-FDG and 68Ga- DOTANOC-PET/CT: Initial Data of a Prospective Study
Introduction: Predicting aggressive behavior of NF PNET still remains controversial. It is known that lymph node metastases are rare but possible also on small (1-2 cm) NF-PNET. Positive 18F-FDG-PET/CT avidity is associated with poor prognosis in NETs.

#2278 Incidental Histological Diagnosis of Small Pancreatic Neuroendocrine Tumors: Are We Underestimating Their Incidence?
Introduction: The annual incidence of pancreatic neuroendocrine tumours (PanNET) has been estimated to be around 0.8/100,000 inhabitants.

#1209 Pancreatic Neuroendocrine Incidentalomas: When is Surgery in the Patient’s Best Interests?
Introduction: Small PNETs, many of which are diagnosed incidentally, pose a management dilemma. Whilst resection offers curative outcomes, the risks of surgery have led many to adopt surveillance strategies. 2cm is often used as a threshold for malignancy, but reports suggest that this value may not be valid.

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.

#145 Paragangliomas: a series of five cases
Introduction: Paraganglioma is a rare extraadrenal neuroendocrine tumor, composed of chromaffin cells and arising from the neural crest. The head, neck, and retroperitoneum are the most common sites for paraganglioma.

#511 Intrapancreatic Accessory Spleen (IPAS) Misdiagnosed as Nonfunctioning Pancreatic Neuroendocrine Tumor (PNET): A Case Report and Characterization of a Syndrome Based on Systematic Review of the Literature
Introduction: Management of pancreatic incidentalomas(PI) is challenging due to high risk of malignancy and limitations in prediction of their histology and biological behavior. IPAS is one of such lesions and is often misdiagnosed as a PNET.
