#2764 Cystic Pancreatic Neuroendocrine Tumors. Can We Diagnose Them Preoperatively?

Introduction: Pancreatic neueroendocrine tumors rarely undergo cystic changes but they are often misdiagnosed as pancreatic mucinous cystadenoma, mucinous cystadenocarcinoma, serous cystadenoma, and solid and cystic papillary tumors, or pseudocyst.

#991 Primary Neuroendocrine Tumor of Extrahepatic Bile Duct

Introduction: Biliary tract primary malignant tumors are rare neoplasms. Eighty-five per cent are cholangiocarcinomas, being in exceptional cases a neuroendocrine tumor. The absence of clinical suspiction involves a difficult preoperative diagnosis.

#859 Pancreatic Neuroendocrine Tumors (PNETs): Role of Endoscopic UltraSound-Fine Needle Aspiration (EUS-FNA) and Accuracy of Ki-67 Measurement on Cytological Specimens

Introduction: The role of EUS-FNA in preoperative diagnosis and grading of pNETs is well-established, but it is unclear how Ki-67 expression on cytological specimens obtained by EUS-FNA reflects the value found on surgical specimens.

#740 Heterotopic Pancreatic Tissue Located in the Subserosa of the Jejunum: A Case Report

Introduction: Ectopic pancreas is defined as pancreatic tissue in an abnormal location with no ductal, anatomical, neuronal or vascular communication with the main body of the pancreas. The incidence of heterotopic pancreas in autopsy studies is approximately 0.6 - 15%, while the clinical incidence is 1 in 500 laparotomies. Ectopic pancreatic tissue can be present anywhere along the gastrointestinal tract.

#569 Lack of Accuracy of Circulating Chromogranin A in the Preoperative Diagnosis of Lung Neuroendocrine Tumors

Introduction: While the role of the circulating neuroendocrine (NE) marker Chromogranin A (CgA) in the clinical management of GEP NET has been extensively discussed, the same role in thoracic NE tumors (TNET) remains to be better clarified.
