Intraductal oncocytic papillary neoplasms of the pancreas.
We describe the clinical and pathologic features of 11 intraductal oncocytic papillary neoplasms of the pancreas, a hitherto unrecognized tumor. The patients were six men and five women, and most of the tumors were in the head (head: body/tail = 8:3). The mean patient age was 62 (range, 39-78), and the average tumor size was 6 cm. Grossly the tumors exhibited mucin-filled cysts containing nodul...
متن کاملFDG-PET Findings of Intraductal Oncocytic Papillary Neoplasms of the Pancreas: Two Case Reports
Intraductal oncocytic papillary neoplasm (IOPN) of the pancreas is a rare pancreatic tumor. To date, there have been three case reports of IOPN which showed strong positivity on 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), raising the possibility of distinguishing IOPNs from other intraductal papillary mucinous neoplasms (IPMNs) using FDG-PET. However, all three cases had larg...
متن کاملIntraductal papillary mucinous neoplasms of the pancreas.
BACKGROUND/AIMS Intraductal papillary mucinous neoplasms (IPMNs) are neoplasms of the pancreatic duct epithelium characterized by intraductal papillary growth and thick mucin secretion. Quantities of mucin fill the main and/or branches of pancreatic ducts and cause ductal dilatation. This review encompasses IPMNs, including symptoms, diagnosis, management, and prognosis. METHODS A Pubmed data...
متن کاملIntraductal Papillary Neoplasms of the Bile Duct
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas. IPNBs display a spectrum of premalignant lesion towards invasive cholangiocarcinoma. The most common radiologic findings for IPNB are bile duc...
متن کاملIntraductal Papillary Mucinous Neoplasms: The Bologna Experience
Background In the last decades, the attention to Intraductal Papillary Mucinous Neoplasms (IPMNs) has risen due to the increase of their incidental diagnosis. The aim of the present study was to evaluate which factors influenced survival in population affected by intraductal papillary mucinous neoplasms. Methods A retrospective study on a prospective database of 357 patients observed at our Ins...
