Oncocytic Intraductal Papillary Mucinous Neoplasms of the Pancreas

Pancreas, 2016
To evaluate and correlate computed tomography/magnetic resonance findings and histopathologic features of oncocytic intraductal papillary mucinous neoplasms (O-IPMNs).Computed tomography/magnetic resonance examinations and resection specimens of 16 O-IPMNs were retrospectively reviewed.

Intraductal oncocytic papillary neoplasm of the extrahepatic bile duct: report of a case

Surgery Today, 2012
We report a rare case of an intraductal oncocytic papillary neoplasm (IOPN) of the extrahepatic bile duct. A 66-year-old man was admitted to our hospital for investigation of right-sided back pain. Ultrasonography, computed tomography and magnetic resonance imaging showed a papillary lesion, 3 cm in diameter, in the middle bile duct, invaginating into ...

Intraductal Oncocytic Papillary Neoplasm of the Extrahepatic Biliary Tree: First Report

The American Surgeon, 2004
Tumors with oncocytic differentiation may occur in a variety of organs, but are extremely rare in the biliary system. Intraductal oncocytic papillary neoplasms (IOPNs) were first described in the pancreas to differentiate a rare subset of pancreatic neoplasm from the intraductal papillary mucinous neoplasms (IPMNs).

Cross-Sectional Imaging Characteristics of Pancreatic Intraductal Oncocytic Papillary Neoplasms

Journal of Computer Assisted Tomography
Purpose Pancreatic intraductal oncocytic papillary neoplasms (IOPN) are rare precursors to pancreatic ductal adenocarcinoma. We report cross-sectional computed tomography and magnetic resonance imaging (where available) findings of pancreatic IOPNs. Materials and Methods Consecutive

Genetic Analysis of Invasive Carcinoma Arising in Intraductal Oncocytic Papillary Neoplasm of the Pancreas

The American Journal of Surgical Pathology, 2002
A case of intraductal oncocytic papillary neoplasm of the pancreas, with the rare progression to invasive carcinoma, is described. The intraductal oncocytic papillary neoplasm component had the features typical of this entity, with stratified layers of oncocytic cuboidal tumor cells growing in papillary and pseudopapillary arrangements within dilated ...

Pancreatic tumors with cystic dilatation of the ducts: intraductal papillary mucinous neoplasms and intraductal oncocytic papillary neoplasms.

Seminars in diagnostic pathology, 2000
Intraductal papillary mucinous neoplasms (IPMNs) and intraductal oncocytic papillary neoplasms (IOPNs) are the 2 types of intraductal neoplasms of the pancreas that may appear cystic because of dilatation of the ducts. Both are characterized by intraductal proliferation of mucinous cells usually arranged in papillary patterns.
