Metastasis of Pancreatic Intraductal Oncocytic Papillary Neoplasm to the Ovaries [PDF]

Case Reports in Gastrointestinal Medicine
Objectives Intraductal oncocytic papillary neoplasm (IOPN) is a digestive system tumor typically found in the head of the pancreas. Most often, they remain confined to the pancreas; it is rare that they develop into an invasive carcinoma or metastasize.

Intraductal oncocytic papillary neoplasm of the liver: Case and review of a rare variant

Annals of Hepatology, 2008
Intrahepatic cholangiocarcinoma (ICCA) comprises 10% of all cholangiocarcinoma (CCA). It can be divided into three macroscopic subtypes, the least common of which is characterized by intraductal growth and believed to be more amenable to good outcomes ...

Intraductal oncocytic papillary neoplasm: a benign hepatic cystic neoplasm. [PDF]

BMJ Case Rep, 2017
A 61-year-old Asian man presented with severe right upper quadrant pain which had been worsening for several months. Laboratory results indicated elevated aspartate aminotransferase and alanine aminotransferase. The subsequent ultrasound, CT and MRI showed a large cystic mass with solid components and severe intrahepatic and extrahepatic biliary ductal

Intraductal oncocytic papillary neoplasm (IOPN): two case reports and review of the literature. [PDF]

Transl Cancer Res, 2023
Intraductal oncocytic papillary neoplasms (IOPNs) place at the oncocytic extreme of the intraductal pancreatic neoplasm spectrum and display typical morphological features. Their identification in 1996 by Adsay et al. has been followed by a growing number of cases, paving the way for a deeper understanding of this underestimated entity.

Eosinophilic Biliary Cystic Neoplasm of the Liver: A Case Report of an Unrecognized Subtype of Intrahepatic Biliary Neoplasm. [PDF]

Pathol Int
A distinct multicystic intrahepatic neoplasm composed of low‐grade tumor cells with brush border‐like microvilli and abundant granular eosinophilic cytoplasm is described, for which we propose the term “eosinophilic biliary cystic neoplasm of the liver.” The tumor harbors KRAS p.G12V driver mutation.

Intraductal Oncocytic Papillary Neoplasms of the Pancreas [PDF]

Archives of Pathology & Laboratory Medicine, 2016
Intraductal oncocytic papillary neoplasms (IOPNs) are cystic neoplasms with intraductal growth and complex papillae composed of oncocytic cells. IOPNs have been reported both in the pancreas and biliary tree, and are most likely closely related in these 2 locations. In the pancreas, these rare tumors are now considered 1 of the 4 histologic subtypes of
