Malignant intraductal oncocytic papillary neoplasm of the common bile duct.
Recently, several cases of intraductal oncocytic papillary neoplasm (IOPN) of the liver and hepatic bile ducts have been reported. The author herein reports the first case of IOPN of the common bile duct (CBD). A 78-year-old man was admitted to our hospital because of jaundice. Imaging modalities including US, CT, MRI revealed an intraductal tumor of the middle CBD and biliary dilation distal t...
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 کاملGallbladder papillary neoplasms share pathological features with intraductal papillary neoplasm of the bile duct
Intraductal papillary neoplasm of the bile duct (IPNB) has been widely recognized. However, the knowledge of intracystic papillary neoplasm of the gallbladder (IPNG) including papillary adenoma and adenocarcinoma is not well defined. In this study, we compared the clinicopathological and immunohistochemical features between 32 IPNG cases and 32 IPNB cases. IPNG-1 (low-high grade dysplasia) exhi...
متن کاملClinicopathological characterization of so-called "cholangiocarcinoma with intraductal papillary growth" with respect to "intraductal papillary neoplasm of bile duct (IPNB)".
Cholangiocarcinoma (CC) of the biliary tract occasionally presents a predominant intraductal papillary growth in the bile ducts, called as biliary tract carcinoma (BTC) of papillary growth (PG) and intrahepatic CC (ICC) of intraductal growth (IG) type. Recently, intraductal papillary neoplasm of bile duct (IPNB) has been proposed as a pre-invasive biliary neoplasm. This study was performed to c...
متن کاملAn Intraductal Papillary Neoplasm of the Bile Duct at the Duodenal Papilla
In recent years, the disease concept of intraductal papillary neoplasm of the bile duct (IPNB) has been attracting attention as a biliary lesion that is morphologically similar to intraductal papillary mucinous neoplasm (IPMN), which is considered to be a counterpart of IPMN. However, there are few reports on IPNB, and a consensus regarding the features of this disease is thus lacking. We exper...
