Molecular and immunohistochemical analysis of intraductal papillary neoplasms of the biliary tract

Human Pathology, 2003
Intraductal papillary neoplasms (IPNs) of the biliary tract are uncommon lesions that may be solitary or may spread extensively along the biliary tree. Some biliary IPNs are histologically and radiologically similar to intraductal papillary mucinous tumors (IPMNs) of the pancreas and present a risk for progression to invasive cholangiocarcinoma. Unlike

Oncocytic papillary neoplasms of the biliary tract: a clinicopathological, mucin core and Wnt pathway protein analysis of four cases

Pathology, 2007
AIMS: Oncocytic change in papillary neoplasms of the biliary tract is a very uncommon finding with little known about pathogenesis, immunophenotype and prognosis, especially in comparison to similar lesions in the pancreatic ductal system. We report four

Biliary tract neoplasms: update 2003

Current Opinion in Oncology, 2004
Biliary tract neoplasm is one of the most aggressive malignancies, with a very poor prognosis. Most cancers of the biliary tract will have grown beyond the limits of curative resection by the time they become clinically evident. This reality has fostered therapeutic nihilism, and most physicians and surgeons, in their pessimism, have to run ambitious ...

Cytomorphology of intraductal papillary neoplasm of the biliary tract

Diagnostic Cytopathology, 2019
AbstractIntraductal papillary neoplasms of the bile duct (IPNBs) are papillary epithelial proliferations with delicate fibrovascular cores within dilated bile ducts. They are thought to be premalignant lesions with potential to progress invasive tumors. To our knowledge, there are no prior descriptions of IPNB cytomorphology.

Biliary Tract Neoplasms: A Simple Management Technique

Southern Medical Journal, 1984
This paper presents a simple, fast, and accurate afterloading method of delivering high radiation dose to tumors of the biliary tract, using radioactive iridium through a biliary drainage catheter. A Tuohy Borst sidearm adaptor permits concurrent drainage.

Operative endoscopy in the management of biliary tract neoplasms

The American Journal of Surgery, 1976
Operative endoscopy of the biliary system has been employed with ever increasing frequency at the UCLA Hospital during the last three years. In addition to its established value with respect to disclosing unsuspected stones in the bile ducts, choledochoscopy has been of great value in terms of more accurate diagnosis and staging of periampullary and ...

Early neoplasms of the ampulla and intrapancreatic biliary tract

Diagnostic Histopathology, 2015
Abstract The classification of precursor lesions arising in the ampullary region and in the intrapancreatic biliary tract has recently evolved. It largely includes adenomas, papillary-tubular neoplasms of the ampulla and intrapancreatic bile duct, and flat dysplasia/biliary intraepithelial neoplasia (BiIIN).

The case for parallel classification of biliary tract and pancreatic neoplasms.

Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc, 1996
Most primary epithelial neoplasms found in the intrahepatic and extrahepatic biliary tracts and the pancreas have similar histologic appearances. The degree of similarity of tumor types is greater than is commonly appreciated and extends to rare neoplasms.

Biliary tract neoplasms from common to rare: diagnosis, assessment, and management

Abdominal Radiology
Biliary tract neoplasms include a diverse set of benign and malignant entities that share both clinical presentations and imaging features. Radiologists need to understand the diagnostic features of these neoplasms to recognize them at initial diagnosis, and we must also provide key information to our surgical and oncology colleagues to facilitate ...
