A Pathological Assessment of the Microvasculature of Biliary Tract Neoplasms Referring to Pre-Existing Blood Vessels and Vessel Co-Option [PDF]

Cancers
There are several types of microvasculature supplying neoplasms: “newly formed blood vessels” (neoangiogenesis), which are a component of the tumor microenvironment (TME) of invasive carcinoma with wound healing-like reaction; and “pre ...

Biliary tract neoplasms: diagnosis and staging [PDF]

Cancer Imaging, 2007
Most biliary tract neoplasms are malignant and have been traditionally divided into cancers of the gallbladder, the extrahepatic bile ducts, and ampulla of Vater. Although infrequent, bile duct carcinomas and cancer of the gallbladder are not rare. In the United States, an estimated 6000-7000 new cases of carcinoma of the gallbladder and 3000-4000 new ...

Microsatellite Instability in Intraductal Papillary Neoplasms of the Biliary Tract [PDF]

Modern Pathology, 2002
Intraductal papillary neoplasms of the biliary tree are unusual lesions characterized by solitary or diffuse growth along the intra- and/or extrahepatic biliary tract. Biliary papillary neoplasms bear some clinicopathologic similarity to intraductal papillary mucinous neoplasms of the pancreas.
