| A rare epithelial carcinoma arising either in the gallbladder itself or from the epithelium lining the extrahepatic biliary tree, cystic duct and/or peribiliary gland. The disease has characteristics of nonspecific symptoms, such as abdominal pain, jaundice and vomiting and sometimes mimicking benign biliary diseases. Chronic biliary epithelial inflammation (for example primary sclerosing cholangitis, cholelithiasis, choledocholithiasis, liver fluke infestation) is a major risk factor. |
