Combined hepatocellular‐cholangiocarcinoma (HCC‐CC), also known as mixed HCC‐CC, is a rare (incidence among primary liver cancer ranges from 1.0% to 4.7%) but an increasingly recognized primary malignant neoplasm in the liver. Cholangiocarcinomas are a diverse group of tumors that are presumed to originate from the biliary tract epithelium either within the liver or the biliary tract. Gallbladder malignant: gallbladder carcinoma carcinoma in situ. Can also be micropapillary, acinar, or cord like The major function of the bile duct is to move a fluid called bile from the liver and gallbladder to the small intestine, where it helps digest the fats in food.
