This 3 month old child died with extrahepatic biliary atresia, a disease in which there is inflammation with stricture of hepatic or common bile ducts. This leads to marked cholestasis with intrahepatic bile duct proliferation, fibrosis, and cirrhosis. This liver was rock hard. The dark green color comes from formalin acting on bile pigments in the liver from marked cholestasis, turning bilrubin to biliverdin.
