肝外胆道闭锁:肝硬化福尔马林固定呈暗绿色


肝外胆道闭锁为肝脏或胆总管的狭窄与炎症,这是一例死于肝外胆道闭锁的3个月婴儿。该病导致显著的胆汁淤积和肝内胆管增生、纤维化、肝硬化。肝脏如岩石般坚硬。福尔马林作用于发生显著胆汁淤积的肝脏中的胆色素,将胆红素转化为胆绿素而呈暗绿色。
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.
