[Ectopic liver in the gallbladder and cholestasis].

A small ectopic liver on serosa of the gallbladder was demonstrated peroperatively in two patients with extrahepatic cholestasis and considerable distention of the biliary system. The histological architecture of the small liver was similar to that of a normal liver, with a minute bile duct communicating with the lumen of the gallbladder. This explains why the cholestasis provoked identical pathological changes in both liver and the ectopic liver tissue.
