[Polycystic liver disease].

Polycystic liver disease (PLD) includes three entities in adults : biliary hamartomas which develop as a result of ductal plate malformation, autosomal dominant polycystic liver disease (ADPLD) and autosomal dominant polycystic kidney disease (ADPKD) which occur in the setting of genetic disorders. Hamartomas are asymptomatic and benign. PLD are marked by a steady growth of cysts over time, clinically silent in the majority of cases.
