Two cases of hyperthyroidism with hepatic manifestations are reported. In both the clinical picture was misleading. In one case, hyperthyroidism was responsible for liver involvement. Hépatic manifestations of hyperthyroidism are both polymorphic and non-specific. Diagnosis should be considered only after outruling other possibilities. In the other case, cholestatic hepatitis developed independantly from hyperthyroidism. The resulting clinical picture was confusing. All patients should be checked for non-thyrotoxic liver disease which may be of prognostic and therapeutic significance.
