[Sarcoidosis and primary biliary cholangitis in a patient with cholestasis].

Primary biliary cholangitis and sarcoidosis are both cholestatic liver diseases. Currently, there are no established specific criteria for distinguishing the diseases from each other; diagnosis is based on the anamnesis, as well as the results of physical, laboratory and instrumental examination. The case report presents a female patient with a rare combination of histologically verified liver sarcoidosis and primary biliary cholangitis. Despite the similar clinical manifestations, the approaches to the treatment of these diseases are completely different, that underlines the importance of the differential diagnosis to exclude combined liver damage.
