[Hepatic granulomatosis].

Granulomatous hepatitis is not a uniform disease entity but a generic histopathologic diagnosis. The present review of aetiology and epidemiology of granulomas in the liver, shows that in the past tuberculosis and sarcoidosis were the most frequent but there remained a large percentage of "undiagnosis" cases; at the present drug-induced granulomatous hepatitis are frequently reported and "undiagnosed cases" are rare. Analysis of the hystological features of the most common granulomas is presented.
