Severe hepatitis during ketoconazole therapy.

Ketoconazole is an imidazole derivative recently developed as an antifungal agent. There have been only a few established cases of hepatotoxicity in the literature. This report describes a case of presumed ketoconazole hepatotoxicity characterized by the development of severe hepatitis with marked centrilobular necrosis. The lack of hypersensitivity reactions in clinical findings and centrilobular location of necrosis suggested a host idiosyncrasy with metabolic abnormality as the effect of ketoconazole in the present case.
