A 72-year-old housewife presented with clinical and laboratory signs of acute cholestatic hepatitis. Symptoms had appeared 6 months after she was started on ticlopidine 250 mg/day. Infectious aetiologies were excluded by serology and there was no history of alcohol abuse or use of other drugs. Clinical findings were confirmed by liver biopsy. The drug was discontinued and symptoms gradually subsided. A second biopsy obtained during this phase documented complete resolution of the hepatic damage. A review of the literature shows that the late onset of hepatic toxicity in this case is unique and this is the first report to include histological documentation during the acute phase and after recovery.
