Prochlorperazine-induced chronic cholestasis.

A patient with prochlorperazine-induced cholestasis that persisted for more than 2 years is reported. The timing of the onset of jaundice, the clinical, biochemical and histological findings and the subsequent course of this patient were typical of chlorpromazine-induced chronic cholestasis. Despite subsequent resolution of jaundice, liver biopsy performed 2 years after the onset of clinical disease showed fibrous expansion of the portal tracts with focal porto-portal and centro-portal bridging fibrosis, and paucity of inter-lobular bile ducts, a picture simulating that of primary biliary cirrhosis. Long-term follow-up is required to determine whether this patient will progress to frank cirrhosis.
