Iatrogenic hepatic injury.

Liver injury produced by therapeutic drugs is common, and has been increasing in incidence. Drug induced injury can mimic almost all varieties of liver disease. These conditions include cholestasis, steatosis, granulomas, acute and chronic hepatitis, cirrhosis, vascular disorders, and tumors. When confronted with a patient suffering from liver disease, it is imperative for the physician to obtain an accurate history of drug administration.
