Hepatic cirrhosis caused by low-dose oral amiodarone therapy.
A 63-year-old man presented with ascites after therapy with amiodarone, 200 mg orally once per day for 22.5 months. A liver biopsy showed grade 3 chronic hepatitis and micronodular cirrhosis. The presence of striking microvesicular steatosis on light microscopy and lysosomal inclusion bodies on electron microscopy suggested amiodarone hepatotoxicity. This is the first reported case of amiodarone-induced hepatic cirrhosis associated with chronic treatment with 200 mg orally once per day for less than 2 years.
