Ciprofloxacin is a fluorinated quinolone antibiotic with relatively low occurrence of adverse side effects. However, increasing evidence suggests that ciprofloxacin may cause severe liver damage. Until now, 14 cases of ciprofloxacin-associated liver injuries have been reported. We describe a case of a 22-year-old male who developed hepatic failure after intake of ciprofloxacin. The patient had been treated with 2 x 250 mg ciprofloxacin per day. He presented with symptoms of acute liver failure 14 days later. Liver biopsy revealed extensive hepatocellular necrosis involving zones 3 and 2 of hepatic acini and a mixed inflammatory infiltration containing abundant eosinophils. Symptoms resolved after corticoidsteroid therapy. In the present paper, we report the clinico-pathological characteristics of a case of ciprofloxacin-associated acute hepatic failure and discuss the current literature.
