The case of a 39-year-old female with mild renal failure and asymptomatic hyperuricemia who developed generalized exanthema, fever and eosinophilia followed by progressive jaundice and worsening of renal function 19 days after the initiation of treatment with alopurinol (300 mg/day) is reported. Liver biopsy showed a combination of mixed inflammatory infiltrate with abundant eosinophils and periportal necrosis and bridging, together with cholestasis and moderate steatosis. A review of the literature is made providing detailed analysis of other cases with preexisting renal failure and the role of renal dysfunction as a risk factor is discussed.
