Fulminant hepatic failure in nonmetastatic renal cell carcinoma.

Paraneoplastic manifestations including reversible abnormal serum liver biochemistry are known to occur in at least one third of patients with renal cell carcinoma. This hepatic dysfunction has always been regarded as benign in nature and attributed to reactive nonspecific hepatitis. In contrast to this belief, we report here a more devastating course of an asymptomatic patient with nonmetastatic renal cell carcinoma which ranged from mere serum liver biochemistry derangement to a fatal end with fulminant hepatic failure within 10 days. To our knowledge, this is the first report of such a case.
