BACKGROUND: Acute liver failure is a rare complication of metastatic liver disease with a high mortality. Recognition of malignant infiltration of the liver as the cause of acute liver failure could be a diagnostic challenge. PATIENTS: The medical files of 5 patients with acute liver failure due to metastatic liver disease collected over a 4-year period (1997-2000) in our department were reviewed. RESULTS: No patient had a past history of cancer. The interval from jaundice to encephalopathy ranged from 7 to 12 days (median, 10). Physical examination revealed hepatomegaly and deep jaundice in all patients. AST elevation ranged from 147 to 1870 IU/L (median, 716 IU/L) and ALT elevation from 74 to 556 IU/L (median, 138 IU/L). All patients died within 4-14 days (median, 7) of admission. None had papillary edema or decerebrate posture before death. Four patients had concurrent renal impairment. Liver imaging studies in 2 of the 5 patients were nondiagnostic and the malignant liver infiltration was confirmed postmortem. Liver histology in all cases showed massive tumoral infiltration of the hepatic sinusoids with diffuse replacement of hepatocytes. The primary tumors were colon, gastric, small cell lung, pancreas and cancer of unknown origin. CONCLUSIONS: Malignant infiltration of the liver should be taken into account in the differential diagnosis of rapidly progressive liver failure. Although effective chemotherapy has improved the survival of patients with metastatic liver disease, there has been no change in the course and outcome of acute liver failure due to malignant infiltration of the liver over the last 2 decades. A proper diagnosis by liver biopsy is mandatory to prevent such patients from being considered for liver transplant.
