Although liver metastasis is commonly found in cancer patients, fulminant hepatic failure secondary to diffuse cancer infiltration into the liver is rare. Liver metastasis-induced fulminant hepatic failure has been reported in patients with primary cancer of the gastrointestinal tract, breast and uroepithelium, and in patients with melanoma and hematologic malignancy. Small cell lung cancer is so highly invasive that hepatic metastasis is common, but rapid progression to fulminant hepatic failure is extremely rare. We report here on a case of a patient who died because of rapid progression to fulminant hepatic failure as a result of hepatic metastasis of small cell lung carcinoma.
