The incidence and characteristics of hepatic tumors -primitive or secondary- were analyzed in a series of 596 patients with cirrhosis and on whom an autopsy was carried out. A hepatic tumor was discovered in 43.6%: 96.5% with histological findings of malignant disease and only 3.4% with benign disease. The tumors discovered showed the following in order of frequency: hepatocellular carcinoma (90.3%), hepatic metastases (4.2%), cholangiocarcinoma (2.3%), adenoma (1.5%), hemangioma (1.2%) and hamartoma (0.8%). Therefore, 10% of the neoplasms located in the cirrhotic liver were different from the hepatocellular carcinoma. In 2% of the subjects with hepatic tumors, two histologically different lesions were found to co-exist in the liver, and in every case it was found to be a hepatocellular carcinoma related to another tumor, which further complicated the diagnosis. The most frequent type of hepatocellular carcinoma was multinodular, although diffuse tumors most frequently developed metastases. When the hepatocellular carcinoma was uninodular and small, distal spread was exceptional. Metastatic infiltration of the liver by neoplasms of different origin, characteristically infrequent in cirrhosis, was always accompanied by spread to other organs and did not appear as a single nodule in any case. We conclude that the correct diagnosis of tumor-related lesions located, in a cirrhotic liver is occasionally difficult during life, especially when the neoplasms are different from the hepatocellular carcinoma.
