  • Title: Hepatocellular carcinoma in primary biliary cirrhosis: an autopsy study.
    Author: Nakanuma Y, Terada T, Doishita K, Miwa A.
    Journal: Hepatology; 1990 Jun; 11(6):1010-6. PubMed ID: 1694811.
    Abstract:
    A survey of Japanese autopsy cases of primary biliary cirrhosis disclosed that hepatocellular carcinoma is apparently becoming a better recognized complication of the advanced stage of primary biliary cirrhosis. Six autopsy cases (five women and one man) of primary biliary cirrhosis associated with hepatocellular carcinoma were obtained from several Japanese institutions and examined. All cases were in an established cirrhotic stage of primary biliary cirrhosis. Hepatocellular carcinoma was incidentally found at autopsy in four cases and, in these, the carcinomas were small in size and number. The other two cases showed advanced hepatocellular carcinoma and one case showed extrahepatic metastasis. Histologically, all cases showed well-differentiated hepatocellular carcinomas. Fatty changes or bile plugs were frequently seen within the tumors. Mallory body clusters and focal deposition of copper-binding protein were consistently found in cirrhotic liver tissues and also in the carcinoma tissues of almost all cases. The presence of atypical adenomatous hyperplasia in the peripheries of some carcinomas suggested that hepatocellular carcinoma in primary biliary cirrhosis may evolve through multiple steps.
