Hepatocellular carcinoma in adenomatous hyperplasia of the liver.

ABSTRACT

A hepatocellular carcinoma (HCC) measuring 0.2 cm in diameter was found in the center of an adenomatous hyperplasia (AH) measuring 1.7 cm in diameter in a cirrhotic liver. The liver cells of the AH showed a marked fatty change and contained many Mallory bodies. The AH and HCC were studied in relation to liver cell dysplasia in 108 surgically resected livers. The AH was mainly associated with fully developed cirrhosis in 5 (71%) of the 7 cases. The liver cell dysplasia, however was accompanied largely by fibrosis and early-stage incomplete septal cirrhosis in 10 (67%) of the 15 cases. As far as the active inflammatory change was concerned, a fairly active inflammation was found in only 3 (20%) of the 15 livers with liver cell dysplasia, but in 4 (57%) of the 7 livers with AH.
