BACKGROUND/AIMS: Surgically resected hepatocellular carcinomas (HCC) in patients with non-alcoholic steatohepatitis (NASH) have rarely been described and the clinicopathological characteristics of HCC and non-cancerous liver tissue are still obscure. METHODOLOGY: From 1997 to 2004, 242 patients with HCC underwent hepatic resection at the Hiroshima Red Cross Hospital and Atomic Bomb Survivors' Hospital. Among this group, the diagnosis of NASH was made in 3 patients. RESULTS: All 3 patients with HCC had cirrhosis. The tumor cells contained Mallory bodies and fat. The non-cancerous areas showed nodular regeneration with fatty changes, ballooning degeneration, and mild inflammatory infiltrates, as well as perivenular and perisinusoidal fibrosis. CONCLUSIONS: Patients with NASH and cirrhosis may progress to HCC, and careful follow-up based on tumor markers and imaging modalities, is essential to detect resectable HCC in patients with NASH and cirrhosis.
