title: Expression of bile duct-type cytokeratin in hepatocellular carcinoma in patients with hepatitis C virus and prior hepatitis B virus infection.
abstract: The clinicopathologic findings in patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) positive for biliary markers, those related to the hepatic progenitor cells, were investigated. Cytokeratin (CK) 19 was reactive for HCCs only in patients with prior hepatitis B virus (HBV) infection. The proportions of patients with prior HBV infection and poorly differentiated HCC were significantly higher among those with CK 19-positive HCC than among those with CK 19-negative HCC. Some HCCs develop from the hepatic progenitor cells in patients with HCV infection and prior HBV infection, which may affect the clinicopathologic findings of HCV-related HCCs.
