HBV cirrosis: The surface antigen can be detected by biopsy, orcein tinctions (emery hepatocytes), and immunohistochemistry (surface antigen and anticore). Evolution Stages: a) Early or incipient (non-defined nodes, a lot of fibrosis and architectural alteration); b) established (nods completely surrounded by fibrotic bands). Histological Stages: a) active (main necrosis and inflammation; and cholestasis); b) inactive (little necrosisor inflammation). Types of Hepatocarcinomas: trabecular-clear cells- adenoid-solid-scirrhous. The immunohistochemistry helps to define the type using the hepatocellular antigens, carcinoembryonic antigen, cytokeratin, chromogranins and synapto-physins.

Palabras clave : hepatocellular carcinoma; cirrhosis; hepatocellular dysplasia; hepatocarcinogenesis by hepatitis B virus; emery hepatocytes; immunohistochemistry.
