Woodchuck Hepatitis Virus Infection
초록
Grossly, the liver exhibits marked cirrhotic changes characteristics of the pre-transformation phase of WHV. Microscopically, focal hepatocyte necrosis and inflammatory cells were observed in midzonal and periportal areas. Bridging portal fibrosis produced pseudolobulation due to entrapment of hyperplastic hepatocytes. Biliary hyperplasia, ductal cell proliferation, and increased amounts of fibrous connective tissue expanded portal areas and extended into periportal areas. Myofibroblasts stained positive for -SMA were detected in proliferating fibrotic tissue and sinusoids.
