52.Viral hepatitis C, liver, low power microscopic
This is a case of viral hepatitis C which is at a high stage with extensive fibrosis and progression to macronodular cirrhosis, as evidenced by the large regenerative nodule at the center right. At present, the sole laboratory test for identification of this form of viral hepatitis is the hepatitis C antibody test. Hepatitis C accounts for most (but not all) cases formerly called "non-A, non-B hepatitis".
