Hepatocyte Specific Antigen, also known as Hepatocyte Paraffin 1 (Hep Par 1), is expressed in normal and neoplastic hepatocytes. Hep Par 1 is a highly specific marker for HCC, although several non-hepatic tumors occasionally can show some Hep Par 1 positivity.
A diffuse strong granular cytoplasmic pattern is seen with Hep Par 1 staining in this HCC.
This example of HCC shows a more variable staining reaction with Hep Par 1.
Normal pancreatic tissues show a negative staining reaction with Hep Par 1.
