General description

Anti-hepatocyte specific antigen, also known as anti-Hep-Par1, recognizes both benign and malignant liver-derived tissues including such tumors as hepatoblastoma, hepatocellular carcinoma, and hepatic adenoma. It recognizes both normal adult and fetal liver tissue. The typical pattern is a granular cytoplasmic staining. This antibody is useful in differentiating hepatocellular carcinomas with adenoid features from adenocarcinomas, either primary in the liver or metastatic lesions to the liver.1-3 In labeling hepatoblastoma, it is useful in differentiating this entity from other small round cell tumors.4,5

Hepatocyte paraffin 1 (Hep Par 1) is a monoclonal antibody considered almost specific for normal and neoplastic hepatocytes, that can be used on formalin-fixed paraffin-embedded tissues. Hep Par 1 reactivity has been demonstrated consistently in hepatocellular carcinomas and hepatoblastomas but

The distinction of hepatoblastoma, especially the embryonal type, from other small, round-cell tumors of childhood can sometimes be difficult. Polyclonal anticarcinoembryonic antigen (pCEA) and Hepatocyte Paraffin 1 (Hep Par 1) are immunohistochemical markers that are useful in the diagnosis of
