Hep Par 1 produced distinctive granular staining of all benign hepatocytes and stained 30 HCCs in a heterogeneous manner, irrespective of the degree of differentiation. While labelling all cases of combined HCC-CC, the antibody also stained the mucus-secreting cells of four cases of pure CC. Anti-CK19 produced distinctive staining of bile ducts and CC but also decorated four HCCs and 10 metastatic tumours. Factor XIIIa was not found in normal, reactive or neoplastic hepatocytes. CK20 was found in some cases of HCC and CC and in all cases of metastatic carcinomas from the colon.〈section xml:id="abs1-3"〉〈title type="main"〉ConclusionsHep Par 1 was a sensitive marker of hepatocytes but its variable staining in HCC may produce false negative results in small biopsies and it was occasionally found in CC. The highest diagnostic yield was obtained when anti-Hep Par 1, CK19 and CK20 were used in a panel. Factor XIIIa staining has no role in the diagnosis of liver cancers.Type of Medium: Electronic ResourceURL:
