New Feature for Histopathologic Diagnosis of Early Hepatocellular Carcinoma - Degree of Nuclear Concentration -

In the field of histopathologic diagnosis, differential diagnosis of borderline lesions is a serious problem. Especially, differential diagnosis between early welldifferentiated hepatocellular carcinoma (ewHCC) and noncancer is difficult because the cellular atypism of ewHCC is very low. Nuclear density (number of nuclei per unit area) is one of features effective to diagnose ewHCC.
