A Comparative and Evaluative Study of Two Cytological Grading Systems in Breast Carcinoma with Histological Grading: An Important Prognostic Factor

Figure 1

Infiltrating ductal carcinoma histological grade I—predominantly tubular differentiation, mild variability in nuclear size and shape, and uniformly dispersed nuclear chromatin. Inset (Robinson’s cytological grade I): loosely cohesive cluster of monomorphic ductal epithelial cells exhibiting mild nucleomegaly (1-2 times the size of erythrocytes), smooth nuclear margins with small nucleoli (H&E, ×100; inset: PAP, ×400).
