Figure 6. IHC staining of ICC. IHC results of the breast carcinoma reveal a luminal phenotype (all, 10× objective). (A) The carcinoma had diffusely strong ER positivity with (B) nearly negative PR positivity (<1 weakly PR+ cell/100 cells). (C) More than 10% of tumor cells showed moderately staining membranous c-erbB2 positivity (c-erbB2+ equivocal), and (D) a Ki-67 labeling index of about 30%. IHC – immunohistochemistry; ICC – invasive cribriform carcinoma; ER – estrogen receptor; PR – progesterone receptor.
