An example of a case with intratumoral HER2 heterogeneity (case # 20; Table 4) is shown with its hematoxylin and eosin stain counterpart (panel a, 10× objective). The HER2 by IHC shows a strong reaction in the upper and a weak or no reaction in the lower parts of the photomicrograph (panel b, 10× objective). The inset in panel B shows strong cell membrane staining of the HER2 by IHC in the overexpressed part of the tumor (40× objective)
