Figure 2 Pathological results of left breast tumor and left axillary lymph node biopsies. A: Hematoxylin and eosin-stained sections revealed that the tumor cells grew in a solid and patchy infiltrating manner (original magnification: 200 ×); B: Hematoxylin and eosin-stained sections revealed that the left axillary lymph node was metastatic carcinoma, which was consistent with the breast source (original magnification: 200 ×); C: C-erBb2 (2+) was uncertain in neoplastic cells by immunohistochemical analysis (original magnification: 200 ×); D and E: Estrogen receptor and progesterone receptor were negative in neoplastic cells by immunohistochemical analysis (original magnification: 200 ×); F: Ki-67 was expressed in the nuclei of approximately 40% of tumor cells (original magnification: 200 ×); G: HER-2 was amplified by fluorescence in situ hybridization (original magnification: 200 ×).
