Figure 5. Histopathological features of the described tumor. The histological diagnosis was NST invasive breast cancer with a cystic wall, poorly-differentiated, of grade 3 (G3), as observed by hematoxylin and eosin staining at magnification ×1 (A) and ×20 (B). Immunohistochemical features of ER (C), PR (D), and HER2 (E) at magnification ×20. ER, PR, and HER2 staining results were all negative. The Ki-67 labeling index was 80% (F) at magnification ×20. The result of staining with basal cytokeratins, CK 5/6 (G), and CK14 (H) was focally positive at magnification ×20.
