Qiao's Pathology: Molecular Subtype of Breast Carcinoma: Basal-like
Microscopic photo showing a high grade invasive breast carcinoma. The tumor cells are negative for ER (estrogen receptor), PR (progesterone receptor), and HER2/neu. However, the squamoid tumor cells are strongly positive for CK 5/6 (cytokeratin 5/6) (see insert). Jian-Hua Qiao, MD, FCAP, Los Angeles, CA, USA.
