Glandular mammary adenocarcinoma, immunohistochemistry for alpha smooth muscle actin: myofibroblasts located in the stroma of the neoplasm show strong cytoplasmic labeling for alpha smooth muscle actin. A mammary tubule adjacent o the tumor has been invaded by neoplastic cells. This mammary tubule contains two residual myoepithelial cells (arrowheads) which label strongly for alpha smooth muscle actin. Neoplastic cells are not labeled. |
