The histopathology analysis (Figure 3) of the resected tumor showed a biphasic tumor with small luminal ducts surrounded by myoepithelial abluminal cells (Figure 3A: hematoxylin-eosin-saffron, x20). The ki-67 immunohistochemistry proliferative index was about 50% (Figure 3B: MIB1, x20). The immunohistochemistry analysis showed the epithelial phenotype of luminal cells (Figure 3C: pan-keratin AE1/AE3, Figure 3D: epithelial membrane antigen-EMA, x20) and the myoepithelial phenotype of abluminal cells (Figure 3E: smooth muscle actin, Figure 3F: vimentin, x20).
