case_images: Histologic features of the tumor: (a) HE Staining x 40: modular malignant epithelial proliferation overlayed by hyperplastic epidermis with paget's lesion. (b): HE Staining x 40: trabecular proliferation centrated by necrotic areas. (c): HE Staining x 400: Cuboid epithelial cells with indistinct borders amphophilic cytoplasm and hyperchromatic nuclei. Figures of mitoses are frequent. (d): positive immunostain of this tumor cells by the anti cytokeratine 7. (e): Diffuse and intensive immunostain of the tumor cells by the anti Her-2/neu
