Figure 1: (a) Gross photograph of micropapillary carcinoma showing diffuse thickness of the urinary bladder. Histology showing predominant micropapillary architecture (b) (H and E, ×100), pseudoglandular or ring pattern (c) (H and E, ×200), focal glandular pattern with goblet cells (d) (H and E, ×200) and extensive deep muscle invasion (e) (H and E, ×40). Immunohistochemistry showing abluminal epithelial membrane antigen positivity (f) (IP, ×200), strong cytoplasmic cytokeratin (CK)7 positivity in tumor cells and adjacent normal urothelium (g) (IP, ×100), strong cytoplasmic CK20 expression in tumor cells (h) (IP, ×200) and complete strong membranous Her 2 positivity (i) (IP, ×200)
