case_images: Microscopic examination showed an extensively invasive, high-grade neoplasm involving the bladder wall (Figures 1A and 1B), invading the full thickness of muscularis propria and perivesical adipose tissue but also the stroma of both prostatic lobes.

case_images: Immunohistochemical stains showed expression of vascular markers CD31, CD34 (Figures 4A and 3B) in the tumor cells, patchy positivity for cytokeratin AE1/AE3 (Figure 4C) and negativity for p63 (Figure 4D).
case_images: Immunohistochemical stains: Diffuse expression of CD31 (A) and CD34 (B) in tumor cells (IHC, anti-CD31 and anti-CD34 Abs, 200X). Weak expression of CK AE1/AE3 (C) and negative p63 (D) in neoplastic cells (IHC, anti-cytokeratin AE1/AE3 and anti-p63 Abs, 100x and 200X, respectively).
