case_images: Sections from polypoidal growth [Figure 1a] seem to be composed of cells arranged in tubules, papillae, and tubulocystic areas and at places trabeculae [Figure 1b]. Many cells showed clear cytoplasm [Figure 1c]. Lining epithelium surrounding the tumor showed urothelial carcinoma in situ [Figure 1d].

case_images: Tumor cells showed immunoreactivity for CEA and CK7 [Figure 2a]. Ki67 labeling index [Figure 2b] and p53 [Figure 2c] immunoreactivity were 90% and 95%, respectively.
