The results of immunohistochemical staining. (a) Both urothelium-like cell nests and ill-defined lobular clusters of spindled epithelial cells are positive for pancytokeratin. (b) The urothelium-like cell nests are positive for CK7, but the spindled epithelial cells are negative. Both urothelium-like cell nests and spindled epithelial cells are also positive in the nuclei for (c) p63 and (d) WT-1. Only the well-defined urothelium-like cell nests are diffuselt weakly positive in the cytoplasm for (e) uroplakin-III and diffusely strongly positive in the nuclei for (f) GATA-3. All epithelial cells and stroma are negative for (g) c-KIT and (h) DOG-1
