Figure 2: Case 2 (a) Intact urothelial lining epithelium with a spindle cell tumor stretching the overlying epithelium (H and E stain x40). (b) The tumor cells are oval-to-spindle shaped with blunt ended nuclei (H and E stain ×400); inset shows negativity for Pancytokeratin, whereas the urothelial lining is positive (IHC : AE1/AE3 x40). (c) Urine cytology shows discreet population of spindle cells (Pap stain ×100). (d) Individual tumor cells show moderate pleomorphism and blunt nuclear ends (Pap stain ×400)
