Comments:
Inverted urothelial papilloma showing classic trabecular growth pattern into the lamina propria. The overlying urothelium has a smooth surface and clear cytoplasm. Interestingly, the basal layer of the overlying urothelium has identical appearance to that of the underlying cords and trabeculae.
