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