68.Transitional cell carcinoma, low power microscopic

A transitional cell carcinoma of the urothelium is shown here at low power to reveal the frond-like papillary projections of the tumor above the surface to the left. It is differentiated enough to resemble urothelium, but is a mass. No invasion to the right is seen at this point.
