Image Description
This image shows intraductal urothelial carcinoma within prostatic ducts in a patient with a high-grade bladder tumor. These patient usually have carcinoma-in-situ of the prostatic urethra and the tumor appears to spread first into more centrally located prostatic ducts. Highly pleomorphic tumor cells have insinuated themselves between the basement membrane and the ductal epithelium which appears lifted off from its place.
