This is an example of adenosquamous carcinoma in a 79 y/o male who had been treated with androgen deprivation therapy and radiation for prostate cancer. He was lost to follow-up and presented nine years later with a large tumor in his bladder causing obstructive symptoms. The recurrent tumor showed a spectrum of findings, including usual acinar type prostatic adenocarcinoma, adenosquamous carcinoma, and squamous cell carcinoma.
