What are rare types of prostate cancer?

Mark Vogel (Board Certified Urologist) gives expert video advice on: What is an 'adenocarcinoma' in prostate cancer?; What is a 'small cell carcinoma' in prostate cancer?; What is a 'squamous cell' in prostate cancer? and more...

Squamous cell, small cell, transitional cell; these would all be cancers that would be very rare in the prostate as a cancer of the prostate organ itself. They may be from adjacent organs or really represent metathesis from a distant organ to the prostate.
