Squamous cell carcinoma of the prostate: report of 2 cases and review of the literature

Abstract

Two cases of squamous cell carcinoma of the prostate are reported and criteria for diagnosis are suggested. Squamous cancer, which accounts for 0.5 to 1% of prostatic malignancies, differs from the common adenocarcinoma of the prostate in certain clinical features. It also appears to have a worse prognosis and to be unresponsive to the usual therapies for prostatic cancer, perhaps because of a different cell of origin.
