title: Transition zone carcinoma of the prostate.
abstract: Transition zone carinoma of the prostate can present a difficult diagnostic challenge. This entity should be considered in patients who have high prostate specific antigens (PSA) in relation to prostate volume and negative transrectal ultrasounds and ultrasound-guided biopsies. A transurethral biopsy of the prostate may be necessary to obtain the diagnosis.
