| We report here on three cases of prostatic transitional cell carcinoma (TCC), two confirmed by
transrectal ultrasonography (TRUS)-guided core biopsy and one by transurethral resection of the
prostate. TCC was found in the right distal ureter in one case, in the urinary bladder in another, and
was confined within the prostate in the third. On gray-scale ultrasonography (GSUS), two cases
showed focal, low echoic lesions in the outer gland, and differentiation between the inner and outer
glands was difficult. The third case showed no definite focal prostatic lesion. On color Doppler
ultrasonography (CDUS), two cases showed diffusely increased blood flow in the entire prostate,
and the third showed focally increased blood flow in the inner gland. The serum prostatic specific
antigen (PSA) levels were normal in all three patients. The GSUS and CDUS findings of TCC involving
the prostate were similar to those of prostatic cancer. In the case of normal serum PSA
levels, the presence of focal, low echoic lesions and increased blood flow of the prostate in those
patients with previous or current TCC in the bladder or upper urinary tract may be the distinguishing
manifestations of TCC involving the prostate. |
