[Papillary adenocarcinoma of the prostate: report of 3 cases].
We report here 3 cases of papillary adenocarcinoma of the prostate. In all 3 cases, the tumors were discernible on cystourethroscopy and transurethral biopsy established the diagnosis, whereas no significant finding was found on digital rectal examination. Although androgen deprivation therapy was administered in all cases, different surgical procedures were employed according to the stage in each case. In case 1, since the papillary tumor was confined within the prostatic urethra, complete resection was accomplished by transurethral resection (TUR). In case 2, since pelvic lymph nodes metastases were found, local radiation therapy was added. In case 3, since the patient had vesical invasion of tumor total cysto-prostatectomy was performed. Papillary adenocarcinoma of the prostate originates from the prostatic duct, resulting in existence at the "central portion" of the prostate gland. Cystourethroscopy and transurethral biopsy is helpful for diagnosis of this disease, whereas rectal digital examination is useless. As a surgical procedure for the primary site, TUR may be efficient for tumors confined within the prostatic urethra, although more extensive surgery may be necessary for those with a more invasive profile.
