title: [A case of endometrioid carcinoma of the prostate].
abstract: A case of endometrioid carcinoma of the prostate is reported. A 64-year-old man was admitted to our department with initial macrohematuria and dysuria. The transrectal ultrasonogram showed remarkable prostatic hypertrophy and the serum level of both prostatic specific antigen (PSA) and prostatic acid phosphatase (PAP) ranged within normal limits. Urethrocystographical and cystoscopical findings indicated prostatic hypertrophy with elongation of prostatic urethra and mild trabeculation of bladder wall. During transurethral resection of the prostate, papillary tumor was accidentally found in the left lobe near the vermontanum. Histopathological examination revealed adenocarcinoma of the prostatic urethra and the tumor displayed no immunoreactivity for PSA or PAP. Under diagnosis of prostatic urethral cancer total cystoprostatectomy and urethrectomy were performed and ileal conduit was constructed for urinary diversion. As intraductal papillae and complex ramifying glands were histopathologically confirmed in the specimen and the immunohistochemical staining showed positivity of PSA and PAP, the tumor was diagnosed as endometrioid carcinoma of the prostate.
