ENDOMETRIOID ADENOCARCINOMA OF PROSTATIC URETHRA PRESENTING WITH ANTERIOR URETHRAL IMPLANTATION

Endometrioid adenocarcinoma of the prostatic urethra is presented in an eighty-four-year-old white man who had been treated for transitional cell carcinoma of bladder and microacinar adenocarcinoma of prostate prior to presenting with an implanted anterior urethral mass. The differential diagnosis of the papillary lesions encountered in the prostatic and penile urethra is reviewed. Based on the literature, a comparative study between both pure and mixed endometrioid carcinoma and microacinar prostatic carcinoma was done. The study aimed to elicit more data about the clinical features of endometrioid carcinoma and included several clinical parameters (age, presenting symptoms, rectal examination findings, serum acid phosphatase level, and metastasis at presentation). The general impresson gained from this study is that no significant clinical difference exists between these two histologic variants of prostatic carcinoma.
