We describe a case of mucinous adenocarcinoma which originated from the prostatic urethra, extended to right ischiorectal fossa and the seminal vesicles, and metastasized to bone. This case was identical to adenocarcinoma arising from the urinary bladder and differed from mucinous adenocarcinoma of the prostate. This tumor was negative immunohistochemically for prostate-specific antigen and prostate-specific acid phosphatase and positive for carcinoembryo -nic antigen. In terms of therapy, the distinction between mucinous adenocarcinoma of urinary bladder-type arising from the prostatic urethra and mucinous adenocarcinoma of the prostate is significant.
