Abstract
Mucinous adenocarcinoma of the prostate is rare and its biological behavior is not well known. We report a case of mucinous adenocarcinoma of the prostate, which was treated successfully with castration. Positivity for prostatic specific antigen by immunohistochemistry confirmed the prostatic origin of this tumor. A review of the literature revealed 30 authentic cases. Prostatic mucinous adenocarcinoma has been said to be different clinically from ordinary prostatic adenocarcinoma. It is insensitive to hormonal therapy, rarely produces acid phosphatase and rarely metastasizes to the bone. However, our case, together with the frequent presence of coexisting acinar elements in mucinous adenocarcinoma, indicates no significant difference in the clinical behavior between mucinous and ordinary acinar carcinomas.
