A case of endometrioid carcinoma of prostate

Park, Kwan Hyeun; Lee, Sang Eun

Abstract

In the rare group of atypical adenocarcinomas of the prostate, endometrioid carcinoma is thought to be in unique but controversial position among them. In 1967, Melicow and pachter first reported a prostatic malienancy whose pattern was similar to endometrial adenocarcinoma of the female uterus. Because of the distinctive morphologic appearance and location near the prostatic verumontanum, it was suggested that it might originate from the mtllerian (female) remnant, the prostatic utricle, and consequently display estrogen dependence. But recent immunohistochemical and ultrastructural studies suggests that endometriold carcinoma of prostate is a unusual histologic variant of prostatic duct adenocarcinoma. We experienced a case of endometriold carcinoma of prostate, who was treated by radital surgery and pelvic lymph node dissection with radiation. And this may be the first reported case of its kind in Korea. Till now he is under the follow up for 2 years and 2 months after surgery with no evidence of disease.
