Abstract

Brenner tumor is a rare neoplasm of the ovary and there is general agreement that he tumor is derived from surface (coelomic) epithelium. We have experienced three cases of Brenner tumor in Pathology department of National Medical Center during 4 years and 6 months from Jan. 1975 to June 1979, which comprised 2.1% of 142 all benign ovarian tumors. The size of tumor was variable from microscopic to 15cm. in maximal diameter. Two of them were bilateral and another one had marked calcification in the stroma. One of the three cases was accompanied by mucinous cystadenoma. None of them showed proliferating or malignant pattern.
