Three cases of Brenner tumor among Korean women seen at the Department of Obstetrics and Gynecology, Presbyteian Hospital, Taegu, Korea, during the period through January, 1958 to March, 1966, are presented. The age incidence was over 48 years. Two of them were in the postmenopausal age group, being 52 and 67 years of age with a parity of 2 and 6 respectively, and the other, premenopausal being 48years of age with a parity of 6. In one of the cases, postmenopausal intermittent genital bleeding occurred. The tumor involvement was unilateral in all cases. Two of them were foung incidentally and were associated with other conditions such as leiomyoma and carcinoma in situ of cervix. In one case, the tumor occurred with a large mucinous cystadenoma. No speciflc clinical features which would lead to the preoperative diagnosis of Brenner tumor were obtained by reviewing the cases. There was no evidence of any endocrine activity or malignant changes of the tumor in any of the 3 cases. The follow-up study revealed no recurrence for as long as 1 month to 4 years. An attempt at extensive review of the literature on Brenner tumor is made in both clinicopathological and pathogenetic aspects.
