title: Brenner tumor and mucinous cystadenoma of borderline malignancy in a patient with Turner's syndrome.
abstract: A 64-year-old woman with a 45,X karyotype and Turner's syndrome and recent onset of right lower quadrant pain was found to have a mucinous cystadenoma with focal areas of borderline malignancy and a typical Brenner tumor in the right adnexa. Ovarian tumors in patients with a 45,X karyotype and Turner's syndrome are extremely rare. The present paper is the first report of concurrence of these 2 tumors in an affected individual. The simultaneous occurrence and intimate admixture of these tumors in a patient believed to be devoid of germ cells would seem to favor a common histogenesis from the germinal epithelium.
