title: Mixed ovarian tumor composed of Brenner and thyroid elements.
abstract: An exceedingly rare ovarian neoplasm composed of mixed thyroid and Brenner tumor is reported. Review of the literature yielded only one well-documented case previously described. Although the possibility of a "collision" of two different tumors cannot be completely discarded, a possibility of an endodermal teratoma (thyroid-urothelium) is also proposed.
