Leiomyomas in uterine remnants associated with vaginal agenesis.

A premenopausal woman with vaginal agenesis underwent surgery for leiomyomas in rudimentary uterine horns. Immunohistochemical study of surgical specimens revealed that progesterone receptors are distributed in the nuclei of a majority of the leiomyoma cells and in the nuclei of a minority of the myometrial cells. Estrogen receptors are not detected in the surgical specimens.
