This is a leiomyosarcoma protruding from myometrium into the endometrial cavity of this uterus that has been opened laterally so that the halves of the cervix appear at right and left. Fallopian tubes and ovaries project from top and bottom. The irregular nature of this mass suggests that is not just an ordinary leiomyoma.
