Normal pregnancy and delivery following conservative surgery and chemotherapy for ovarian endodermal sinus tumor.

Management of younger patients with early stage ovarian endodermal sinus tumor who desire to have children can be a challenging problem. However, after an adequate and thorough staging procedure for the patient's tumor status, a Stage Iai endodermal sinus tumor may be treated with conservative surgery only, followed by chemotherapy. Successful pregnancy and delivery following unilateral adnexectomy and chemotherapy for ovarian endodermal sinus tumor have been reported only once [J. P. Forney, Obstet. Gynecol. 52, 360 (1977)]; the second reported case is presented here. It should be pointed out that strict follow-up and reliability of the patient are mandatory for such conservative therapy.
