A left borderline serous ovarian tumor stage I (FIGO) was discovered and treated in a 26-year-old black nulliparous woman, by conservative approach (laparotomy, salpingo- oophorectomy). In a six months interval she had a 7.5 x 7.1 x 5.7cm multilocular contralateral tumor with septa and vegetative areas and in a year interval a CT showed a 8.4 x 7.4 x 7.0 lesion that precluded a follicular aspiration. The authors discuss the multidisciplinary strategy and the approach with the couple: the best option considered would be the resection of the tumor remaining attached to a new study pelvic. If possible uterine conservation should be held for further procedure of oocyte donation. Two years from the first surgery she had the second laparotomy and six months later she had an ICSI with oocyte donation. She became pregnant and delivered two 34 week-pregnancy boys through C-section due to hypertension plus preeclampsia. There happened a post- operative intestinal obstruction that required a new surgical approach to adhesions lysis. There was no report of tumor lesions then. Seven months later, mother and children are doing well. Comments are made about borderline ovarian tumors and fertility-sparing approaches.
