The aim of this study was to report results of a multicentric Tunisian study concerning the clinical practice and the management of pediatric ovarian masses and to identify the factors that are associated with ovarian preservation.</p> <p><strong>Materials and Methods: </strong>Between January 2000 and December 2015, 98 pediatric patients (<14 years) were surgically treated for ovarian masses at the five pediatric surgery departments in Tunisia.</p> <p><strong>Results: </strong>Ninety-eight patients were included in this study. The mean age of the patients at time of surgery was 8.46&plusmn;4.87 years. Sixty-three ovarian masses (64.3%) were non- neoplastic lesions, 24 (24.5%) were benign tumors, and 11 (11.2%) were malignant neoplasms. Conservative surgery (ovarian preserving surgery) was successfully performed in 72.4% of the benign lesions whereas only three patients (27.3%) with malignant tumors underwent ovary-sparing tumor resection (p<0.001). The mean diameter of the tumors in the patients who underwent oophorectomy was significantly larger than that in the patients who underwent conservative surgery (7.8 &plusmn; 3.9 cm vs. 5.7 &plusmn; 2.9 cm, respectively, p=0.001).</p> <p><strong>Conclusion: </strong>In the present study, the risk factors for oophorectomy were a malignant pathology and large tumor size. In accordance with the Gynecologic Cancer Intergroup consensus, it is recommended that surgical management of ovarian masses in children should be based on ovarian preserving surgery.</p> <p></p> Children, Oophorectomy, Ovarian Mass, Ovarian Preservation 133 139 http://ijpho.ssu.ac.ir/browse.php?a_code=A-10-70-125&slc_lang=en&sid=1 Imen Abid No Mohamed Zouari Yes Mohamed Jallouli No Sondes Sahli No Aicha Bouden No Rabiaa Ben Abdallah No Fatma Trabelsi No Asma Jabloun No Awatef Charieg No Chaima Mrad No Mariam Marzouki No Sana Mosbahi No Aziza Ezzi No Roumayla Mootamri No Mourad Hamzaoui No Nejib Kaabar No Said Jlidi No Abdellatif Nouri No Riadh Mhiri No
