A total of 25 patients operated on for the indication of adnexal masses diagnosed as borderline ovarian tumors based on frozen section results were included in our study. Patient age, tumor diameter, tumor markers and surgeries performed were discussed in the light of the literature. Statistical analyses were performed using the SPSS software. The patient mean age was 43.84 +/- 11.34 years. The mass was localized in the right (n=13), left (n=11) or both (n=1) adnexal regions. The mean tumor diameter was 12.9 +/- 5.84 cm. Histopathologic examination established the diagnosis of serous borderline (n=14 patients) and mucinous borderline (n=11) ovarian tumors. Although the results of our study are consistent with current literature data, a greater number of current studies should be performed on borderline ovarian tumors, which are defined as a class of tumors different from epithelial ovarian tumors.eninfo:eu-repo/semantics/openAccessOvarian neoplasms, diagnosisOvarian neoplasms, classificationCystadenocarcinoma, serous, diagnosisCarcinoma, ovarian epithelial, diagnosisArticle58129363136332210.20471/acc.2019.58.01.042-s2.0-85066827634Q3WOS:000470874000004Q4
