Introduction/Background Borderline ovarien tumors account for 10 to 20% of ovarian epithelial tumors. Histologically, They differ from typical ovarian cancers by cell proliferation, mild nuclear atypia and absence of stromal invasion.

These cancers tend to affect women at a younger age than the typical ovarian cancers, with a survival rate of around 90%.

The most important prognostic factors are staging, peritoneal implants and the existence of tumor remnants. Treatment is surgical and should be conservative in women under 40 who wish to become pregnant.

Methodology Nine cases of borderline ovarien tumors treated in the department of gynecology-obstetrics I at the CHU Hassan II in Fez between june 2021 and june 2023 were analyzed retrospectively.

Results Patient age ranged from 29 to 64 years, with an average of 42. the ovarian mass was unilocular in 2 cases, multilocular in 3 cases and of mixed component in 4 cases. The average size was about 14cm which explains the need for laparotomy in most of our patients. 5 patients had mucinous borderline ovarien tumors, 3 serous an 1 brenner tumors.

Conclusion Borderline ovarien tumors had a good prognosis overall the choice of surgery must take into account the patient’s age and desire for fertility. Complete surgery seems to be the best way to prevent reccurence.

Disclosures The authors declare that they have no conflict of interest.
