To evaluate uncommon types of borderline ovarian tumors and define the clinical, surgical and pathological features.

Material and Methods:

Seventeen patients who were treated in our hospital between 1990 and 2017 were identified. Patients’ data collected from gynecological oncology clinic electronic database, patients’ file and pathology report. Conservative surgery was defined as preservation of uterus and at least one part of one ovary.


The mean age was 47 years (range; 22-70). Based on histopathological tumor type, there were mixed tumor in five (29.4%) patients, endometrioid type in nine (52.9%), seromusinous type in two (11.8%) and Brenner type in one (5.9%). Conservative surgery was performed in 4 patients. Two patients endometrioid BOT had synchronous endometrial pathology, including one (11%) patient with endometrial cancer, one (11%) with endometrial hyperplasia without atypia and 3 (33%) patients had endometriosis. The median follow-up was 19 months (range, 1-137). No recurrence was observed during the follow-up period.


In that small volume case series, it could be said that non-serous / non-mucinous BOT has excellent prognosis. However endometrial pathology should be checked in endometrioid type.
