Abstract
A paraovarian tumor of borderline malignancy is rare, forming 2-3% of paraovarian tumors. We presented a 35-year-old woman with a paraovarian tumor of borderline malignancy. Pelvic ultrasonography and MRI revealed a right-sided, 6-cm cystic adnexal mass. Laparoscopy showed a paraovarian tumor, and laparoscopic cystectomy without rupture was the initial treatment. Pathologic examination revealed borderline malignancy. Thirty-five days after the surgery, right salpingo-oophorectomy, biopsy of the omentum and peritoneum, and peritoneal washing were performed via laparoscopy. All histological and cytological findings were negative. The patient showed no clinical evidence of the disease over 36 months after the first treatment. Diagnosis and operative procedure of this tumor were discussed in this report.
