Abstract

Sclerosing stromal tumor (SST) is a rare benign ovarian neoplasm of stromal origin. This disease most frequently occurs in young women under 30 years old.

15-year-old girl presented with a right ovarian complex cystic mass on abdominal ultrasonography. The CA-125 value was increased mildly. Other tumor markers were normal. Pelvic magnetic resonance imaging showed a large right ovary including heterogenic area, thick septa and contrast-enhanced cystic area. Intraoperatively, a hard, lobular, whitish-yellow fibrotic ovarian tumor including cystic area was identified. Oophorectomy was performed. Histologically, SST was reported.

It must be remembered that when a white-yellow and hard ovarian tissue is identified intraoperativel, the rare SST of the ovary maybe present.
