Sclerosing stromal tumor of the ovary.

Sclerosing stromal tumors are benign ovarian neoplasms of the sex cord stromal category which occur predominantly in the second and third decades of life. Herein, we report a 26-year-old woman who developed a sclerosing stromal tumor of the ovary with irregular menses but normal hormonal status. She was suspected to have a malignant tumor and underwent bilateral oophorectomy.
