Sclerosing stromal tumor of the ovary is believed to be a rare, benign, sex cord stromal tumor occurring predominantly in younger women in the 2nd and 3rd decades of their life. The prevalent clinical presentations include pelvic or abdominal pain, mass, or menstrual changes. Even though it is occasionally accompanied by hormonal manifestations, virilization as a result of androgen production by the tumor is rare. The present research was conducted to present a rare case of bilateral sclerosing stromal ovarian tumor in a 20-year-old patient with irregular menstruation and pelvic pain. All of the sclerosing stromal tumors were benign and were treated successfully with enucleation or unilateral oophorectomy.
