Unilateral primary ovarian leiomyoma in adolescent: a case report

Background Primary ovarian leiomyoma is a rare, usually small and incidentally detected neoplasm, clinically indistinguishable from subserous leiomyomas and ovarian fibromas, until histopathological confirmation. Case report We report a rare case of unilateral, ovarian leiomyoma that was not associated with uterine tumor in a 17-year-old woman. Trans abdominal ultrasonography and magnetic resonance imaging (MRI) revealed a pelvic mass (15 cm × 12 cm). Conclusion At laparotomy, unilateral salpingo-oophorectomy was performed and histologic examination revealed a leiomyoma arising primarily in the ovary.
