primary ovarian leiomyoma in a premenopausal woman: a case report

Primary ovarian leiomyoma is a rare benign ovarian tumor that occurs in women between the ages of 20 and 65. this tumor is usually diagnosed incidentally through pelvic examination or histopathological study after surgery. a definitive preoperative diagnosis is difficult due to the lack of pathognomonic signs or specific imaging features. therefore, histopathological examination and immunohistochemical analysis are considered necessary. the authors report a case of a 49-year-old woman with ovarian leiomyoma who had a history of heavy vaginal bleeding. she underwent laparotomy with a preoperative diagnosis of uterine fibroids.
