Cotyledonoid dissecting leiomyoma of the uterus: a case report and review of the literature
Abstract
Background
Cotyledonoid dissecting leiomyoma, also named Sternberg tumor, is a rare variant of uterine leiomyoma. The tumor is benign, but the appearance and growth pattern are unusual and alarming. In this article, we report a case of cotyledonoid dissecting leiomyoma in a 55-year-old woman as well as review relevant literature.
Case presentation
We report a case of cotyledonoid dissecting leiomyoma in a 55-year-old Iranian woman who presented with vaginal bleeding 4 months after menopause. Ultrasound showed two heterogeneous hypoechoic masses on the uterine fundus. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed for the patient. Macroscopically, a large heterogeneous intramural mass (140 mm × 120 mm × 120 mm) with a grape-like exophytic mass on the fundus was observed. Her health status was good after surgery, and the patient was discharged from the hospital after 2 days. In a 1-year follow-up period, no recurrence or any other related complications were found.
Conclusion
It is important to recognize this rare variant of leiomyoma to prevent aggressive and inappropriate overdiagnosis and overtreatment. It is suggested to try to use frozen sections for better diagnosis and to preserve fertility in young women suffering from this lesion.
