Abstract
Benign metastatic leiomyoma is a unique event presenting most commonly in premenopausal women especially those with a previous history of gynecological surgery as management of uterine fibroids. In this case report, we investigate a rare case of benign metastatic leiomyoma in a 54-year-old postmenopausal female presented with a huge pelvic mass that was rapidly growing along with pulmonary nodules. The patient is suspected to have leiomyosarcoma which is eventually confirmed pathologically as benign metastatic leiomyoma. Although rare, describing the challenging diagnostic and management approach of such entity is essential and to consider it one of the differential diagnoses of patients who present with similar history.
