title: Laparoscopic repair of a post-myomectomy spontaneous uterine perforation accompanied by a bizarre tumor resembling polypoid endometriosis.
abstract: Among various long-term complications after previous myomectomy, increasing risk of uterine rupture or dehiscence during pregnancy, and in particular during labor, has been widely recognized. In contrast, the world literature includes no case report of spontaneous uterine perforation or rupture after myomectomy in a nonpregnant woman, and only 1 case of iatrogenic uterine perforation after uterine artery embolization has been reported. Recently, we encountered an extremely rare case of spontaneous uterine perforation after previous myomectomy accompanied by a bizarre tumor resembling polypoid endometriosis, which was successfully treated via laparoscopic surgery. The patient reported genital bleeding and lower abdominal pain. Preoperative magnetic resonance imaging and intraoperative findings clearly demonstrated the presence of a uterine wall defect and a multicystic tumor that had developed from the perforated portion of the uterus. The patient underwent successful laparoscopic surgery for repair of the perforated uterus and resection of the tumor. The clinicopathologic diagnosis of the tumor was tentatively confirmed as an endometriosis-like lesion resembling polypoid endometriosis. We speculate that the cause of the tumor was retrograde menstruation, as in the pathogenesis of endometriosis.
