摘　　要：BACKGROUND Disseminated peritoneal leiomyomatosis(DPL)with myxoid leiomyosarcoma is a rare variant of leiomysosarcoma,and hematuria as a presenting symptom has never been reported.Through this case report,we emphasize the investigation of the etiology,clinical presentation,diagnosis,treatment,and prognosis of DPL with malignant changes mimicking metastatic urinary tract cancer and to help develop further clinical management.CASE SUMMARY We describe a case of DPL with malignant transformation involving the right ureter after laparoscopic hysterectomy.An exploratory laparotomy was performed and all visible nodules were surgically removed.DPL with focal malignant transformation to myxoid leiomyosarcoma was confirmed based on pathology results.CONCLUSION Professionals who preoperatively diagnose DPL with malignant change to myxoid leiomyosarcoma involving the genitourinary tract should consider symptoms of abdominal pain,hematuria,and imaging of disseminated pelvic tumors in women,especially those with prior history of laparoscopic hysterectomy.Early complete removal of all tumors is the cornerstone to prevent DPL from malignant changes.
