Leiomyosarcoma of cervical stump following subtotal hysterectomy: a case report and review of literature

Background: Leiomyosarcoma that arises in the uterine cervix stump after subtotal hysterectomy is exceedingly rare. Only one case has been documented. The authors report an unusual case of leiomyosarcoma that arose in the cervix stump. Case presentation: A 46-year-old female presented with a one-month history of vaginal bleeding. Vaginal and ultrasonography examination revealed a mass in the cervix. The patient underwent radical resection of the cervix, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy. Chemotherapy and radiotherapy was given after the operation. The patient suffered from severe menopausal symptoms and received hormone replacement therapy. She eventually committed suicide. Conclusion: Given the rarity of cases of leiomyosarcoma of cervical stump, its proper treatment remains to be determined. In dealing with benign uterus diseases, we should pay adequate attention in retaining the cervix. If the cervix is retained, patients require appropriate follow-up. The authors hope that this work will benefit the fields of gynecology and oncology.
