Abstract
IntroductionPrimary vaginal leiomyosarcomas are uncommon, especially those growing outside the vagina.Out of all malignant vaginal neoplasms, leiomyosarcomas account for about 2%. Reports in the literature mostly concern the pathology of these tumors; few reports have been published that discuss how to surgically remove them.Case presentationA 69-year-old Chinese woman presented with a mass in her buttocks that had been present for more than four months. Computed tomography demonstrated a mass of approximately 12.0×9.5×8.0cm in her retroperitoneal space. We resected the tumor via a posterior incision, and resected part of her sacrum and coccyx. The resected tumor was diagnosed by its pathological features as a leiomyosarcoma. Our patient received adjuvant chemotherapy after surgery. She was free of disease at a one-year follow-up and her general condition is good.ConclusionsWe report a rare case of a primary vaginal leiomyosarcoma that was resected through an approach that has not, to the best of our knowledge, been previously reported. This case report adds valuable knowledge to the sparse available literature on the surgical treatment of vaginal leiomyosarcomas.

Summary
There is no clear preoperative diagnostic criteria for vaginal leiomyosarcomas; diagnosis should be made based on their immunohistochemical features. The gold standard for diagnosis is histology [8]. Primary vaginal sarcoma constitute about 2% of all malignant vaginal lesions, with leiomyosarcoma being the most common in adult women. Surgeons should choose the suitable surgical approach according to the location of the leiomyosarcoma. Consent Written informed consent was obtained from our patient for publication of this case report and any accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal. Authors’ contributions ZX, RYZ, and JL performed the histological examination of the tumor and were major contributors to the writing of the manuscript. All authors read and approved the final manuscript
