Recurrent extraperitoneal low grade leiomyosarcoma with unusual localization.

Primary extragenital leiomyosarcoma is rarely found in pelvic localization. A 33-year-old multiparous woman who had recurrent low-grade leiomyosarcoma presented with the complaints of dyspareunia, pelvic pain and gait disturbance. Her past medical history revealed she had been subjected to maximal excision of a paravaginal mass by using vaginal and suprapubic transverse incision three years before. The pathology report showed that she had leiomyoma. Three years after the initial surgery, a paravaginal fixed mass was observed at the initial tumor bed and removed by the perineal approach. The histological examination of the specimen revealed a low grade leiomyosarcoma. She was discharged from hospital without any complications.
