Abstract

Uterine leiomyosarcoma is a rare malignant neoplasm, with a very poor prognosis and higher prevalence in pre- and peri-menopause. It accounts for only 1-2% of uterine malignancies. We report the case of a 75-year-old postmenopausal woman, who presented a large abdominal mass, compatible with uterine leiomyoma. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy obtaining a surgical piece weighing 9820g. The diagnosis of Uterine leiomyosarcoma is made by histopathological examination after surgery.
This clinical case demonstrates that it is essential to bear in mind a possible diagnosis of malignancy to reduce the prevalence of occult Uterine leiomyosarcoma.
