Uterine leiomyosarcoma - right on time

Abstract Uterine leiomyosarcomas, although rare, are the most frequent histological type of uterine sarcomas, and have a poor prognosis even when diagnosed in early stages. More often they present with abnormal uterine bleeding, pelvic mass and/or pelvic pain, making the differential diagnosis with uterine leiomyomas. Due to its rarity and aggressiveness, there is no consensus regarding the treatment algorithm. We describe the case of a woman who presented a spontaneous rupture of leiomyosarcoma, a rare manifestation with few cases described in the literature.
