Leiomyosarcoma with Unusual Macroscopic Features: A Case Report

Uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. Leiomyosarcoma (LMS) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. Herein, we present a case of LMS with unusual macroscopic features. The patient was a 61-year-old woman with LMS, which consisted of a large cystic mass (88×136 mm), containing six liters of brownish fluid on the right side of the pelvis and abdomen. The fundus of the uterus was ruptured by the solid part of the tumor. For treatment, total hysterectomy, salpingo-oophorectomy and the optimal resection of tumoral parts were carried out. Overall, the distinctive biological behavior and poor overall survival of uterine sarcoma challenge the post-operative management of this tumor. According to the one-year follow-up, the patient was disease-free. Unfortunately, no further information is at hand beyond this period.
