Power Morcellation of Unsuspected High-grade Leiomyosarcoma Within an Inflated Containment Bag: 2-year Follow-up.

The diagnosis of an unsuspected leiomyosarcoma after hysterectomy for the treatment of a presumed benign leiomyoma is a rare but highly clinically significant event. In order to facilitate removal of large uterine specimens using a minimally invasive surgical approach, morcellation with extraction in pieces is often performed. In the event of unsuspected malignancy, this may result in abdominal dispersion of the tumor and contribute to poorer survival. In the present article, we report a case of contained power morcellation of an unsuspected high-grade leiomyosarcoma with 2 years of follow-up. Although further study is necessary, this technique may minimize the risk that women undergoing laparoscopic hysterectomy with morcellation have a worse prognosis when diagnosed with an unexpected malignancy.
