Completely aborted uterine leiomyosarcoma in the puerperium.

A patient passed a large tissue mass at home on postpartum day 1. Pathologic examination demonstrated leiomyosarcoma. A total abdominal hysterectomy was performed, which demonstrated residual disease. All tissue passed in the puerperium should be evaluated to ensure that significant pathologic conditions are not overlooked. Conservative management of leiomyosarcomas is controversial.
