title: Uterine myxoid leiomyosarcoma within a leiomyoma.
abstract: A case of myxoid leiomyosarcoma of the uterus arising in a leiomyoma is reported. Although the tumor showed very low mitotic activity ranging from zero to 2/10 HPF, the presence of infiltrative pattern of growth and a high MIB-1 index (60% of cells positive) established the diagnosis. Myxoid leiomyosarcoma may arise in leiomyoma.
