title: [Peripheral vascular leiomyosarcomas. Apropos of 2 cases].
abstract: The authors report here two observations of leiomyosarcomas arising from peripheral blood vessels. The first case occurred in the pedious vein and infiltrated into tarsal bones. The second case was localized into leg muscles' tendons, near the knee. The topographical and histological characteristics of peripheral vascular leiomyosarcomas are noted, and compared, according to the review of literature, with those of the great central blood vessels, and of other classical leiomyosarcomas.
