title: Leiomyosarcoma arising from soft tissue tumor of the mediastinum.
abstract: The occurrence of a leiomyosarcoma (LMS) in soft tissue of the mediastinum is rare. We report a 60-year-old woman with an LMS in mediastinal soft tissue who died 8 months after surgical removal. Pathological, immunohistochemical, and electron microscopic features of this rare tumor are described.
