title: [Fibrillar structures in poorly differentiated human soft tissue sarcomas].
abstract: Electron-microscopy examination of 13 soft tissue tumors in human subjects has revealed in four of them, diagnosed histologically as polymorphous-cellular sarcoma, fibrosarcoma, monophase and biphase synovioma, the ultrastructural features allowing them to be classified as rhabdomyosarcomas.
