title: [Morphology and histogenesis of soft tissue chordoid sarcoma].
abstract: The data of examinations of 6 chordoid-sarcomas of soft tissues which, owing to myxomatosis of the interstitial substance and vesicle-like cells containing glycogen, are similar in structure with skeletal chordoma are presented. It is emphasized that choroidsarcoma, unlike chordoma, has the ultrastructural features of cartilage differentiation: collagenization of the matrix, similarity of some tumour cells to chondrocytes. These data suggest that chordoid-sarcoma is histogenetically associated with rudiments of mesenchyma responsible for cartilage formation.
