Five mesenchymal chondrosarcomas of the bones, soft tissues and the orbit were subjected to histological and electronmicroscopic examination. In all instances the authors found in addition to the differentiated cartilaginous component extensive areas formed by round or spindle-shaped non-differentiated mesenchymal elements which on electron microscopic examination had a striking resemblance with Ewing's Sarcoma cells or resembled fibroblasts. The vascular portions present in all examined tumours reminded of the structure of a haemangiopericytoma. Osteoplasia found in soft tissue tumours had a non-tumourous character.
