Grade Ⅱ ~ Ⅲ periosteal chondrosarcoma of the performance of the same histological grade Ⅱ ~ Ⅲ peripheral chondrosarcoma and periosteal Ⅲ grade chondrosarcoma are rare.

Periosteal chondrosarcoma is diagnosed by X-ray. Performance is the spherical mass, and sometimes uneven surface, is located at the surface of cortical bone, periosteum or periosteum may be the origin of things. Juxtacortical osteosarcoma with similar, when the periosteal chondrosarcoma located in the distal femur, the bone often located in the rear to the development of popliteal fossa. Periosteal chondrosarcoma showed cartilaginous tumor, and sometimes in the X-ray imaging is not only through CT or MRI examination to clear the line. Tumors often granular, punctate and annular calcification, and occasionally have a vague fascicular Shadow ossification. Below the cortical bone tumors are sometimes complete, sometimes the surface by erosion, the erosion of cortical bone can be blurred, but often the pressure for the butterfly trails, clear and thick border. Around the tumor may have periosteal reaction, resulting in the ossification of the triangle, enveloping the tumor part of the basement.
