However, it usually arises in long bones and truncal bones, whereas these tumors are uncommon in the hands and feet. The type are (A) Primary chondrosarcomas arises denovo from bone without any preexisting lesion. (B) Secondary chondrosarcomas when tumor arises from preexisting benign lesions of bone.
