Abstract
Recently, we had an opportunity to perform the wide block resection of the affected bone in three cases of chondrosarcoma originated in the scapula and pelvis.
In these three cases, it was found that the histological findings were well differentiated.
Concernning to the case originating in the scapula, we succeeded in the total resection of the tumor including the sourounding muscles. There are no evidence of local recurrence and shoulder joint retains moderate range in motion.
Concernning to the case originating in the pubis and ischium proliferating of the tumor in the pelvic cavity and adhesion to the intra-pelvic organs were remarkably seen. And, it was thought that total resection of the tumor was difficult.
So that, post-operative Tele-Cobalt irradiation therapy is now being performed.
Cocernning to the case originating in the iliac bone, the iliac wing was resected including the affected area. And, we could recognize several cartilage foci on the cut surface. It is suggested that the tumor is a secondary chondrosarcoma caused by the malignant change of the cartilage foci. So that, it is thought we should look out for malignant change of the remainning cartilage foci.
