Multiple osteochondromatosis is a hereditary disorder affecting the endochondral skeleton during period of growth. We have studied a family which have multiple osteochondromatosis clinically and radiologically. In this family, eight of ten members could traceable, have the lesions of multiple osteochondromatosis. The most common site of the lesions was in femur, and the next common site was in tibia, especially, near the knee joint.

Rhabdomyosarcoma is highly malignant soft tissue tumor which arise within skeletal muscles of the body. It makes up about 10 to 15 percent of sarcomas of the soft somatic tissues. Approximately two third of them originate in the muscles of the extremties, usually the legs. We have experienced two cases of rhabdomyosarcoma, the one arised within left forearm skeletal muscles and the other, within right calf muscles. The former was pleomorphic type, the latter was embryonal type in histological study.
