Of the 422 primary malignant tumors of bone and soft tissue treated at one institution between 1968 and 1988, the 29 found in the upper extremity in children are reviewed. In the latter group, there were 13 patients with osteosarcoma; one was lost to follow-up shortly after diagnosis, one was alive and disease free four years after surgery, two are currently being followed, and nine are dead. All of the four patients with Ewing's sarcoma died. Three patients had chondrosarcoma; one was lost to follow-up after surgery, and the other two were disease free at four and 14 years' follow-up. Two of the nine patients with soft-tissue sarcomas died as a result of their tumors.
