We report 3 patients with a second bone involved with osteosarcoma. They were found among approximately 200 cases of limb-sparing surgery with chemotherapy. 1 patient had the unusual finding of a positive MRI scan with all other routine tests negative. The first and then the second bone tumor were successfully removed with limb-sparing surgery. All 3 patients are doing well, with no evidence of disease.
