Extraosseous Osteogenic Sarcoma

Abstract
Nine cases of extraosseous osteogenic sarcoma were seen at M. D. Anderson Hospital in Houston. Most of these tumors occurred in the lower extremities of middleaged people. Local excision was performed in seven patients, and in all cases there was local recurrence followed by death. In hopes of improving prognosis, amputation or disarticulation should be considered as possibly more effective than local excision.
