Myxoma of bone. Report of three cases.

Three cases of myxomas of bone are presented. No similar tumor, except in bones of the jaw, was found in a study of more than 6,000 bone tumors in the files of the Mayo Clinic to Jan. 1, 1976. These three tumors were found in a series of about 5,000 lesions of bone in patients sent to the Mayo Clinic for consultation. All three of these tumors affected the femur. Care was taken to exclude lesions such as chondrosarcoma, fibrosarcoma, chondromyxoid fibroma, and ganglia of bone, all of which may contain prominently myxoid zones.
