Elkin and Cooper reported 19 cases of large hemangiomas, 3 of which involved various muscles of the chest wall.4 Two of these tumors were completely excised; the third, only partially because of its extent.
Dumbbell tumors of the mediastinum and spinal cord make up a small percentage of all spinal-cord tumors. The great majority of these have their origin in nerve tissue. Heuer studied 64 dumbbell tumors, 43% of which
