Since some semblance of order was brought out of the existing confusion by Virchow1 in his classification Of tumors composed of nerve elements, many contributions to the study of their pathology have been made. Of this fairly replete literature no small portion has been devoted to the class of tumors, not without their peculiar interest, that are derived from the undifferentiated and differentiated cellular elements. In this group the commonly termed ganglioneuroma has occupied an important place, and a fairly large series of cases has been reported.
In 1870, Loretz2 reported the first authentic case in which the tumor was found in the left thoracic cavity in the angle between the second and third dorsal vertebrae and the ribs. Since that time, sixty odd cases occurring in various parts of the nervous system have been added to the list. Of these a comparatively small number were located in
