In the healed bone cyst of my ownobservation, in which the swelling had been present twenty-two years, from the vague history of the patient one wouldinfer that the first symptoms of the trouble were signs ofinfection. These findings demonstrate how insidious the pathologicalprocess in the medullary cavity may be until a slight traumaproduces a fracture. Even then the fracture heals, and thepatient may not return under observation for years. There-fore, it may be fair to conclude that in all of these cases theonly prominent etiological factor is a trauma, but we have no Fig. Pathol. \o. 7374.
