Pressure upon the swelling often elicitsthe ijeculiar egg-shell crackling characteristic of thosecouditious in which the bone is greatly expanded andthinned. The general appearance of the disease closelyresembles that of solid tumors of the upper jaw. whichfact has caused surgeons, in a number of instances, toexcise the entire upper jaw unnecesstirily.
