Two distinct types of tumors arise from the ears-those having their origin upon the pinnae, which are mostly rodent ulcers, and those arising from within the auditory canal, which grow very rapidly, being of the more malignant type. Heidingsfeld has had a very remarkable case where such a tumor arose from the mastoid region after an operation for an infection of this area. Tumors of the pinna are not often met; the author has seen only one, and Bloodgood reports only three. The rodent ulcer variety should be treated with either the rontgen rays or curette and caustic because of the deformity that must of necessity follow an operation with the knife alone. The deep tumors are probably hopeless from the start, but radical surgery might save a few.
