When she re-ported to me for treatment she had a greatdeal of scar tissue about the angle of thejaw, under the ear, an ulcerating epithe-lioma about two inches in diameter, withan induration, apparently malignant, ex-tending about two inches further upwardinto the scalp. The whole area was de-stroyed by electro-coagulation togetherwith about twenty-five small keratoses onthe face. The large ulcer was then treatedby roentgen rays February 13, March 19,April 14, and Alay 21, at which time thewound was healed by granulations and thescar tissue appeared to be healthy. It has ray treatment given in small doses andscattered over such a long period of timethat the cells had, in part, developed aresistance to the rays and were probably. Fig. 10. Epithelioma IX Front OF THE Ear Partial-ly Healed by Long Roentgen Ray Treatment,THEN Taking on Active Growth. Destroyed byElectro-coagulation, Followed by Deep Roent-genotherapy. Healed. Roentgenotherapy in the Treatment of MaHgnant Disease protected more or less by scar tissue. Inaddition to this the scar tissue, and eventhe other tissue round about the lesion,had lost its power of repair. In additionto this I have found that when theseepitheliomata extend up into the subcu-taneous tissues of the scalp they do notrespond readily to roentgen ray treatment,but by combining treatment in this wa}success has been made of what would other-wise have been a failure. Case ii.—(Fig. ii.) Air. H. L. Age by Dr. M. B. Hartzel, October 9,1916. The patient had been treated byroentgen rays for four years for epitheliomaof the nose. For a time the disease seemedto have nearly disappeared, but contin
