To The Editor.—
In his excellent editorial in the June, 1959, issue of the A.M.A. Archives of Dermatology, Dr. Michelson states very correctly, "One of the more prominent deficiencies is our inability accurately and completely to outline the boundaries of a cancer and its ramifications." He makes no mention of the chemosurgery technique devised by Mohs and his co-workers and further modified by Allington et al.In theory, at least, the Mohs' technique corrects the deficiency pointed out by Dr. Michelson.Very truly yours,
