To the Editor.—
Scabies is generally treated in the United States with the topical application of gamma benzene hexachloride cream or lotion, crotamiton cream, or 6% to 10% precipitated sulfur in petrolatum. The gamma benzene hexachloride lotion or cream and the crotamiton cream are generally applied from the chin down and are left on, in the case of gamma benzene hexachloride, from 12 to 24 hours, and in the case of crotamiton, for 24 hours. The application of crotamiton may be repeated 24 hours later, while gamma benzene hexachloride is generally not repeated unless necessary, and then not until one week has elapsed. The 6% precipitated sulfur in petrolatum is generally applied over the entire body surface nightly for three nights. I would like to report two cases of scabies that did not respond to treatment with crotamiton.
Report of Cases.—Case 1.—
