Specific hyposensitization is rarely advocated for the treatment of atopic dermatitis. Good results have been obtained in fifteen mainly adolescent and adult patients selected from over 3,000 patients with atopic dermatitis. Criteria included a history of exacerbations of the dermatitis after exposure to the antigen, an airborne antigen which could not be avoided, a rather distinctive clinical picture and symptoms bad enough to warrant the considerable difficulties involved.
