Contact allergy to hydrocortisone and systemic contact dermatitis from prednisolone with tolerance of betamethasone*1

Abstract

Our patient's allergy was undiagnosed for 5 years, and it was not until she was given a cross-reacting corticosteroid, which led to exacerbation of her dermatitis, that her physician suspected corticosteroid allergy. The incorporation of marker molecules for the detection of corticosteroid contact allergy into standard series with two reading occasions, 3 to 4 days apart, is advocated.
