Contact urticaria to parabens
Abstract
Contact urticaria developed in a patient after topical application of paraben-containing compounds. Positive open patch test results and a positive passive transfer (Prausnitz-Küstner reaction) test demonstrated an immunologic mechanism for the patient's skin reaction. The importance of parabens to contact urticaria is described.
