Contact urticaria

Abstract

Core Messages: Contact urticaria is defined as wheals following contact of substances with the skin. The etiology of contact urticaria can be nonimmunologic or immunologic. Common inducers of nonimmunologic contact urticaria are plants, animals, and direct histamine liberators e.g., spices, fragrances, or drugs. The majority of immunologic contact urticaria cases are IgE-mediated. Common inducers of allergic contact urticaria are animal products, plants, foods, and drugs. © 2010 Springer-Verlag Berlin Heidelberg.
