title: [Contact urticaria. Experimental contribution].
abstract: Contact urticaria is characterized by erythematosus whealing lesions after apposition of particular substances on the skin. Sometimes these substances are able to determine systemic reactions as rhinoconjunctivitis, bronchial asthma, gastrointestinal dysfunction and anaphylactic shock: these symptoms justify the denomination of contact urticaria syndrome. It can be classified as Immunological, not Immunological and Unidentified. Our cases show a sharp prevalence of contact urticaria caused by foods and especially by fruits and vegetables.
