title: Contact urticaria and its mechanisms.
abstract: This paper reviews the syndrome of contact urticaria in terms of current knowledge regarding pathophysiological mechanisms. The three mechanistic categories into which contact urticants are grouped include: (1) immunological contact urticaria, (2) non-immunological contact urticaria and (3) uncertain-mechanism-mediated contact urticaria. Within this schema, the clinical manifestations, diagnosis and therapy of contact urticaria are presented.
