Acute and Chronic Urticaria

  • Beate M. Czarnetzki

Abstract

Urticaria is defined by the appearance of wheals (hives or individual urticae) of any size and configuration on any part of the skin. The wheals consist of a circumscribed, slightly elevated, erythematous, usually pruritic, edematous swelling of the upper dermal tissue which disappears within minutes to hours, leaving a basically unaltered, normal appearing skin (restauratio ad integrum). Similarly transient, erythematous swellings of the deeper cutaneous and the subcutaneous tissue are called angioedema and appear in about 50 % of patients in association with ordinary urticaria (see Chapter 4, p. 47).
