Urticaria is characterised by very itchy weals (hives), with or without surrounding erythematous flares. The name urticaria is derived from the common European stinging nettle Urtica dioica. Urticaria can be acute or chronic, spontaneous or inducible. A weal (or wheal) is a superficial skin-coloured or pale skin swelling, usually surrounded by erythema that lasts anything from a few minutes to 24 hours. Urticaria can co-exist with angioedema which is a deeper swelling within the skin or mucous membranes. Classification of urticaria Urticaria is classified according to its duration. Classification of urticaria Chronic inducible urticaria includes: Dermographism Cold urticaria Cholinergic urticaria Contact urticaria Delayed pressure urticaria Solar urticaria Heat urticaria Vibratory urticaria Vibratory angioedema Aquagenic urticaria Urticaria and angioedema
