Synopsis

Dermographism is an abnormal wheal and flare reaction in the skin induced by pressure, which develops over minutes and is usually asymptomatic, although some forms are associated with pruritus. Inadvertent stroking or rubbing of the skin will result in corresponding linear wheals. The cause of dermographism is unknown, but clinically it appears similar to urticaria and is seen more frequently in patients with urticaria and atopic dermatitis.
