Abstract

Dermographia is commonly demonstrated by stroking the skin with a blunt instrument. The response is a local swelling and itching, and the itching is increased by anything that will cause vasodilation in the skin. Emotions sometimes contribute to the vasodilation. The reaction is sometimes immediate, sometimes delayed. Its relation to urticaria has been difficult to explain. The most effective remedies are the antihistamines, the choice and dosage being determined by the individual needs and tolerance of the patient.
