Synopsis

Dermographism is the most common form of physical urticaria and manifests as an exaggerated wheal and flare reaction of the skin induced by pressure. In dermographism, inadvertent stroking or rubbing of the skin will result in corresponding linear wheals. The wheals usually persist for 15-30 minutes. It is usually asymptomatic, but some forms are associated with pruritus. The exact cause of dermographism is unknown, but clinically it appears similar to urticaria. Agents that are known to cause / exacerbate urticaria also may cause dermographism (eg, angiotensin converting enzyme [ACE] inhibitors).

An increased incidence has been reported during pregnancy and in individuals with Behçet syndrome, thyroid disorders, infections, or atopic dermatitis. It affects approximately 2%-5% of the population and is more common in young adults.
