WHAT IS DERMOGRAPHISM?

Dermographism is an exaggerated wealing tendency when the skin is stroked. It is the commonest form of physical urticaria. It is also called dermatographism, dermatographia and dermatographic urticaria.

In 25-50% of normal people firm stroking of the skin produces first a white line, then a red line, then slight swelling down the line of the stroke, and a mild red flare in the surrounding skin. In 5% of the population this response is exaggerated enough to be called dermographism.

ETIOLOGY OF DERMOGRAPHISM?

The exact cause of dermatographism is unknown. Histamine is the main chemical released by mast cells when the skin is stroked, but other chemical mediators may also be involved.

CLINICAL FEATURES

Dermographism can appear at any age.

Patients with dermographism are usually otherwise healthy.

Dermographism may last for a couple of hours. In many patients, however,the wealing is reduced to a degree which no longer causes significant symptoms.

TREATMENT

Antihistamines often give good relief from symptoms. The new non-sedating ones are generally preferred.

You should also avoid hot baths or showers,rough towelling down and rough clothing against the skin.
