Not a lot of pressure is required to trigger the dermatographism symptoms. Sometimes, simply rubbing the face lightly with a finger will cause the flare-up of a red itchy raised patch of skin. This is very noticeable and can cause embarrassment and stress for the affected individual. Greater amounts of applied pressure to the skin will produce more dramatic dermatographism symptoms.
Objects that create friction on the skin such as tight fitting clothing, wristwatches, belts, and even eye glasses where they contact the skin, can all trigger the dermatographism symptoms.
In 25-50% of people, firm stroking does produce more than the normal amount of skin redness. However, welts are not present and neither is excessive itching. Approximately, 2-5% of individuals will experience the full symptoms of dermatographism. All body surfaces can be affected by this skin condition. The most common body areas to be affected are the trunk of the body (back, chest, abdomen), buttocks, and face. Arms and legs may also be involved, but the scalp and genitalia areas less frequently.
A dermatologist diagnoses the condition by focusing on the key dermatographism symptoms and questioning the patient’s history. The dermatologist uses a wooden tongue depressor and runs it down the patient’s back using mild to moderate force to see if a welt develops within a few minutes. The back is normally used rather than the arms or any other body part because it is more sensitive. The back area of the body tends to be more protected from day-to-day pressure exposure and environmental influences. A dermatographometer or dermographometer, which is simply a spring-loaded stylus can be used in the diagnosis. This instrument applies graded and reproducible pressure to the skin and is mainly used in clinical studies or to diagnose if the dermatographism is mild, moderate, or severe. Dermographism symptoms can appear at any age, but is more common in young adults. Individuals in their 20s or 30s are most often affected.
