Dermatographism |
Dermatographism, also known as dermagraphism, simply translates "writing on the skin”. It is a very common localized hive reaction, affecting approximately 2-5% of the general population. This condition is characterized by the abrupt onset of welts and hives where the skin is exposed to pressure, scratching, itching or stroking. Dermatographism is frequently diagnosed incidentally, especially in relation to other skin disorders like eczema. The skin lesions are believed to be the result of an inappropriate release of histamine in the absence of a typical immune signal. Histamine causes the exaggerated response leading to red welts and hives.
Diagnosis is usually based on clinical findings and corresponding history. If the diagnosis is in question, rubbing the skin with a tongue depressor can be used to elicit a reaction. In addition, a spring-loaded instrument, known as a dermographometer, can be used to measure skin sensitivity in response to a preset amount of pressure. Treatment may be achieved with common dermatologic therapies. Over the counter anti-histamines can block the inappropriate histamine response while adequate skin care and routine moisturizing can improve dryness and itching. Finally cromolyn, a prescription medication, is used to stabilize the cell membrane responsible for the release of histamine and has a similar effect as anti-histamines.
