Dermatographism - Dermatographic

Dermatographism is a subtype of urticaria. It is also known as dermographism, dermatographic, or dermatographic hives. Urticaria is the official, medical term used for hives. The rest of the article describes dermatographism, its causes, symptoms, and cures in detail.

Dermatographism or dermatographic urticaria is characterized by eruptions and inflammations on the skin when an external offending stimulus comes in contact with the skin. This makes the skin look as if someone has written on it, which is why it is also called skin writing.

Human skin contains certain cells, which are called mast cells to protect it against pathogens. The membranes surrounding these cells are weak for some people. In such cases, when the skin is rubbed or scratched, it will release a substance called histamine, which results in the damage of these membranes that causes rashes and swelling of the skin.

The actual cause for dermatographism is unidentified. The most commonly believed causes include stress and exposure to extreme heat or cold. Several things that can trigger its occurrence include kissing, tight clothing, watches, rings, glasses, and anything that causes pressure or stress to the skin. Even when the skin gets slapped, scratched, or rubbed, eruptions may occur.

It is not a contagious disease and it does not spread from one person to another. In most cases, the eruptions will disappear within some time after the outbreak; therefore, many people do not need treatment for this. However, some patients may experience this condition for their entire lives. Though in most cases, it is not life threatening, there are some cases that may be severe enough to become life threatening. Therefore,  proper treatment is necessary.

Antihistamines can be used to treat patients, which prevent the eruptions from appearing. Acupuncture treatments are also available to treat this condition.  Biodegradable and hypoallergenic soaps are used by many patients to help prevent outbreaks. In addition, patients are advised to avoid bathing in hot water.
