Dermatographism is a common, benign skin condition. People who have this condition develop welts or a localized hive-like reaction when they scratch their skin. It can also happen when the skin is exposed to pressure or rubbing. This condition is also called skin writing, dermographia, or dermatographic urticaria. Dermatographism is most likely caused by an inappropriate release of histamine in the absence of a typical immune signal. The red welts and hives are caused by the local effects of histamine. A person with dermatographism may also have an allergy to an external substance.

The condition manifests as an allergic-like reaction, causing a warm red wheal to appear on the skin. As it is often the result of scratches, involving contact with other materials, it can be confused with an allergic reaction, when in fact it is the act of being scratched that causes a wheal to appear. These wheals are a subset of urticaria hives , and appear within minutes, in some cases accompanied by itching. The first outbreak of urticaria can lead to other reactions on body parts not directly stimulated, scraped, or scratched. In a normal case, the swelling will decrease without treatment within 1530 minutes, but, in extreme cases, itchy red welts may last anywhere from a few hours to days.
