Hello, dermatoglyphic is also called artificial urticaria. There are two common dermatoglyphics. One is called simple dermatoglyphics, that is, after scratching the skin with nails and other things, a series of rashes appear, but patients do not feel itchy and other discomfort. This rash usually disappears after 10 ~ 15 minutes. This is a physiological abnormal physical reaction. Another dermatoglyphics is an allergic reaction caused by physical stimulation of the skin. When local skin cells are scratched or rubbed by blunt objects, mast cells of human body release histamine and other active substances, which can dilate skin capillaries and make plasma ooze from blood vessels to dermis, so skin itching and wheal consistent with skin irritation appear.

If it is simple skin, it generally does not need treatment. For symptomatic skin scratches, we must first find the cause and remove the cause as much as possible. For example, patients who are using penicillin should stop using penicillin immediately; People infected with bacteria should be treated with anti-infection; People infected with tinea pedis and other fungi can receive antifungal treatment. Secondly, antihistamines, such as chlorpheniramine and antongding, can be used, which has certain curative effect. In addition, some drugs such as vitamin C and calcium can be used to reduce the permeability of blood vessel wall. It is worth noting that patients with skin abrasions should not be treated with penicillin when they suffer from other infectious diseases.

I hope I can help you!
