L20.9: Atopic dermatitis, unspecified
Your skin has been inflamed and very itchy for a long time.
This disorder involves the immune system overreacting to substances in the environment that are actually harmless. These may be animal hairs or foods, for example. The skin gets inflamed as a result. This makes the skin dry and susceptible to germs.
Initially, the skin is usually red and swollen. Blisters or weeping open wounds occur. Then yellowish crusts often form. If the skin is damaged for a long time, it gets thick and cracked. The skin may also be flaky. Because the skin is usually very itchy, you often scratch yourself.
This skin disorder is usually congenital, which means you were born with it. Several family members are usually affected. The skin disorder may be a lifelong condition. But it may also improve after childhood. The symptoms can vary in their severity. Stress, or contact with germs, for example, can make the condition worse. There may also sometimes be psychological effects.
