L20-L30: Dermatitis and eczema
L20: Atopic dermatitis
Atopic dermatitis, also known as eczema, is a common condition that affects the skin, causing it to become dry, itchy and inflamed. It usually begins in early childhood and often progresses or goes into remission as one grows older. It's characterized by intense itching and recurrent red skin rashes that typically occur on the folds of the arms, behind the knees, or on the front of the neck. Although the exact cause of atopic dermatitis is unknown, the condition is believed to be linked to an overactive immune system and is often seen in individuals with a history of allergies or asthma. Environmental factors such as weather changes and exposure to certain irritants can also trigger or exacerbate the condition. While atopic dermatitis is not contagious, it does have a genetic component and is more likely to occur in individuals with a family history of the condition.
