Skin rashes can occur from a variety of factors, including infections, heat, allergens, immune system disorders and medications. One of the most common skin disorders that causes a rash is atopic dermatitis (ay-TOP-ik dur-muh-TI-tis), also known as eczema.

Atopic dermatitis is an ongoing (chronic) condition that makes skin red and itchy. Most often it appears as patches on the hands, feet, ankles, neck, upper body and limbs. It tends to flare up periodically and then subside for a time.

At-home interventions, such as avoiding harsher soaps and detergents or other irritants and applying creams or lotions, can lessen symptoms and reduce the risk of flare-ups. Medicated anti-itch creams or ointments also can lessen symptoms.
