Many types of dermatitis

Dermatitis — an inflammation of the skin — usually appears as swollen, red and itchy skin. It has many causes and occurs in many forms, including contact dermatitis and atopic dermatitis. Dermatitis isn't life-threatening or contagious, but it can be uncomfortable or even painful.

Depending on the type, dermatitis may clear within a few weeks without treatment, or it may require medical attention and a long-term treatment program.
