Dermatitis is a general term that describes an inflammation of the skin. There are different types of dermatitis, including seborrheic dermatitis, contact dermatitis and atopic dermatitis (eczema). Though the disorder can have many causes and occur in many forms, it usually involves swollen, reddened and itchy skin. Dermatitis is a common condition that isn’t life threatening or contagious. But, it can make you feel uncomfortable and self-conscious. A combination of self-care steps and medications can help you treat dermatitis.
