Diseases and Conditions
Dermatitis is a general term that describes an inflammation of the skin. Dermatitis can have many causes and occurs in many forms. It usually involves an itchy rash on swollen, reddened skin.
Skin affected by dermatitis may blister, ooze, develop a crust or flake off. Examples of dermatitis include atopic dermatitis (eczema), dandruff and rashes caused by contact with any of a number of substances, such as poison ivy, soaps and jewelry with nickel in it.
Dermatitis is a common condition that's not contagious, but it can make you feel uncomfortable and self-conscious. A combination of self-care steps and medications can help you treat dermatitis.
