Dermatitis is a general term that describes an inflammation of the skin. There are different types of dermatitis, including seborrheic dermatitis and atopic dermatitis (eczema). Although the disorder can have many causes and occur in many forms, it usually involves swollen, reddened, and itchy skin.

There are several types of dermatitis, including

  • Contact dermatitis, a rash that results from either repeated contact with irritants or contact with allergy-producing substances, such as poison ivy.
  • Neurodermatitis, a chronic itchy skin condition localized to certain areas of the skin.
  • Seborrheic dermatitis, a common scalp and facial condition that often causes dandruff.
  • Stasis dermatitis, a skin condition that’s caused by a buildup of fluid under the skin of the legs.
  • Atopic dermatitis, more commonly known as just eczema or atopic eczema, is a chronic itchy rash that tends to come and go.
  • Perioral dermatitis, a bumpy rash around the mouth.

Each has distinct signs and symptoms. Common signs and symptoms include:

  • Redness
  • Swelling
  • Itching
  • Skin lesions
