Dermatitis

Dermatitis is an inflammation of the skin that may be produced by a variety of causes. Atopic dermatitis (sometimes called eczema) and contact dermatitis (when a specific substance irritates the skin) are two of the most common causes of dermatitis.

Symptoms of dermatitis include very itchy skin and a red rash. Eczema rashes are usually increased in the folds of the arms, bends of the knees and wrists, ankles and face. Contact dermatitis, like poison ivy, usually has a characteristic pattern on exposed areas. An allergist can diagnose and treat both atopic and contact dermatitis, in addition to other less common causes of dermatitis.

Allergens such as dust mites as well as foods may worsen atopic dermatitis. Allergists can diagnose the allergies that are frequently associated with atopic dermatitis and also help determine which substances are causing contact dermatitis. Your allergist can talk to you about how to avoid substances that may make dermatitis worse, as well as the best use of medicines and other options to control the condition.

When to see an allergist:

  • To confirm diagnosis of atopic or contact dermatitis.
  • For a rash that does not respond readily to treatment.
  • If a rash is extensive or severe.
  • To check for allergies contributing to a rash.
  • If there is any concern that food allergy may be present.
