Slide show: Types of dermatitis
Common signs and symptoms of stasis dermatitis include:
- Thickened, discolored (reddish) skin on the ankles or shins
- Open sores, oozing and crusting
Stasis dermatitis occurs when varicose veins or other circulatory conditions cause fluids to build up in the lower legs. The swelling produces pressure beneath the skin and prevents adequate blood and oxygen from reaching the skin.
Allergic contact dermatitis
Common signs and symptoms of allergic contact dermatitis include:
- Red rash or bumps
- Blisters, draining fluid and crusting
- Itching and swelling
Allergic contact dermatitis results from direct contact with substances called allergens. It usually affects only the area that came into contact with the allergen. Common allergens include costume jewelry, perfume, cosmetics, hair dyes and poison ivy.
Common signs and symptoms of atopic dermatitis (eczema) include:
- Itching, which may be severe, and raw skin from scratching
- Small, raised bumps, which may leak fluid and crust over when scratched
- Red, leathery, cracked or scaly patches on the skin
Most often, atopic dermatitis occurs in the folds of the elbows, behind the knees and the front of the neck. It tends to flare periodically and then subside for a time, even up to several years. The exact cause of this skin disorder is unknown but is often seen in those with a personal or strong family history of asthma or allergic rhinitis (hay fever).
Irritant contact dermatitis
Common signs and symptoms of irritant contact dermatitis include:
- Red rash or bumps, usually limited to the exposed area
- Burning, stinging or itching, which may be severe
- Dry, red patches, which may resemble a burn
Irritant contact dermatitis develops when your skin comes into contact with an irritating substance. Some people react to strong irritants after just one exposure. Others may develop a skin reaction after repeated contact with even mild irritants. Common irritants include solvents, bleach, soap and cosmetics.
Common signs and symptoms of neurodermatitis (lichen simplex chronicus) include:
- Itchy skin in a single, limited area
- Leathery or scaly patches of skin
- A raised, rough patch that is red or darker than the rest of your skin
Neurodermatitis occurs because of repeated scratching. It typically occurs as a single patch on the head, wrist, forearm or ankle.
With perioral dermatitis, small red, pus-filled bumps appear around the mouth. It can also affect the skin around the nose, cheeks and eyes. The exact cause of perioral dermatitis is unknown, but misuse or overuse of corticosteroid inhalers, nasal sprays and creams may play a role.
Common signs and symptoms of seborrheic (seb-o-REE-ik) dermatitis include:
- Yellowish scales or crust on the scalp, ears, face or other parts of the body
- Red skin
Seborrheic dermatitis is often found on oily areas of the body, such as the scalp, face and chest. It can also appear on the scalp as stubborn, itchy dandruff. For infants, it's known as cradle cap.
