Dermatitis Prevention Types of Dermatitis: peri-oral dermatitis, peri-oral refers to the facial area around the mouth while dermatitis pertains to inflammation, redness or irritation of the skin. In addition, there are usually small red bumps or even pus bumps and mild peeling as the skin is extremely aggravated. Seborrheic dermatitis is a non-contagious condition that causes flaking and redness of the skin. It occurs when there is inflammation in areas of the skin where sebaceous (skin oil) glands are concentrated. It usually affects the scalp, but can also affect other parts of the body, such as eyebrows, eyelids, the folds of the nose, lips, behind or inside the ears, in the external ear, the forehead and the chin and the skin of the trunk, particularly around the navel, in the skin folds under the arms, in the groin, or under the breasts. Seborrheic dermatitis appears to run in families. The most common form of eczema is atopic dermatitis. Atopic dermatitis is marked by dryness, thickening, excoriation, and even scarring. This chronic condition is not contagious; the cause is hereditary and usually begins in infancy as a rash on the scalp, face or upper extremities of the baby. Infantile seborrheic dermatitis, also called cradle cap affects the face, scalp, and upper extremities and is often associated with food consumption (cheese, egg whites, wheat, or nuts are common causes of infantile seborrheic eczema). Other triggers that can cause baby eczema include soaps, laundry etergents, fabric softeners, wool, and polyester or blended fabrics. Contact dermatitis is an inflammatory response by the skin to an outside allergen or irritant. Substances that cause contact dermatitis include household items, clothing, cosmetics, and plants. The types of substance that cause the symptoms to appear can further define contact dermatitis. A substance that has a direct toxic effect or exposure to an irritant produces irritant contact dermatitis and a skin reaction can occur immediately or gradually after repeat exposure. Allergic contact dermatitis will trigger an immunologic response that causes inflammation called a skin allergy. Itching and burning are common symptoms in both types of contact dermatitis. Typically the symptoms of contact dermatitis include redness, swelling and oozing. If left untreated, contact dermatitis can result in dry, thickened, cracked skin. The webs of the fingers, back of the hands and forearms are common sites of contact. Local contact with an allergen followed by exposure to ultraviolet radiation (sunlight) can cause photoallergic dermatitis. The symptoms of dyshidrotic dermatitis include itching of the hands and feet, which can cause a sudden onset of blisters. Symptoms including burning pain or itching may be experienced before blisters appear. Dyshidrotic dermatitis is a form of hand dermatitis, which is more common in women and starts on the sides of the fingers as itchy little bumps and then develops into a rash. Pustular dermatitis may cause blister-like lesions of noninfectious pustules (yellow pus spots) and intense scaling usually found on the hands or feet. They tend to become red and scaly and may crack. Hyperlinearity atopic dermatitis occurs in the palms and results in increased numbers and depth of the lines on the palms of the hands with little redness. Xerotic eczema, winter itch, or asteatotic eczema occurs in winter and in the elderly on the legs, arms, and hands. It is characterized by dry, cracked, fissured skin and redness. Stasis dermatitis is a rash of the lower legs which is due to poor return of blood to the heart. Usually the inner leg is more involved than the outer lower leg. Sometimes the rash breaks down into a sore resulting in a stasis ulcer. Nummular dermatitis is a ringworm-like rash of circular, itchy, scaling patches, widespread on the arms and legs but may also be found on the trunk and buttocks. Nummular eczema is most common in older people with very dry skin. Learn more about the dual effect of rosacea and dermatitis at The International Rosacea Foundation.
