What are the different types of eczema?

'Eczema' is the collective term for any type of dermatitis that is itchy and there are seven main types. Here is a comprehensive list of eczema types, the various symptoms to look for and your best treatment options.

 

Atopic eczema, atopic dermatitis

Atopic eczema, also known as atopic dermatitis, is eczema with one or more allergies present (atopic = allergy). Atopic is the most prevalent form of eczema and is common in children although it can occur at any age. Triggers of atopic eczema include:

  • allergic reactions and food sensitivities,
  • skin infection,
  • nutritional deficiencies,
  • diet high in acid-forming foods, 
  • soaps and detergents,
  • environmental sensitivities, and
  • stress
Treatment options for atopic eczema include allergy testing, avoiding triggers and making dietary changes to prevent flare ups. See Itchy Dozen Worst Foods for Eczema for diet tips. 

    Asteototic eczema, eczema cracquelée 

    Asteototic eczema, also known as “eczema cracquelée”, mostly affects people over the age of 60. It is described as "cracked porcelain" as the skin appears dry and cracked in a "crazy pavement" pattern (or like a dried up river bed). The irregular scaling of the skin, particularly seen on the extremities of the arms and legs, can also have superficial bleeding fissures as the skin splits from being excessively dry. The inflammation can occur along with asymmetric leg edema. 

    Asteototic eczema is associated with:

    • ageing, excessively dry skin, malnutrition and nutritional deficiencies, particularly the B group vitamins and essential fatty acids,
    • use of soaps and detergents (occurring along with contact dermatitis), and
    • use of corticosteroid therapy (topical steroid creams), and can occur after discontinuation of use 
    Treatment options for asteototic eczema include avoiding soaps (avoid body/hand washes that contain sulfates), using sensitive skincare products and improving nutrition in the diet to correct deficiencies and promote healthy blood-flow to the skin. Essential fatty acids are important in the diet. See Itchy Dozen Worst Foods for Eczema or our blog for diet tips. 

        Contact dermatitis, irritant hand eczema

        Contact dermatitis, also known as irritant hand eczema, is the development of skin inflammation by direct contact of the skin, such as from soaps or chemicals. It can also occur via an allergic reaction which is known as allergic hand eczema. Symptoms range from mild dryness and red skin, to very painful and raw skin, peeling and/or a "burnt skin" appearance. 

        Common triggers include:

        • contact with chemicals,
        • sensitivity to soaps and detergents,
        • stress (very common cause of hand symptoms),
        • contact with bleach,
        • latex in rubber gloves, and
        • nickel in cheap jewellery

        and in some instances it can be triggered by

        • cold wind, and
        • raw foods

        Contact dermatitis is common in people who work with chemicals and rough materials, such as hairdressers, metal workers, construction workers and cleaners, and people who wash their hands often including chefs and nurses. 

        Treatment options for contact dermatitis include avoiding triggers, avoid hand/body washes that contain soap or sulfates and reduce stress.

        Discoid eczema/dermatitis, nummular eczema

           

        Discoid eczema, also known as nummular eczema, presents with coin-shaped areas of skin inflammation and may appear scattered on the body. Often seen in adults with dry skin and less commonly in adolescents and children. Discoid eczema may occur in conjunction with atopic eczema/dermatitis.

        Symptoms include slightly bumpy coin-shaped discs, usually on the lower legs, arms or trunk. Within a week the patches may begin to ooze, and the crusts are itchy, scaly and can become infected. The centre of the disc soon clears but the skin remains dry and it often flakes.

        Although discoid eczema can be triggered by many factors, the most common triggers include a predisposition to dry skin and eczema, plus contact with:

        • perfumes,
        • chemicals and cleaning products,
        • soaps, spray deodorants and detergents
        Treatment options for discoid eczema include avoiding perfumes (and "fragrance" ingredients), avoid regular soaps and washes (use natural hand/body washes that are sulfate free), use sensitive skincare products and follow a low-chemical diet and improve nutrition to prevent chemical sensitivity.

          Gravitational eczema, varicose eczema, stasis eczema

          Gravitational eczema (also called varicose eczema or stasis eczema), is seen on the legs, particularly around the ankles in those who have had long-standing varicose veins for many years. Not only does eczema appear, the skin can also darken and may eventually ulcerate if left untreated. Other symptoms include weeping and crusting and varicose leg ulcers (small holes in the skin which can worsen and become very sore, requiring urgent medical treatment).

          Varicose eczema is common later in life and is more common in women than men. If you have poor circulation, varicose veins, are overweight or obese, or if you have previously had a blood clot, you have an increased risk of developing varicose eczema. Poor circulation and varicose veins (the main contributing factors) can be caused by:

          • weakened blood vessels caused by poor diet (deficiencies in minerals, including silicon and low intake of antioxidants, to name a few),
          • malnutrition,
          • ageing which causes poor digestion of foods (and poor absorption of nutrients)
          • sedentary lifestyle, and 
          • being overweight or obese
          Treatment options for varicose eczema include seeing your doctor, avoiding soaps (avoid body/hand washes that contain sulfates), using sensitive skincare products and improving nutrition in the diet to correct deficiencies and promote healthy blood-flow to the skin. Strengthening vein health is important and silica supplementation may help. Speak with a nutritionist regarding nutrition for vein health. See Itchy Dozen Worst Foods for Eczema or our blog for diet tips. 

            Pompholyx eczema,  dyshidrotic eczema (dyshidrotic dermatitis)

            Pompholyx eczema, also called dyshidrotic eczema, presents with blistering on the hands and feet. The blisters can break and weep, and the skin is inflamed and may be very itchy. Peeling can also occur when the skin is very dry. The sides of fingers, palms of hands and soles of feet are affected, although this form of eczema can present with other types of eczema elsewhere on the body. Contributing factors include:

            • emotional tension or stress,
            • sensitivity to metal compounds (nickel, cobalt, chromate), and
            • exposure to heat and sweating can also aggravate this form of eczema.

            Pompholyx eczema accounts for 5-20% of all cases of hand eczema. More information on pompholyx/dyshidrotic eczema can be found here.

            Seborrhoeic dermatitis

            Seborrheic (pronounced seb-or-a-ik) dermatitis is a flaking, itchy skin rash which appears on areas of the skin that have large numbers of oil (sebaceous) glands. It’s also known as seborrheic eczema and usually first appears on the scalp as dandruff. A yeast called pityrosporum ovale (also known as malassezia) is found on the skin of people with seborrhoeic eczema, and is a contributing factor.  More information on seborrheic dermatitis can be found here. 

            If you have symptoms of eczema and you have not seen a doctor, visit your doctor or local skin specialist for a formal diagnosis.
