Eczema is not contagious. You can’t “catch it” from someone else. While the exact cause of eczema is unknown, researchers do know that people who develop eczema do so because of a combination of genes and environmental triggers. When an irritant or an allergen from outside or inside the body “switches on” the immune system, it produces inflammation. It is this inflammation that causes the symptoms common to most types of eczema.

There are several different types of eczema that you should know about:

• Atopic dermatitis
• Contact dermatitis
• Dyshidrotic eczema
• Nummular eczema
• Seborrheic dermatitis
• Stasis dermatitis

Though there are several distinct types of eczema, it is possible to have more than one type at a time. All types of eczema cause itching and redness, but some may also cause your skin to blister, “weep,” or peel.

It’s important to understand which type you or your child may have and also your symptoms and triggers, so that you can best treat and manage your eczema. But the only way to be sure that you or your child has eczema and which type, is to make an appointment with your doctor.

1. Atopic dermatitis

Atopic dermatitis is a type eczema that is chronic and inflammatory. Though the exact cause of atopic is unknown, it happens when the immune system goes into overdrive in response to an allergen or irritant inside or outside the body. AD usually begins in childhood, often in the first six months of the life. When you or your child have AD, it might improve at times or it may get worse (when you may experience what’s called a “flare”).

Atopic dermatitis is part of what’s called the atopic triad, which includes two other allergic conditions (asthma and hay fever, which is also known as allergic rhinitis). Researchers believe that people who come from families with a history of atopic dermatitis, asthma and/or hay fever are more likely to develop atopic dermatitis themselves.

Some common symptoms of atopic dermatitis:

• Dry, scaly skin
• Redness (erythema)
• Itching
• Cracks behind the ears
• A rash on the cheeks, arms and legs
• Open, crusted or “weepy” sores (usually during flare-ups)

2. Contact dermatitis

Contact dermatitis happens when the skin touches irritating substances or allergens. These make the skin inflamed, causing it to burn, itch and become red. There are several kinds of contact dermatitis but irritant contact dermatitis and allergic contact dermatitis are the most common. Contact dermatitis usually appears on the hands, or parts of the body that touched the irritant/allergen.

The  most common irritants include:

• Solvents
• Industrial chemicals
• Detergents
• Fumes
• Tobacco smoke
• Paints
• Bleach
• Wool
• Acidic Foods
• Astringents
• Skin care products that content alcohol (but not cetyl alcohol)
• Some soaps and fragrances
• Allergens (usually animal dander or pollens)

Symptoms of contact dermatitis include:

• Redness and rash
• Burning or swelling
• Blisters that may weep or crust over

3. Dyshidrotic eczema

Dyshidrotic eczema is a condition that produces small, itchy blisters on the edges of the fingers, toes, palms, and soles of the feet. Stress, allergies (such as hay fever), moist hands and feet, or exposure to nickel (in metal-plated jewelry), cobalt (found in metal-plated objects, and in pigments used in paints and enamels), or chromium salts (used in the manufacturing of cement, mortar, leather, paints, and anticorrosives) may be “triggers” of dyshidrotic eczema. This type of eczema is twice as common in women as it is in men.

Symptoms of dyshidrotic eczema include:

• Small fluid-filled blisters (vesicles) on the fingers, hands, and feet
• Itching
• Redness
• Flaking
• Scaly, cracked skin
• Pain

4. Nummular eczema – nummular dermatitis

Nummular (numb-mu-LUR) eczema, also known as discoid eczema and nummular dermatitis, is a common type of eczema that can occur at any age. It looks very different than the usual eczema and can be much more difficult to treat. People with nummular eczema develop coin-shaped spots on their skin, which may be very itchy. It is thought to be “triggered” by things like insect bites, reactions to skin inflammation, or dry skin in the winter.

Some symptoms of nummular eczema include:

• Round, coin-shaped spots
• Itching
• Dry, scaly skin
• Wet, open sores

5. Seborrheic dermatitis

Considered a chronic form of eczema, seborrheic dermatitis appears on the body where there are a lot of oil-producing (sebaceous) glands like the upper back, nose and scalp.

Seborrheic dermatitis on the scalp is called dandruff.

The exact cause of seborrheic dermatitis is unknown, although genes and hormones play a role. Microorganisms such as yeast, that live on the skin naturally can also contribute to seborrheic dermatitis. Unlike many other forms of eczema, seborrheic dermatitis is not the result of an allergy.

People of any age can develop seborrheic dermatitis including infants (known as “cradle cap”). It is slightly more common in men than women.

People with certain diseases that affect the immune system, such as HIV or AIDS, and the nervous system, such as Parkinson’s disease, are believed to be at an increased risk of developing seborrheic dermatitis.

Seborrheic dermatitis often appears on the scalp, where symptoms may range from dry flakes (dandruff) to yellow, greasy scales with reddened skin. Patients can also develop seborrheic dermatitis on other oily areas of their body, such as the face, upper chest and back.

Common symptoms of seborrheic dermatitis include:

• Redness
• Greasy, swollen skin
• White or yellowish crusty flakes

6. Stasis dermatitis

Stasis dermatitis is also called gravitational dermatitis, venous eczema and venous stasis dermatitis. It happens when there is a problem with blood flow in the veins and pressure develops (usually in the lower legs). This pressure can cause fluid to leak out of the veins and into the skin, resulting in stasis dermatitis.

Symptoms of stasis dermatitis include:

• Swelling around the ankles
• Redness
• Scaling
• Itching
• Pain

And in more severe cases:

• Oozing
• Open areas (cracking or larger ulcers)
• Infection

Nummular eczema (also known as discoid eczema and nummular dermatitis) is a form of eczema that can occur at any age. It looks different than other types of eczema and can be difficult to treat because it seems to affect people differently.

The word “nummular” comes from the Latin word for “coin,” as the spots can look coin-shaped on the skin. The spots may be very itchy or not itchy at all. They can be very dry and scaly or can become wet and open.

The cause of nummular eczema (nummular dermatitis) is unknown, but it does not seem to run in families.

Known triggers for nummular eczema include:

• Damage to the skin such as through an insect bite, scrapes and scratches, chemical “burns”
• A reaction to inflammation (as with atopic dermatitis and/or statis dermatitis) elsewhere on the body
• Dry skin especially in the winter
• Metals like nickel
• Poor blood flow or swelling in the lower legs
• Medications like topical antibiotic creams, isotretinoin and interferon

Because nummular eczema (nummular dermatitis) can look like ringworm, it is important to make sure that it is not a fungal infection, especially if it is not responding to treatment. This can usually be done by your health care provider with a skin scraping or a fungal culture.

Like atopic dermatitis, nummular eczema (nummular dermatitis) can get infected by bacteria — usually staph. Make an appointment with your doctor if you think you have an infection on your skin where the nummular eczema appears.

Nummular eczema appears more frequently in men, usually between the ages of 55-65. Women usually get their first flare of nummular eczema between the ages of 13-25. It can also affect children.What does nummular eczema – nummular dermatitis look like?

Symptoms of nummular eczema (nummular dermatitis) include:

• Coin-shaped lesions on arms, legs, torso and/or hands
• Itching and burning
• Lesions that are oozing liquid or have crusted over
• Red, pinkish or brown, scaly and inflamed skin around the lesions

Nummular dermatitis treatment

Like atopic dermatitis, nummular eczema (nummular dermatitis) benefits from moisturizers to calm and protect the damaged skin barrier.

In many cases, you may receive a prescription for a steroid medication to calm the inflammation as well. For some reason, the milder and moderate-potency steroid creams may not be of much help with nummular eczema (nummular dermatitis). More powerful steroid creams are frequently required. Fortunately, nummular eczema (nummular dermatitis) tends to disappear completely after the right treatment.

In cases where steroids are not appropriate, or when you have used them for a long time, your doctor may prescribe phototherapy, coal-tar creams, or a non-corticosteroid topical medication such as tacrolimus (Protopic) or pimecrolimus (Elidel). These medications are called topical calcineurin inhibitors (TCIs) are approved for use by adults and children two years of age or older.

Topical or oral antibiotics may be used when there is a bacterial infection on the skin. In very severe cases, systemic steroids (taken by mouth or given by injection) may be used for a short time to calm symptoms, though they are not recommended.

Atopic dermatitis may look like nummular eczema, especially on people of African-American or Asian descent.

Will nummular eczema ever go away?

Many people, even those who have a severe nummular eczema, seem to clear up completely and do not appear to have the long-term issues like other forms of eczema.
