What Causes Nummular Eczema?

Eczema is characterized by the immune system's overreaction to substances or stimuli that result in an inflammatory skin reaction.

Eczema is also known as atopic dermatitis because it involves atopy , meaning a genetic tendency to develop allergic diseases such as allergic rhinitis (hay fever), asthma, and eczema.

With that said, scientists have only begun to identify the gene mutations associated with the disease. What they do know is that certain triggers—such as allergies, irritants, environmental changes, and even emotions—can instigate or aggravate symptoms.

The triggers most commonly associated with nummular eczema include:

Nummular eczema is more common in males than females. Males tend to develop symptoms between the ages of 55 and 65, while females generally develop them between the ages of 15 and 25.

Children rarely get nummular eczema and, when they do, it tends to be very severe.

Related Conditions

People with nummular eczema, are more likely to have or develop other related conditions, particularly allergic diseases. Research is ongoing, but some evidence suggests that genetic factors and immune dysfunction may play a role in the connection between these conditions and eczema.

When you live with nummular eczema, the relentless itching and discomfort can disrupt your sleep and daily activities. The discomfort can take a toll on your overall well-being. The good news is that proactive skincare practices can reduce the frequency of flare-ups.

Knowing and avoiding your triggers is one of the best ways to reduce flare-ups, but it may take some time before you can identify them. For some people, this may involve wearing cotton clothing and avoiding extreme weather temperatures. For others, avoiding perfumes and personal care products with fragrance and other added chemicals may help.

When flare-ups occur, ask your healthcare provider to work with you to find effective treatments for symptom relief and clearing your skin. Doing so can help you improve symptoms and better your quality of life.

Overview - Discoid eczema

Without treatment, discoid eczema can last for weeks, months or even years. It may also keep coming back – often in the same area that was affected previously.

Discoid eczema causes distinctive circular or oval patches of eczema. It can affect any part of the body, although it does not usually affect the face or scalp.

The first sign of discoid eczema is usually a group of small spots or bumps on the skin. These then quickly join up to form larger patches that can range from a few millimetres to several centimetres in size.

On lighter skin these patches will be pink or red. On darker skin these patches can be a dark brown or they can be paler than the skin around them.

Initially, these patches are often swollen, blistered (covered with small fluid-filled pockets) and ooze fluid. They also tend to be very itchy, particularly at night.

Over time, the patches may become dry, crusty, cracked and flaky. The centre of the patch also sometimes clears, leaving a ring of discoloured skin that can be mistaken for ringworm.

You may just have 1 patch of discoid eczema, but most people get several patches. The skin between the patches is often dry.

Patches of discoid eczema can sometimes become infected. Signs of an infection can include:

• the patches oozing a lot of fluid
• a yellow crust developing over the patches
• the skin around the patches becoming hot, swollen and tender or painful
• feeling sick
• feeling hot or shivery
• feeling unwell
