Understanding Nummular Eczema: What You Need to Know

Nummular eczema is a type of eczema that primarily affects adults, although it can also occur in children. It is characterised by the formation of coin-shaped patches on the skin, hence the name “nummular,” which means “coin” in Latin. These patches can range in size from a few centimetres to several inches in diameter and are typically found on the arms, legs, back, and buttocks.

Eczema is a general term used to describe a group of skin conditions that cause inflammation and irritation. There are several types of eczema, including atopic dermatitis, contact dermatitis, dyshidrotic eczema, and nummular eczema. Each type has its own unique set of symptoms and triggers.

Nummular eczema differs from other types of eczema in its appearance and location on the body. Unlike atopic dermatitis, which often affects the flexural areas such as the elbows and knees, nummular eczema typically appears on the extremities. The patches are usually well-defined and have a distinct border. They may be dry and scaly or oozing and crusted, depending on the stage of the condition.

Recognising the Signs and Symptoms of Nummular Eczema

The most common symptoms of nummular eczema include itching, redness, and the formation of round or oval-shaped patches on the skin. These patches can be dry and scaly or moist and oozing, depending on the stage of the condition. They may also become crusted or develop blisters.

The appearance of nummular eczema can vary from person to person. Some individuals may have only a few small patches, while others may have numerous large patches that cover a significant portion of their body. The patches can be pink, red, or brown in color and may be accompanied by swelling and inflammation.

It is important to differentiate nummular eczema from other skin conditions that may have similar symptoms. Conditions such as ringworm, psoriasis, and allergic reactions can also cause round or oval-shaped patches on the skin. A healthcare professional can perform a physical examination and may order additional tests to confirm the diagnosis.

What causes nummular eczema? Common Triggers and Risk Factors

The exact cause of nummular eczema is unknown, but several factors can trigger or worsen the condition. These triggers can vary from person to person, but common ones include dry skin, irritants such as soaps and detergents, allergens such as pollen or pet dander, stress, and changes in temperature or humidity.

Certain risk factors can increase a person’s likelihood of developing nummular eczema. These include a personal or family history of eczema or other allergic conditions, such as asthma or hay fever. People with dry skin are also more prone to developing nummular eczema because their skin barrier is compromised, making it easier for irritants to penetrate the skin.

To avoid triggers and reduce the risk of flare-ups, individuals with nummular eczema should take steps to protect their skin. This includes using gentle, fragrance-free cleansers and moisturisers, avoiding hot showers or baths, wearing loose-fitting clothing made of natural fibers, and using a humidifier in dry environments.

How to Diagnose Nummular Eczema: Tests and Examinations

Diagnosing nummular eczema typically involves a physical examination and a review of the patient’s medical history. The healthcare professional will examine the affected areas of the skin and may ask questions about the symptoms, triggers, and any previous treatments.

In some cases, a skin biopsy may be performed to confirm the diagnosis. During a skin biopsy, a small sample of skin is taken and examined under a microscope. This can help rule out other conditions that may have similar symptoms.

Patch testing may also be recommended to identify any allergens that may be triggering the nummular eczema. This involves applying small amounts of various substances to the skin and monitoring for any allergic reactions.

Blood tests may be ordered to check for underlying conditions that may be contributing to the nummular eczema, such as thyroid disease or autoimmune disorders.

The Importance of Proper Skin Care for Managing Nummular Eczema

Proper skin care is essential for managing nummular eczema and reducing the frequency and severity of flare-ups. One of the most important aspects of skin care for individuals with nummular eczema is moisturising. Keeping the skin well-hydrated can help prevent dryness and itching, which are common triggers for flare-ups.

When choosing a moisturiser, it is important to look for one that is fragrance-free and hypoallergenic. Creams or ointments are generally more effective than lotions because they provide a thicker barrier to lock in moisture. Applying moisturiser immediately after bathing or showering can help seal in moisture and prevent dryness.

In addition to moisturising, it is important to avoid irritants that can trigger or worsen nummular eczema. This includes harsh soaps, detergents, and other personal care products that contain fragrances or other potential irritants. It may also be helpful to wear loose-fitting clothing made of natural fibres, such as cotton, which is less likely to irritate the skin.

Topical Treatments for Nummular Eczema: Corticosteroids and Calcineurin Inhibitors

Topical treatments are often the first line of defence for managing nummular eczema. Corticosteroids are commonly prescribed to reduce inflammation and relieve itching. These medications work by suppressing the immune system’s response and reducing the production of inflammatory substances in the body.

Corticosteroids come in various strengths and formulations, ranging from mild creams or ointments to stronger preparations that may be used for short periods of time. It is important to follow the healthcare professional’s instructions when using corticosteroids, as prolonged use or misuse can lead to side effects such as thinning of the skin, discoloration, and increased susceptibility to infections.

Calcineurin inhibitors are another type of topical medication that may be prescribed for nummular eczema. These medications work by inhibiting the activity of calcineurin, a protein that plays a role in the immune response. Calcineurin inhibitors are typically used when corticosteroids are not effective or cannot be used due to side effects.

Like corticosteroids, calcineurin inhibitors can have side effects, including burning or stinging at the application site, increased sensitivity to sunlight, and an increased risk of skin infections. It is important to discuss the potential risks and benefits of these medications with a healthcare professional before starting treatment.

Oral Medications for Nummular Eczema: Antihistamines and Immunosuppressants

In some cases, oral medications may be prescribed to manage nummular eczema. Antihistamines are commonly used to relieve itching and reduce inflammation. These medications work by blocking the effects of histamine, a substance released by the body in response to an allergic reaction.

Antihistamines can cause drowsiness, so it is important to take them as directed and avoid activities that require alertness until you know how the medication affects you. Some antihistamines are available over-the-counter, while others require a prescription.

Immunosuppressants may be prescribed for individuals with severe or persistent nummular eczema that does not respond to other treatments. These medications work by suppressing the immune system’s response, which can help reduce inflammation and prevent flare-ups.

Immunosuppressants can have serious side effects and should only be used under the supervision of a healthcare professional. Regular monitoring of blood tests may be necessary to check for any potential complications.

Natural Remedies for Nummular Eczema: Do They Work?

Many people with nummular eczema turn to natural remedies in an effort to manage their condition. While some natural remedies may provide temporary relief, there is limited scientific evidence to support their effectiveness in treating nummular eczema.

Common natural remedies for nummular eczema include applying coconut oil, aloe vera gel, or chamomile tea compresses to the affected areas. These remedies may help soothe the skin and reduce inflammation, but they are not a substitute for medical treatment.

It is important to note that natural remedies can also have side effects or interact with other medications. It is always best to consult with a healthcare professional before trying any new treatment.

Coping with Nummular Eczema: Tips for Managing Flare-Ups and Itching

Managing flare-ups and itching is a key aspect of coping with nummular eczema. There are several strategies that can help individuals find relief and improve their quality of life.

To manage itching, it may be helpful to apply a cold compress or take a cool bath or shower. Avoiding hot water and harsh soaps can also help prevent further irritation. Moisturizing regularly can help keep the skin hydrated and reduce dryness and itching.

To prevent flare-ups, it is important to identify and avoid triggers. This may involve keeping a journal to track potential triggers, such as certain foods, environmental factors, or stressors. It may also be helpful to wear loose-fitting clothing made of natural fibers, avoid excessive sweating, and maintain a consistent skincare routine.

Coping strategies such as stress management techniques, support groups, and counseling can also be beneficial for individuals with nummular eczema. These strategies can help individuals better cope with the emotional and psychological impact of living with a chronic skin condition.

Preventing Nummular Eczema: Lifestyle Changes and Prevention Strategies

While it may not be possible to prevent nummular eczema entirely, there are several lifestyle changes and prevention strategies that can help reduce the risk of developing the condition or experiencing flare-ups.

Maintaining good skincare habits, such as moisturising regularly and avoiding irritants, can help protect the skin and reduce the risk of dryness and inflammation. It is also important to avoid scratching or rubbing the affected areas, as this can worsen symptoms and increase the risk of infection.

For individuals with a personal or family history of eczema or other allergic conditions, taking steps to manage these conditions can help reduce the risk of developing nummular eczema. This may include avoiding known triggers, such as certain foods or environmental allergens, and seeking medical treatment for any underlying conditions.

If you suspect you may have nummular eczema or are experiencing symptoms such as itching, redness, or the formation of round or oval-shaped patches on the skin, it is important to seek medical attention. A healthcare professional can provide an accurate diagnosis and develop a personalised treatment plan to help manage your condition.
