Nummular Dermatitis: Description, Causes, and Treatment Protocol

by Curtis Jameson
Nummular Dermatitis


Nummular dermatitis is a  type of persistent dermatitis,   commonly referred to as  nummular eczematous dermatitis or discoid eczema.  It usually manifests  clearly as delineated coin-shaped spots of erythema or redness, scaling, and exudation on certain areas of the body. Although the precise origin of nummular dermatitis is  unknown, researchers believe that  a mix of genetic susceptibility, environmental factors, and skin barrier failure is the  key factor.

The defining feature of nummular dermatitis is the appearance  of oval or round lesions that usually vary in dimension from  a few millimeters to several inches.  Lesions frequently appear on irritated, dry, or damaged skin and can be quite painful  or itchy. Due to constant scratching, affected regions can  develop crusts, blisters, or excoriations,  occasionally resulting in secondary infestations.

Nummular Dermatitis: Description, Causes, and Treatment Protocol is an original (HealthXWire) article.

Possible Causes

Nummular dermatitis has an unclear origin, but it is believed to be influenced by multiple factors. Such factors consist of:

Skin Barrier Dysfunction: Skin that has a compromised skin barrier function is more prone to irritation, allergies, and microbial invasion, which can result in an inflammatory reaction.

Environmental Triggers: Nummular dermatitis can be brought on or made worse by dry air, a lack of humidity, exposure to specific metals like nickel, and cobalt, repeated hot baths or showers, along with other harsh chemicals.

Allergic Reactions: An allergic response can  result in nummular dermatitis if you  come into contact with things like scents, colors, metals, or specific materials.

Genetic Predisposition: If you have a family record or  genetic differences that include a history of nummular dermatitis, this could also be a factor.

Exacerbating and Mitigating Factors

Nummular dermatitis is made worse by various factors:

Bathing or Showering Frequently in Hot Water: Long-term hot water exposure  with daily bathing can deplete your skin’s natural oils and disturb your skin’s protective barrier, causing dryness and the escalation nummular dermatitis.

Cold and Dry Weather Conditions: Dryness and worsening nummular dermatitis signs can be brought on by low humidity and chilly temperatures. Due to greater moisture removal from your skin caused by cold temperatures and decreased humidity, inflammation, and irritation are more likely to occur.

Irritating or Abrasive Clothing: The symptoms of nummular dermatitis can be triggered or made worse by irritation and friction caused by abrasive or rough clothing, like synthetic or wool materials. It is advised that you  wear comfortable, breathable clothing produced from natural fabrics like cotton.

Stress and Anxiety:  Anxiety and stress can make nummular dermatitis worse. Stress canexacerbate flare-ups by weakening your body’s immune system and inducing inflammatory reactions.

 Medications: Angiotensin-converting enzymes or ACE inhibitors and beta-blockers, both of which are used for treating  cardiovascular diseases, have also been linked to an increased risk of nummular dermatitis. If  you think your medicine is making your  condition worse, talk to your doctor about possible replacements.

These are some of nummular dermatitis mitigating factors:

Regular Skin Moisturization: Nummular dermatitis management demands maintaining the skin’s moisture levels.  To keep moisture in your skin after a shower or bath, apply  your moisturizer right away.  To reduce potential irritants, you  should opt for hypoallergenic and fragrance-free moisturizers.

Putting on Soft, Breathable Clothes: It is essential to wear comfortable, breathable clothing with a loose fit, such as cotton. These materials will  minimize your irritation and aid in your  skin’s ability to heal by reducing friction and allowing your  skin to breathe.

Avoiding Harsh Detergents and Soaps: To avoid robbing your  skin of its own natural oils and aggravating it even  more, you should  choose gentle, fragrance-free cleansers rather than abrasive detergents or soaps.

Managing Stress: Using stress-reduction strategies like yoga, deep breathing exercises, meditation, or indulging in enjoyable hobbies and pastimes might help lower your stress levels and possibly relieve your  symptoms of nummular dermatitis.

Finding and Preventing Personal Triggers:  Pay attention to circumstances that exacerbate or cause the onset of your  symptoms. These can differ from person to person  based on certain allergies, irritants, or environmental factors. Recognizing and preventing these triggers can reduce flare-ups and enhance your symptom management.

Standard Treatment Protocol

Topical medicines, moisturizers, and dietary changes are all components of the typical treatment plan for nummular dermatitis. These are the main factors of  therapy protocol:

Topical Calcineurin Inhibitors: Pimecrolimus and tacrolimus are  topical calcineurin inhibitors that are used when corticosteroids are not appropriate or when prolonged administration is required. Without having the negative effects linked to corticosteroids, these drugs modify your  immune system and reduce inflammation. In delicate situations or for extended therapy, they are beneficial.

Topical Corticosteroids: Topical corticosteroids with a potency of mid to high are frequently recommended to treat inflammation and irritation. These medicines aid in symptom relief and healing. However, due to potential side effects like skin thinning, the development of striae, along with rebound flare-ups, prolonged usage of corticosteroids should  be avoided.

Moisturizers: Emollients and moisturizers must be applied often and on a regular basis to keep your  skin hydrated and improve your  skin barrier.  To replenish moisture and prevent dryness, you  should look for solutions that have components like hyaluronic acid, ceramides, glycerin, or urea.

Wet Dressings: Wet dressings should be used in serious situations or when there are flare-ups. This  entails wrapping the impacted regions in moist bandages or wraps that have been dipped into water or a calming solution. Wet dressings aid in skin comfort, inflammation reduction, and wound healing.

In addition to improving your overall skin health, they could  help reduce your discomfort and edema. Your  medical professional should be consulted for guidance on the appropriate dose and suitability.

  • Probiotics

  • Aloe Vera Gel

  • Calendula

Creating a successful treatment strategy for controlling nummular dermatitis requires an individualized approach.
