Nummular Dermatitis

What is Nummular Dermatitis?

Nummular Dermatitis (also known as nummular eczema or discoid eczema) is a skin condition characterized by the presence of coin-shaped spots that develop on areas of the body. The term “nummular” comes from the Latin word “coin” hence the name associated with this type of eczema. The spots formed could be very itchy or not itchy at all and can last up to several months. The direct cause of nummular eczema is unknown. There hasn’t been any research concluding a direct link as to why a person gets this condition. This type of eczema can form at any age. The condition is more likely to occur in men than in women. Usually, men have their first episode of nummular dermatitis between the ages of 55 to 65. For women, they usually obtain nummular eczema during adolescence or early adulthood. Often times, it could be hard to treat an individual because it affects each person differently.

What Causes Nummular Dermatitis?

As mentioned before, the cause of nummular dermatitis is unknown. However, individuals that have a history or family history of allergiesasthma, or atopic dermatitis  often have a higher likelihood of obtaining nummular eczema. Some factors may contribute to nummular eczema, these include:

  • Stress
  • Dry Skin
  • Surgery
  • Irritants (soaps, metals, etc.)
  • Temperature changes

Nummular Dermatitis Symptoms

The most common symptom of nummular dermatitis is a patch of round-to-oval shaped lesions (erythematous plaques) on the body. These patches can form anywhere but are most common on the arms or legs. Additionally, the patches can spread up the torso or down to the hands as the condition gets aggravated. These patches of lesions can itch or burn and be very uncomfortable. The color of these lesions can portray themselves to be brown, pink, or red. Skin surrounding the areas may be red, inflamed or scaly. Sometimes the sores may ooze or crust over. If the sores are left untreated, a secondary infection may arise. If the sore starts to develop a yellowish crust, we recommend that the individual call their doctor to get the proper medication to treat the infection.
