Nummular eczema (also called discoid eczema or nummular dermatitis) is a rare skin disease which is in most cases chronic and is characterized by the formation of small, distinct and itchy coin-shaped spots on the skin. These spots may either be dry and crusty or tender and pus-filled. Nummular eczema occurs more often in males than in females and usually follows a skin injury, like a cut or a burn. Despite all the frustration you may feel when experiencing this form of eczema, the condition is not contagious and can be treated with medicines.

Symptoms of Nummular Eczema

The most obvious symptom of nummular eczema is the growth of a single patch or multiple patches of coin-shaped lesions on your skin. They are usually red, brown or pink in color with the surrounding area of skin being scaly or inflamed. Most commonly found in the arms or legs, they tend to be very itchy and may also burn, oozing out liquid followed by the formation of crusts.

Causes of Nummular Eczema

There are no definite causes of nummular eczema but studies have shown that they are more likely to occur in people who have personal or family histories of atopic dermatitis, other allergies or even asthma. Other factors contributing to the growth of nummular eczema include the following:

i. Dry and scaly skin
ii. Temperature changes
iii. Environmental allergens and irritants
iv. Stress
v. Infections

Treatment of Nummular Eczema

Although there is no specific cure for nummular eczema, it can be controlled by avoiding the following:

  1. Harsh soaps and cosmetic products
  2. Wool and nylon fabric
  3. Stressful situations
  4. Excessive bathing and use of hot water
  5. Use of fabric softeners
  6. Exposure to environmental irritants like dust and pollen
