Nummular Dermatitis

What is Nummular Dermatitis?

Nummular dermatitis is a type of inflamed skin condition, also referred to as nummular eczema or discoid eczema. It typically appears as very itchy, red and scaly patches on the skin. Nummular dermatitis is most common on the arms, legs, hands and occasionally the face. It's often seen in adults, but children can also develop it.

The exact cause of nummular dermatitis is unknown, but it may be triggered by environmental factors, such as dry weather, exposure to irritants, emotional stress, or aromatic oils.


Nummular dermatitis can have a variety of symptoms, including:

  • Itchy, red, scaly patches on the skin
  • Rashes which form circular or coin-shaped patches
  • Infections in the affected area
  • Increase in itchiness during the night
  • Bleeding cracks in the skin


The goal of treatment for nummular dermatitis is to lessen inflammation and relieve itching. A healthcare professional may prescribe topical corticosteroids, antifungal cream, antibiotics, or immunomodulators. To prevent flare-ups in the future, it is important to use gentle cleansers and moisturizer frequently. It is also important to protect the skin from environmental irritants, such as fragrances, detergents, and rough clothing.
