Nummular eczema, also known as discoid eczema and nummular dermatitis, features scattered circular, often itchy and sometimes oozing patches.

Nummular eczema can occur at any age, and males tend to develop it more often than females.


Its causes aren’t clear, but triggers can include very dry or sensitive skin and trauma to the skin from insect bites, scrapes, or chemical burns.

Nummular eczema may also develop as a reaction to some other types of eczema and their triggers, such as contact dermatitis with the chemical nickel. When it appears on the legs, it can be linked to poor blood flow in the lower body and the stasis dermatitis those circulation problems can cause.


  • coin-shaped lesions on arms, legs, torso, and/or hands
  • itching and burning
  • lesions that are oozing liquid or have crusted over
  • red, pinkish or brown, scaly and inflamed skin around the lesion

How is nummular eczema treated?

Nummular eczema can look like psoriasis, ringworm, fungal infection, and other types of eczema, including atopic dermatitis, stasis dermatitis, and contact dermatitis. It can also occur along with those types of eczema, though it often appears as an isolated condition. Dermatologists can usually spot the condition but may take a skin scraping to confirm a diagnosis.

Once correctly diagnosed, nummular eczema tends to disappear completely with the right treatment. However, unlike some other forms of eczema, nummular eczema may need an aggressive type of treatment to induce a remission.

Like atopic dermatitis, patches of nummular eczema are often infected with Staphylococcus aureus (staph), which needs to be treated along with the skin inflammation to clear the condition.

Nummular eczema can be treated with a mid- or high-potency topical corticosteroid, along with a topical antibiotic. If eczema patches are substantially weepy and oozy, the application of an astringent compress can help dry the area and drive out any staph infection.
