Nummular eczema is a skin condition that usually affects older men (although anyone can develop this rash). The rash appears as very itchy, circular areas of red, scaling skin. These may crust and ooze if the condition is severe. Like many forms of eczema, this condition is chronic and tends to flare up and resolve. It is usually worse in the winter when the air is dry. The rash is not contagious. However, areas of affected skin are prone to bacterial infection with Staph. Try not to scratch the rash since this can break the skin and make it more vulnerable to infection.

Potential Treatments

Nummular eczema is often difficult to treat effectively. Avoid using soaps, lotions, or laundry detergents/fabric softeners that contain fragrances. Wear cotton clothing whenever possible (don’t wear wool). Keep skin well moisturized with one of the following creams:

  • Aveeno
  • Cetaphil
  • Cerave
  • Eucerin
  • Aquaphor

A persistent leg rash may require treatment with topical or injected steroids. Other potential therapies include coal tar and light therapy.
