Nummular Dermatitis

Nummular dermatitis is a particular form of eczema (atopic dermatitis) characterized by coin-shaped, raised areas on the skin that are scaly.

  • The cause of nummular dermatitis is not known, but it is associated with triggers such as frequent bathing, irritating and drying soaps, and exposure to irritating fabrics such as wool.
  • Those with nummular dermatitis often have some of the signs and symptoms typically associated with eczema.
  • Nummular dermatitis is itchy (pruritic), but it is less itchy than other common diagnoses with scaly plaques, such as psoriasis.
  • Winter is usually the time of onset and severity.
  • Nummular dermatitis can be chronic, and symptoms can go away and recur indefinitely.

Who's At Risk?

Nummular dermatitis may affect people of all ages.

Signs & Symptoms

Nummular dermatitis is most commonly found on the trunk and/or extremities. Round or coin-shaped, pink to red, scaly, raised areas are seen, often with small cracks or superficial breaks in the skin located within.

Self-Care Guidelines

Maintaining healthy skin is very important for sufferers of nummular dermatitis.

  • Moisturizing skin-care routines are essential.
  • Non-soap cleansers, such as Cetaphil®, or moisturizing soaps, such as Dove®, are recommended.
  • Thick moisturizers such as petroleum jelly, Aquaphor® ointment, Eucerin® cream, CeraVe™ cream, and Cetaphil® cream should be applied to damp skin daily after bathing.
  • Attempt to minimize exposure to heat, humidity, detergents/soaps, abrasive clothing, chemicals, smoke, and stress.
  • Fragrance-free laundry detergent may be beneficial.
  • Keep the home humid with a humidifier or setting out bowls of water, especially in the bedroom.

Treatments

Your physician may:

  • Prescribe medium- to high-potency topical steroids to apply to the affected areas twice daily.
  • Recommend light therapy with ultraviolet B for extensive disease.
  • Prescribe oral antihistamines to help relieve itching.
  • Prescribe oral or topical antibiotics if the area becomes infected.
