Information about Nummular Dermatitis

Nummular dermatitis
Classification & external resources
ICD-10L30.
ICD-9692.9
Nummular dermatitis is one of the many forms of dermatitis. Also known as discoid dermatitis, it is characterized by round or oval-shaped itchy lesions. (The name comes from the Latin word "nummus," which means "coin.") The disorder is recurrent and chronic, and may appear at any age, although it is most common in people in their 60's. Nummular dermatitis does not appear to be a genetic condition, is not related to food allergies, and is not contagious.

The coin-shaped patches can affect any part of the body, but the legs and buttocks are the most common areas. Flare-ups are associated with dry skin, so the winter season is a particularly bad time for those with this condition.

One of the keys to treatment and prevention involves keeping the skin moisturized. Lotions, creams, and bath oils may help prevent an outbreak. If the condition flares up, a common treatment involves the application of topical corticosteroids. Oral antihistamines may help lessen itching. More severe cases sometimes respond to ultraviolet light treatment.
