Facts on Nummular Eczema

Nummular eczema is a name given to a stubborn, sometimes itchy rash that forms coin-shaped patches on the skin. The lesions as they get older may clear in the center resembling ring worm or fungus. The condition tends to be chronic, with periods of quiescence and exacerbation.The cause is unknown although it is more common in the winter.

Nummular eczema is frequently associated with dry skin. Wool, soaps and frequent bathing (more than once a day) often worsen the condition. People with eczema have skin that is dry and easily irritated by soap, detergents, and rough wool clothing. Clothes washed or dried with liquid or sheet fabric softeners such as Cling, may also irritate the skin. Hot and cold weather often aggravates eczema. Certain allergies may worsen eczema, but they don't cause it.
