What is nummular eczema?

Nummular eczema is a chronic eczema characterised by coin-shaped, sharply demarcated lesions. As it overlaps with other forms of eczema (atopic dermatitis, asteatotic eczema, allergic contact dermatitis, stasis dermatitis), it has been questioned if it is an independent clinical entity. Nummular eczema is more common in males. The traditional view of this eczema

subtype as being caused by microbial agents has not been confirmed.

Nummular eczema is defined by its clinical appearance as coin-shaped patches on the skin. The cause of nummular eczema is unknown, but several possibilities exist for its occurrence. Bacterial infection, for example, might be one cause of this disease. Bug bites, burns, exposure to chemicals, and other skin irritants may stimulate this condition. A low-humidity environment may play a role. Stress may also contribute to the onset of nummular eczema. This disease more commonly affects men than women. The disease typically occurs in the middle years and rarely occurs in children. Nummular eczema has not been associated with any serious underlying disorders, and people who have this condition are generally healthy individuals. The coin-shaped patches typical of nummular eczema often contain tiny bumps and blisters. These patches are reddish in color and may ooze and become crusty. These may grow together to form larger patches. The legs are most commonly affected, but the disease may also involve the trunk and arms, especially the backs of the hands.

The cause is unknown. Only occasionally does this turn out to be a medication allergy, although this is often considered in the evaluation. 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 often have skin that is dry and easily irritated by soap, detergents, and rough clothing. Clothes washed or dried with liquid or sheet fabric softeners such as Kling, may also irritate the skin. Hot and cold weather often aggravates eczema. Certain allergies may worsen eczema, but they don't cause it. This is not the same condition as atopic eczema, a much more common skin problem that can be allergic.

The treatment of this form of the disease is similar to treatment of atopic eczema. First, the patient is advised to avoid the offending agent or trigger. Creams, ointments, lotions, bath oils, and emollients should be used to help hydrate dry, flaky areas. Low-dose topical corticosteroids are used to control the inflammation associated with the rash and promote healing. In some cases, oral antihistamines may be used to control persistent itching and anxiety associated with the rash. Antibiotics may be used if the area becomes infected and weepy. Oral corticosteroids, which can have extensive side effects, are typically recommended only for severe cases of eczema.
