1. An Itchy Situation
Nummular eczema or dermatitis (medical name: nummular eczematous dermatitis) is a chronic itchy skin rash that starts as papules (tiny red dots) and vesicles (blister-like lesions) that grow together to form coin-shaped lesions. In many cases, these lesions ooze or weep edematous fluid (fluid in the tissue) that crusts over as it dries, forming scales. The name is derived from Latin, nummular meaning "coin." The most common area to be affected is the legs, followed by the hands, arms and torso. The condition rarely affects children, and is seen most in males between 55 and 65 years of age.
2. Where It All May Stem From
The cause of nummular eczema is not known, but it's thought that several factors likely play a role in the development of the condition. Dry skin is certainly a factor, which is why nummular eczema is seen more in the winter when skin tends to be drier. Bacterial skin infections and an allergy to an acne medication called isotretinoin might also play some part in developing nummular eczema. It is believed that some allergies might affect, but not cause, this condition.
3. Rubbing Nummular Eczema the Wrong Way
Once you have this skin condition, there are some things that can irritate or exacerbate the symptoms. Wearing rough clothing such as wool is not advised. Taking too many showers or baths can dry out the skin as well, and limit the use of soap in the areas where the rash is present. Blot dry, don't rub with a towel after bathing. Using fabric softeners when washing clothes might cause the skin to be irritated. Avoid drastic temperature changes. Some topical ointments or lotions might also be irritants to nummular eczema.
4. Fight Back With Powerful Meds
In many cases, nummular eczema needs to be treated with strong prescription medication. Cortisone or corticosteroid ointments applied to the affected areas is a common and effective method of treatment. Coal tar added to an ointment might be used for persistent nummular eczema. As skin infection is possible, oral antibiotics may also be prescribed. In extreme cases, oral or injection corticosteroids are used.
5. Do-it-yourself Skin Care
As with any chronic condition, those who suffer from nummular eczema need to adopt certain habits and practices to keep the skin moist and to soothe symptoms. The most important thing is to keep the skin lubricated by applying body oil or Vaseline after bathing. Always bathe in lukewarm water, not too hot so as not to dry out the skin. Use moisturizing soaps and not harsh soaps when bathing.
