Eczema: Nummular Dermatitis



What Is Nummular Dermatitis?


Nummular dermatitis is a type of eczema that is a result of skin injury. The name nummular means coin shaped and this is a hallmark of this skin condition, nummular lesions. Skin injury such as insect bites, burn, abrasion or aberration heals and after a while lesions may appear that may last for several weeks to months.


Nummular dermatitis is also called discoid eczema, nummular eczema and also nummular eczematous dermatitis.



Signs And Symptoms


Aside from the trademark coin-shaped lesions these are the characteristics of nummular dermatitis:


•   The coin-shaped lesions look like reddish spots that can grow and form together. These lesions can range from less than an inch to more than 4 inches in diameter.


•   These lesions can burst and weep fluid if scratched. When these heal, they become crusty and scaly in the long run.


•   Lesions may also be colored red or brown and sometimes appear as well defined lesions.


•   These coin- shaped lesions often develop in the areas of the torso and in the extremities.


•   Sometime a lesion may look like a ring worm infection. These ring-like patches may burn and itch. The itch may be so severe that it can disrupt sleep.


•   After the skin has healed, hyper pigmentation or hypo pigmentation of the skin may occur and the lesion may never fade from the skin surface even if is completely healed.



Who Gets?


Men are more prone in developing nummular dermatitis and skin experts have found that the age of 55 to 65 are the periods where the person is more likely to develop this skin condition. In the United States alone, 2 out of 1000 people develop nummular dermatitis



Causes


The root cause of nummular dermatitis is unknown but experts believe that people who are highly sensitive to substances and chemicals can develop this skin condition. Exposure to mercury is one of the triggers of nummular dermatitis and mercury is commonly found in dental fillings and other materials in a dental laboratory.


Nummular dermatitis is also common in people who handle materials made of rubber, nickel and formaldehyde. People who are hypersensitive can develop this type of eczema in no time at all.



Treatments


Treatment of nummular dermatitis in the lower extremities may take longer than usual and these are often the techniques used by dermatologists:


•   Increasing moisture on skin can help decrease skin inflammation and severe itching. A lukewarm bath or soak can also help increase skin moisture and after a bath, apply moisturizing lotions or creams to lock skin moisture in.


•   A topical steroid can be prescribed by your dermatologist. He can advise the ideal dosage and strength according to the severity of your nummular dermatitis.


•   Reducing itching can be done by taking antihistamines and applying cool compresses.


•   Topical and oral antibiotics may also be prescribed by your dermatologist to control skin inflammation.


•   Severe cases of nummular dermatitis are treated with light therapy, corticosteroids, dressings and immune system suppressants to control inflammation.



Prevention


Nummular dermatitis can be prevented by a number of methods:


•   Keeping to your skin regimen as advised by your dermatologist can prevent future nummular dermatitis attacks.


•   Avoid activities that can stress you out and make you perspire.


•   Wear loose cotton clothes to absorb perspiration and also to avoid skin irritation.


•   Using a humidifier at home or a pan of water near a fireplace or furnace can significantly increase room moisture. This can ultimately help improve skin moisture as well.
