symptoms

Discoid Eczema, also called Nummular Dermatitis, appears as small circular patches of red skin on the trunk, legs, arms or buttocks.

The affected area may become blistered and scaly and the skin can become itchy and weep fluid.

who does it affect?

Discoid eczema appears most commonly in middle aged to elderly people and is more likely to affect those with a family history of allergies or atopic eczema. It may also be precipitated by a minor skin injury such as an insect bite or burn.

It is most prevalent over the winter months when skin can become dry, but humid summer conditions can also aggravate the condition.

Contact with harsh detergents makes it more likely to develop this type of eczema and stress is believed to aggravate it.

medical treatment

Topical corticosteroids can reduce the itch and inflammation but long term use can lead to thinning of the skin.

Antihistamines may relieve the itch but won't cure the condition.

Oral steroid based drugs are also prescribed; side effects can include a change in skin colour, upset stomach and interrupted sleep patterns. Long term use can result in weakening of the bones, or stunted growth in children.

For more severe cases, steroid injections can be administered.

Antibiotics are also used to treat this condition where the skin becomes infected, but it may reappear when antibiotics are discontinued.

When cases reappear and are particularly resistant to conventional treatments, ultraviolet radiation may be helpful, but may take several months to control the eczema.

natural alternatives

Use emollients to keep the skin moist, but avoid artificial fragrances and petrochemicals such as mineral oil. Oatmeal baths may soothe itchy skin.

Avoid using creams containing lanolin, and avoid wearing woollen clothing in direct contact with the affected areas.

Use mild soaps, free from artificial fragrances, on the skin. Avoid laundry detergents containing artificial fragrances.

Avoid activities that produce excessive perspiration and elevated skin temperature.

Exposure to mild sunlight may be beneficial.
