The main symptom of discoid eczema is skin rashes.
Discoid eczema is a type of dermatitis, or skin disease, characterized by rashes on the affected part of the body. It is not infectious and does not result from an allergy. It can occur at any age and affect any part of the body. Discoid eczema is also known as nummular eczema and nummular dermatitis.
The main symptom of discoid eczema is a rash that develops on the affected part of the body. Although this type of dermatitis can occur anywhere, it is more likely to affect the lower legs. One or more patches can be developed at the same time. They are usually round or oval and of variable size. The lesions can be as small as a few millimeters in diameter or can cover an area of 3 inches (7.5 cm) or more.
When patches of discoid eczema develop on the skin, certain types of over-the-counter medications can help relieve itching and other symptoms.
Most lesions are pale pink or shiny, but they can also appear brown or red. Some lesions are very itchy or the skin around the lesions can become dry, irritable and prone to inflammation. These lesions usually disappear without leaving scars. In some people, however, the lesions can persist for months or even years. Sometimes the injuries can cause permanent scarring or skin discoloration.
Discoid eczema does not occur as a result of an allergy.
This type of dermatitis is not usually caused by the use of cosmetic products, but can worsen with any product that dries the skin. It can often be triggered by a minor burn, insect bite, or other type of minor skin injury. Skin irritation caused by cold, dry weather can also cause this type of dermatitis in susceptible people.
Discoid eczema can disfigure the skin, so one of the most important treatment considerations is protecting the skin from permanent damage. Taking care of the skin after a minor injury, such as an insect bite or a burn, can help prevent the development of this type of dermatitis. This is especially important for susceptible people.
When patches of discoid eczema develop on the skin, certain types of over-the-counter medications can help relieve itching and other symptoms. This includes oral antihistamines and anti-inflammatory pills or creams. The skin can be further protected by the use of moisturizers, bath oils, and other skin care products that help keep the skin hydrated. Soaps that dry out the skin should be avoided, as they can irritate the skin and make itching worse. Lanolin and glycerin based creams are particularly useful.
When these home treatments don’t help, prescription medications, such as topical steroid creams, can help reduce inflammation and skin irritation. If the skin is watery or crusty, oral antibiotics may be needed to ensure an infection does not occur. In very severe and long-lasting cases, ultraviolet light therapy is very effective. This treatment involves exposing the affected skin area to ultraviolet light several times a week. It may take several months to clear dermatitis using this method, but it is an effective and long-lasting treatment.
