Discoid eczema

Discoid eczema: Introduction

Discoid eczema is an allergy-related chronic skin condition. Discoid eczema is marked by itching, inflammation, redness, and scaling of coin-shaped patches on the skin. Discoid eczema is an uncommon type of eczema, a form of dermatitis. Discoid eczema is also called nummular dermatitis and gravitational discoid eczema.

Discoid eczema leads to the development of coin-shaped lesions or sores that can come and go and vary in number and size. Uncomplicated discoid eczema is not a serious condition, but it can lead to complications that can be serious in some people. Excessive scratching is often the cause of complications. For more specifics about other key symptoms and complications, refer to symptoms of discoid eczema.

The exact cause of discoid eczema is unknown, but it is linked to allergies. Exposure to certain triggers, such as stress, allergens, temperature chances and skin irritants, can lead to a flare-up of discoid eczema in sensitive people. Having dry skin is also associated with discoid eczema.

The appearance, severity, symptoms, and triggers of discoid eczema vary between individuals. People who are more likely to develop discoid eczema include those with a personal or family history of allergies, atopic dermatitis or asthma.

A diagnosis of discoid eczema can often be made by taking a thorough health history, including symptoms, and performing a physical exam. The condition can generally be diagnosed by its appearance.

For some people, skin patch testing may be performed. In a patch test, small amounts of common allergens are applied methodically to the skin to determine what substances can trigger an allergic response and can possibly lead to a flare-up of discoid eczema symptoms.

A skin biopsy may also be performed as a part of the diagnostic process. A skin biopsy can rule out some similar diseases and conditions. A culture and sensitivity test may also be done if it is suspected that the lesions of discoid eczema are infected. A culture and sensitivity test can determine the type of microorganism that is causing the infection, such as bacteria, and help to determine the most effective medication for treatment.

Because the symptoms of discoid eczema may be similar to other skin conditions, such as psoriasis, poison ivy, or pityriasis rosea, a misdiagnosis is possible. For information on other diseases, disorders and conditions that can mimic discoid eczema, refer to misdiagnosis of discoid eczema.

Discoid eczema is a chronic condition, and there is currently no cure. However, the symptoms of discoid eczema can be controlled with a good treatment plan individualized to a person's medical history, severity of discoid eczema, and other factors.

Treatment begins with the prevention of flare-ups of skin spots, patches and lesions. This includes an integrated plan to reduce exposure to irritants, allergens, and other triggers, and minimize skin dryness. A variety of topical and oral medications may be prescribed to sooth the skin, reduce itching and inflammation, and cure secondary infections.

A combination of treatments that include lifestyle changes with medications and other treatments as appropriate is the most effective way to best control discoid eczema. For more information on specific treatments, refer to treatment of discoid eczema. ...more »
