Nummular dermatitis

Nummular Dermatitis is a form of eczema that is characterized by coin-shaped spots on the skin. These spots can be itchy and uncomfortable, and they may be filled with fluid. The condition is also known as discoid eczema.

Causes

The exact cause of nummular dermatitis is unknown, but it may be related to a variety of factors. These can include dry skin, particularly in the winter months, and a history of allergies, asthma, or atopic dermatitis. Some people may also develop nummular dermatitis after an injury to the skin, such as a burn or an insect bite.

Symptoms

The primary symptom of nummular dermatitis is the appearance of coin-shaped spots on the skin. These spots can be red, pink, or brown, and they may be filled with fluid. They can also be itchy and uncomfortable. The spots typically appear on the arms and legs, but they can also appear on the torso and hands.

Treatment

Treatment for nummular dermatitis typically involves the use of topical corticosteroids to reduce inflammation and itching. In some cases, a doctor may also prescribe an antibiotic to treat any secondary infections that may have developed. Moisturizing the skin regularly can also help to reduce symptoms.

Prevention

While it may not be possible to completely prevent nummular dermatitis, there are steps that can be taken to reduce the risk. These include avoiding harsh soaps and detergents, moisturizing the skin regularly, and avoiding scratching the skin.
