What is nummular eczema?

It is a type of eczema which is very itchy and appears as patches or spots on the skin. This type of eczema is also referred to as nummular eczematous dermatitis and discoid eczema. Nummular dermatitis affects both young and adults of all races. But research shows that it is more common in males aging 55 to 65 years old than females, though the condition is also observed in females aged 15 to 25. The lesions are commonly seen on the extremities like the hands, arms and legs, including the torso.

Symptoms of Nummular Eczema

People suffering from nummular dermatitis have disc-shaped patches or spots on their skin. At first, the patches appear red and irritated. After several days, coin-shaped rashes with blisters will emerge on the irritated area.

Nummular dermatitis or eczema often develops on the areas where skin problems once occurred such as burns, insect bites and skin injuries. Unlike other skin problems, this type of eczema is not contagious. However, untreated nummular dermatitis may turn into scaly, dry patches that look like fungus or ringworm, and sometimes, psoriasis. If an individual is affected by this type of eczema, he or she should expect that it will recur because it is a chronic skin disorder.
