Nummular Eczema is an itchy skin condition that shows up as coin shaped lesions or patches on the skin, usually on the legs and arms, but can spread to the torso. Because of the shape of the lesions, this condition is also referred to as discoid eczema.
Lesions that form will normally appear red, blistered, scaly, and crusted. These lesions not only itch, suffers also experience a burning sensation. Sometimes the smaller round lesions merge together and form a larger lesion. Because of their round appearance, especially as the lesions begin to heal from the center, creating a ‘ring effect’, Nummular eczema is often mistaken for ringworm.
As with most types of eczema, there is no known cause of Nummular eczema, although it is relatively uncommon, and most often occurs in elderly men.
You are more likely to develop a case of Nummular eczema if you suffer from another form of eczema or atopic eczema – the most common form of eczema. Several things such as dry skin, environmental changes, chemical irritants and stress can make the condition worse.
The primary goal of treating Nummular eczema is to identify, and then remove, the irritant that triggers the condition. Thereafter, treatment is similar to other treatments for eczema and may consist of a multi-layered approach.
Over the counter topical corticosteroids to treating the itch and discomfort can be used with some success, however, if your symptoms are more severe and become infected then you may need to consult a physician to prescribe an antibiotic to clear the infection.
