Also known as nummular dermatitis, Discoid eczema is usually seen in adults with dry skin although it can affect teenagers and young children, but this is rare.
It is very distinct with ‘coin shaped’ discs of eczema the size of a fifty pence piece that start off slightly bumpy, usually on the lower legs, trunk or forearms. Within a few days the patches begin to ooze, and can become very itchy, crusted and infected.
Later on, the surface becomes scaly and the centre of the discs clear, leaving the skin dry and flaky. Like most types of eczema the exact cause is not clear, although dry skin is perhaps the most common feature seen in people with this condition. Other factors include the use of soaps and detergents, and previous experience of atopic eczema.
