Discoid eczema is characterized as coin-shaped patches that are widely scattered on the limbs. This form of eczema can manifest on individuals who have normal skin and causes skin dryness along with atopic eczema.
The affected areas of discoid eczema have well-pronounced borders that are inflamed. There are small-sized blisters, crusts or scales as well. Take note that this often indicates that they are already infected by bacteria.
In most instances, the pattern of the skin lesions on the limbs is proportioned in appearance. The lesions are intensely itchy, thus thickening of the skin is common. Due to the defined borders, the lesions might be mistaken as fungal infections of the skin or contact eczema. Remember that the difference with ringworm is that it has an inflamed appearance with a central clearing instead of being scaly and swollen over the patch.
Discoid eczema can affect individuals in all age groups but typically linked with middle-aged or older men.
Causes of discoid eczema
The exact cause of discoid eczema is unknown even today, but among younger individuals, it appears to exist with the atopic type. Among adults, this type of eczema is likely linked with stress, local irritation of the skin and excessive consumption of alcohol.
It is important to note that the treatment for discoid eczema is similar with the other forms of the skin condition. Nevertheless, this type of eczema is harder to eliminate than the atopic type.
The treatment usually involves the use of more potent steroids. The latest calcineurin inhibitor creams are considered effective in managing the condition and reduces the need for steroids.
Since there is a high risk for infection with discoid eczema, antibiotic treatment whether orally or topical might be required for severe cases.
