According to Patient.co.uk, discoid eczema can resemble ringworm, sometimes leading people to mistake the eczema for ringworm. The similarity in appearance occurs when the eczema skin patches clear in the middle, leaving a ring of eczema visible that looks like ringworm.
According to the UK National Health Service, discoid eczema is not contagious and is not caused by a fungus. In contrast, ringworm is a fungal skin infection that can be passed on to others. Applying correct treatment for discoid eczema is recommended; however, as symptoms such as itching and burning can persist for up to several months when left untreated. This eczema usually occurs in multiple patches on the skin but may appear only in one spot. A person should see his or her doctor to determine if treatment is needed.
