Discoid eczema starts as very small, red spots that turn into a rash. Ringworm is a circular patch that grows and becomes lighter in the middle, forming a ring. A number of rings may form across the body. Both rashes can itch, but discoid eczema can cause a burning sensation.

Can eczema be in a ring shape?

Both nummular eczema and ringworm appear as a red rash in a ring or coin shape. Both patches can appear dry and itchy and can grow over time and appear in clusters.

Can ringworm be mistaken for eczema?

Ringworm is sometimes mistaken for forms of eczema and other skin conditions, like psoriasis. Unlike nummular eczema, the affected areas don't vary in color, and the patches don't burn and sometimes don't even itch.
