Answer:
Erythema marginatum is a skin condition that presents as a circular or ring-shaped rash. The rash may be pink or slightly red in color and typically has a clear center with a distinct, raised edge or margin. The outside of the ring may be slightly scaly. The rash is usually not itchy and tends to occur on the trunk or limbs. It can come and go, sometimes lasting for several months. The size can vary from small spots to large patches that cover a significant area on the body.
