Erythema marginatum is described as the presence of pink rings on the trunk and inner surfaces of the limbs which come and go for as long as several months. It is found primarily on extensor surfaces.
It occurs in less than 5% of patients with rheumatic fever, but is considered a major Jones criterion when it does occur. The four other major criteria include carditis, polyarthritis, Sydenham’s Chorea, and subcutaneous nodules.
Some sources distinguish between the following:
- “Erythema marginatum rheumaticum”
- “Erythema marginatum perstans”
