Good job. Erythema Marginatum is a major manifestation of rheumatic fever. This manifestation is a skin rash with a central clear area. The periperhy of the rash is red and follows a serpentine course on the skin. The rash will disappear and appear on different portions of the body in a couple of hours time. Go back and find the other major manifestations. If you have found them all then continue to the next question.
