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.[1] It is found primarily on extensor surfaces.[2]
An association with bradykinin has been proposed in the case of hereditary angioedema.[3]
Presentation
The rings are barely raised and are non-pruritic. The face is generally spared.
Associated conditions
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. In this case, it is often associated with Group A streptococcal infection, otherwise known as Streptococcus pyogenes infection, which can be detected with an ASO titer.
It is an early feature of rheumatic fever not pathognomic of it.[4] It may be associated with mild myocarditis (inflammation of heart muscle). It is also seen in conditions like allergic drug reactions, sepsis and glomerulonephritis.[4]
