Erythema annulare centrifugum – http://id.who.int/icd/entity/875793399

Erythema annulare centrifugum is the prototypic "annular erythema". Although it has several characteristic clinical features, it is a diagnosis of exclusion and must be distinguished from the many other specific causes of annular erythema including lupus tumidus, Lyme disease and leprosy. It is characterised by the development of small numbers of pink infiltrated papules which very gradually enlarge whilst fading centrally to form ring-shaped elevated plaques. It most commonly affects the thighs, buttocks or upper arms.
