Erythema annulare centrifugum (EAC) is a rare skin disease that is thought to be caused by interactions between inflammatory cells, mediators, and foreign antigen substances. It typically starts as erythematous macules or urticarial papules that enlarge peripherally to form an arcuate or polycyclic plaque. Symptomatic relief is the main therapy for this disease because no effective treatment is yet available. Read More

Figurate erythemas (FE) represent an etiopathophysiologically heterogeneous group of diseases defined by their characteristic annular erythematous skin lesions. Diagnosis is made primarily by clinical examination together with histological findings; often it is a diagnosis made by exclusion. While some authors discuss FE as clinical reaction pattern rather than distinct clinical entities, others identify four classic FE: erythema annulare centrifugum, erythema gyratum repens, erythema migrans and erythema marginatum.
