Figurate erythemas – update and diagnostic approach

Figurate erythemas (FE) represent an etiopathophysiologically heterogeneous group of diseases defined by their characteristic annular erythematous skin lesions. Diagnosis is made primarily clinical examination together with histological findings; often it a diagnosis exclusion. While some authors discuss FE as reaction pattern rather than distinct entities, others identify four classic FE: erythema annulare centrifugum, gyratum repens, migrans and marginatum. The differential diagnoses are numerous challenging. We therefore present potential diagnostic algorithm for that discriminates the differentials according to temporal evolution clinical/histological phenotype various subtypes. Since may underlying malignancy, diligent clinicians needed when dealing those entities.
