Centrifugal annular erythema

Centrifugal annular erythema is a skin redness that occurs with annular lesions. Its cutaneous manifestation consists in the appearance of plaques, which can be itchy and develop in a centrifugal direction (hence the name) starting from a central area, of normal appearance, towards a small raised red area at the edges.

In many cases the origin of this erythema is unknown, although possible causes have been observed from taking drugs (acetylsalicylic acid, vaccine), infectious (streptococcal infection, tuberculosis, influenza, infectious mononucleosis, trypanosomiasis), from dermatological disease chronic (subacute lupus erythematosus, pemphigus) or from cancer in an area far from the lesion (lung, prostate, uterus and leukemia cancer).

Centrifugal annular erythema shows a pattern in successive waves, which lasts for many weeks or months. Its treatment should be aimed at the underlying disease if it can be identified. There is no symptomatic cure for injuries.
