Centrifugal erythema annulare can be cured with standard treatment. The disease requires aggressive treatment of the primary disease if it is due to a medical condition. If the rash is not well controlled and remains enlarged in size, intensive anti-inflammatory therapy or intensive immunomodulatory therapy is required. You should keep your bed linen flat, clean and dry, and keep the scabs off at all times to keep the wounded area dry, while taking rest and avoiding overexertion.
