Annular erythema

Тодорхойлолт

Annular erythema is the term given to a group of chronic annular and gyrate eruptions in which irregular rings and arcs of elevated erythema form from initial inflammatory papules which slowly enlarge whilst clearing centrally. The lesions are usually located on the buttocks, thighs and upper arms, but any area may be involved. The condition may persist for months to years. In the majority of cases the aetiology remains obscure.
