Answer

Defining the incidence and the prevalence of erythema annulare centrifugum (EAC) is difficult because the literature mostly consists of case reports and brief reviews. In a review of 24 cases in England, the incidence was reported to be approximately 1 case per 100,000 population per year in a catchment area of 500,000 people.
