Relapsing polychondritis is a rare systemic disease. Skin involvement occurs in 20 to 50 % of cases. Cutaneous signs are most often related to a leukocytoclastic vasculitis. Association of relapsing polychondritis with neutrophilic dermatosis have also been reported. We report the first case of an erythema annulare centrifugum-like dermatosis associated with relapsing polychondritis, with a two years delay between both conditions. ⋯ Cutaneous signs of relapsing polychondritis are frequent and may occur several months or years before the chondritis. They are polymorphous, but to the best of our knowledge, a clinical aspect of erythema annulare centrifugum has never been described. Our observation recalls the sometimes long delay between the cutaneous and the chondritic signs of relapsing polychondritis and the high frequency of dysmyelopoiesis in relapsing polychondritis with cutaneous involvement.
