title: Relapsing polychondritis presenting as cutaneous polyarteritis nodosa.
abstract: Relapsing polychondritis is an infrequently diagnosed, though not necessarily uncommon, systemic disorder characterized by recurrent and potentially destructive inflammation of cartilaginous structures, the eye, and the audiovestibular and cardiovascular systems. Although dermal involvement occurs in approximately 25% of patients with relapsing polychondritis, in only few cases has a skin biopsy been obtained revealing lesions such as leukocytoclastic vasculitis, livedo reticularis, erythema nodosum or keratodermia blenorrhagicum. We describe a patient with relapsing polychondritis in whom a cutaneous polyarteritis nodosa preceded cartilage inflammation by 6 months. Cutaneous polyarteritis nodosa is a rare form of vasculitis that appears to be limited primarily to the skin, muscles, and joints. In contrast to the systemic form of the disease it is characterized by the absence of visceral lesions and a relapsing but benign course. The present case and the fact that vasculitis is a concomitant feature in approximately 30% of patients with relapsing polychondritis [21] demonstrates that this condition may not represent a distinct clinical entity.
