Young male patient diagnosed with cutaneous polyarteritis nodosa successfully treated with etanercept

Abstract

Cutaneous polyarteritis nodosa (CPAN) is a form of necrotizing vasculitis of small and medium-sized arteries. It is limited to the skin and has a recurrent and chronic course, possibly associated with fever, arthralgia, myalgia and neuropathy, but without visceral involvement. We report the clinical case of a 7-year-old male patient with CPAN refractory to treatment with high doses of corticoids and cyclophosphamide, who was successfully treated with the TNF-α (tumor necrosis factor-alpha) inhibitor, etanercept, in monotherapy.
