A Case of Cutaneous Polyarteritis Nodosa

Abstract

Cutaneous polyarteritis nodosa(CPAN) is a benign form of rare vasculitis of small and medium-size arteries with a recurrent but benign course without systemic involvement. We experienced a 61-year-old male who had two months history of multiple deep-purpurish livedo reticularis on both lower legs. Noncutaneous manifestations including malaise, fever, myalgia, and arthritis were absent. A skin biopsy specimen from the livedo reticularis on the leg showed perivascular and trans-mural neutrophilic and lymphocytic infiltration of medium-sized arteries in the dermal-subcutaneous junction and fibrinoid necrosis of the vessel walls. The patient was treated with colchicine for 2months and showed markded improvement.
