Cutaneous polyarteritis nodosa sine nodosa.

Background And Objective: Cutaneous polyarteritis nodosa, a form of vasculitis affecting the small to medium sized arteries, most commonly presents as tender subcutaneous nodules over the lower legs and feet. Other features include livedo reticularis, skin ulcers and tender indurated plaques.

Conclusion: We report a 51-year old woman with a primarily livedo reticularis presentation of cutaneous polyarteritis nodosa without a nodular component.
