Cutaneous Polyarteritis Nodosa

Research output: Chapter in Book/Report/Conference proceedingChapter


Cutaneous involvement of medium vessel vasculitis most commonly presents with features of inflammatory subcutaneous nodules, purpura, livedo reticularis, and ulceration. The clinical and histopathologic features of isolated cutaneous polyarteritis nodosa (c-PAN) are indistinguishable from the cutaneous involvement of systemic polyarteritis nodosa; however, these conditions differ in their prognosis and treatment. An approach to distinguish between these clinical entities is herein described. In addition, conditions commonly mimicking cutaneous polyarteritis nodosa are reviewed.
