Disorders associated with cutaneous vasculitis include numerous well-described etiologies. Primary cutaneous vasculitis limits discussion to primary leukocytoclastic vasculitis, essential mixed cryoglobulinemia, urticarial vasculitis, Henoch-Schönlein purpura, and erythema elevatum diutinum. Although the therapeutics for these disorders are based on limited data, we attempt to construct a consensus opinion on the management of primary cutaneous vasculitis. Therapy of primary cutaneous vasculitis is indicated for symptomatic or systemic involvement, because cutaneous small vessel vasculitis is frequently a self-limited, single episodic disease. Conservative, symptomatic treatment includes leg elevation, warming, antihistamines, and nonsteroidal anti-inflammatory drugs. For mild recurrent disease, colchicine, dapsone, and prednisone are first-choice agents. Systemic or severe cutaneous disease requires more potent immunosuppression (eg, prednisone, azathioprine, or mycophenolate mofetil). Plasmapheresis/plasma exchange and intravenous immunoglobulin are viable considerations for refractory disease, but are cumbersome and expensive modalities. There is insufficient evidence to advocate the use of new biological or monoclonal antibody therapies in primary cutaneous vasculitis.
