How should nodular vasculitis be treated?

Treatment should be directed toward any underlying infection, especially tuberculosis. Studies have demonstrated the responsiveness of mycobacteria-associated lesions to multidrug antituberculous therapy. Symptomatic care includes bed rest, bandages, antiinflammatory agents, and avoidance of potential aggravating factors such as smoking. In more severe non-tuberculous cases, potassium iodide, dapsone, colchicine, antimalarials, tetracyclines, and prednisone can be used.
