Cutaneous granulomatous vasculitis: Its relationship to systemic disease

Abstract

Microscopic and medical review of twenty-six patients with skin biopsy specimens that showed granulomatous vasculitis demonstrated vascular histiocytic granulomas with fibrinoid destruction of blood vessels in the dermis and panniculus. Cultures of the biopsy specimens were nonspecific. The skin lesions varied from erythema to papulonodular and vesicular eruptions; they were usually on the extremities but also involved the trunk. Eight patients had systemic lymphoproliferative diseases: three, lymphoma; two, angioimmunoblastic lymphadenopathy; two, preleukemia; and one, chronic granulocytic leukemia. Five of these eight patients died within 2 years after the onset of skin lesions. The four patients with systemic vasculitis died within 1 year after the onset of skin lesions. Five patients with arthritis, four with gastrointestinal disease, three with systemic sarcoidosis or sarcoidlike disease, and one with tuberculosis had a more favorable prognosis. The histologic pattern of cutaneous nonlymphomatoid granulomatous vasculitis is associated with significant systemic disease, especially lymphoproliferative disorders. Patients with lymphoproliferative disorders or systemic vasculitis have a much poorer prognosis than those with inflammatory or infectious granulomatous disease.
