title: A case of Henoch-Schönlein purpura in disseminated tuberculosis.
abstract: Tuberculosis is still a common disease, even in some parts of developing countries. Although its major impact is pulmonary, the tuberculosis is actually a disseminated disease. An unusual form of renal involvement of tuberculosis is glomerulonephritis, as a part of systemic vasculitis, Henoch-Schoenlein Purpura (HSP). A 41-year-old man, being treated with antituberculous agents for pulmonary tuberculosis, was transferred to our hospital because of newly developed generalized purpura and pretibial edema. Renal manifestations were proteinuria and hematuria. Renal biopsy disclosed interstitial chronic granulomatous inflammation with caseous necrosis and strong nodular mesangial Ig A deposit, along with trace granular Ig G deposition and perivascular C3 deposit. Skin lesions were non-thrombocytopenic palpable purpurae, proved leukocytoclastic vasculitis by skin biopsy. All clinical symptoms and signs were relieved by antituberculous medication. We concluded that disseminated tuberculosis might be a cause of HSP, an immune complex mediated disease.
