[An unusual slow course of systemic vasculitis with multiorgan involvement]

This paper reports on an unusually slowly progressing course seen in systemic vasculitis of the median and smaller arteries and small veins associated with dermatomyositis, chronically active hepatitis, glomerulonephritis of the immune complex and restrictive cardiomyopathy in a 35-year-old patient. The authors discuss the difficulties in establishing the diagnosis and in finding the exact classification of this disease.
