Abstract
Scleroderma renal crisis is characterized by intimal thickening of the afferent glomerular arterioles resulting in hypertension and fibrinoid necrosis of the capillary tuff. We report a 67-year-old man with long-standing systemic sclerosis who developed normotensive progressive renal failure, proteinuria, and a nephritic urinary sediment with serum myeloperoxidase-antineutrophil cytoplasmatic antibodies (MPO-ANCA). Renal biopsy showed pauci-immune crescentic glomerulonephritis but none of the typical vascular changes of scleroderma renal crisis. Because comparable cases have recently been reported from Japan, normotensive MPO-ANCA-positive crescentic glomerulonephritis may form an entity of progressive renal failure in scleroderma.
