[Progressive systemic sclerosis associated with anti-myeloperoxidase ANCA vasculitis with renal and cutaneous involvement].
Sclerodema renal crisis is the usual form of presentation of renal disease in systemic sclerosis. We report a woman who at age 63 was given a diagnosis of scleroderma with Raynaud's phenomenon and cutaneous, oesophageal and lung involvement but no evidence of renal disease and no treatment with D-penicillamine. Two years later she developed progressive renal failure, nephrotic range proteinuria, haematuria and the presence of serum MPO-ANCA; she was normotensive. Renal biopsy revealed extracapillary and necrotizing glomerulonephritis and skin biopsy showed leucocytoclastic vasculitis. This clinical picture was compatible with necrotizing vasculitis of the microscopic polyarterits type. After treatment with pulse steroids followed by oral steroids and monthly intravenous cyclophosphamide her renal function stabilised and the serum MPO-ANCA disappeared.
