[Recurrent polychondritis with renal microaneurysms and segmental necrotizing glomerulonephritis]

The authors report a case of relapsing polychondritis, in a 41 year-old man, with renal complication. Immunofluorescence study of this segmental necrotizing glomerulonephritis showed an important fibrin fixation without immunoglobulins. Selective renal arteriography, preliminary to the biopsy, showed lobular arterial aneurysms. Because of other exceptional cases of literature, relation between periarteritis nodosa and relapsing polychondritis is discussed.
