title: [Rapidly progressing glomerulonephritis with mesangial IgA deposits in sarcoidosis].
abstract: This report concerns a patient with sarcoidosis who developed acute renal failure due to rapidly progressive glomerulonephritis. Renal biopsy revealed severe endo and extracapillary proliferation with diffuse mesangial deposits of IgA, C3 and beta 1-H on immunofluorescence. The possibility of a common immunopathogenic pathway between sarcoidosis and IgA nephritis is briefly discussed.
