[Glomerulonephritis in sarcoidosis].

A case of lung sarcoidosis and proliferative glomerulonephritis is reported. The medical literature includes several descriptions of coincidence of sarcoidosis and glomerulonephritis, but only three times is complete documentation by standard microscopy, immunofluorescence and electronic microscopy available. In view of the augmented humoral immunity in sarcoidosis, the authors believe that the association of sarcoidosis and glomerulonephritis is more than a fortuitous coincidence.
