Sarcoïdose systémique et glomérulonéphrite extra-membraneuse

Renal involvement in sarcoidosis is rare and more often related to calcium metabolism disorders or granulomatous interstitial nephritis. Glomerulonephritis is exceptional. There may be a long latency period between the development of active sarcoidosis and glomerular involvement and inversely. We report a case membranous glomerulonephritis revealing systemic sarcoidosis.
