Extrapulmonary sarcoidosis with chronic renal failure

We present a young woman with extrapulmonary sarcoidosis who had been treated for tuberculosis 15 years earlier. The initial diagnosis had been made on the basis of liver biopsy. The patient later developed bilateral visual loss secondary to uveitis. We identified noncaseating granulomatous lesions in the kidney, intra-abdominal lymph node, and previous liver biopsy specimens. Although rare, renal sarcoidosis can manifest itself as hypercalcemic nephropathy, granulomatous interstitial nephritis, renal tubular dysfunction, or glomerulonephritis. Corticosteroids are the treatment of choice.
