title: [Renal sarcoidosis: a series of five patients].
abstract: BACKGROUND
  Renal involvement is uncommon in sarcoidosis, occurring in less than 5% of the patients. Diagnostic delay should be minimal to improve the outcome.
  
  
  METHODS
  From 1996 to 2009, 78 patients were seen for sarcoidosis in the Department of Internal Medicine of Rouen University hospital.
  
  
  RESULTS
  Five patients (6.4%) had renal involvement. Diagnosis of renal involvement and sarcoidosis were concomitant in two patients while in the three remaining patients, renal manifestations occurred during the course of sarcoidosis. The five patients with renal manifestations exhibited: isolated sarcoid granulomatous interstitial nephritis (n=2), sarcoid granulomatous interstitial nephritis and nephrocalcinosis (n=2), renal failure due to hypercalcemia (n=1).
  
  
  CONCLUSIONS
  This series underlines that renal function tests should be performed systematically both during initial evaluation and the follow-up of patients with sarcoidosis.
