title: [Value of the biopsy of accessory salivary glands in amyloidosis].
abstract: OBJECTIVE
  To assess the value of accessory salivary gland biopsy for the diagnosis of amyloidosis, a study was conducted in the nephrology and hemodialysis department at Ibn Rochd University Hospital from February 1996 to January 1998.
  
  
  METHODS
  Renal amyloidosis was confirmed by renal biopsy accompanying accessory salivary gland biopsy.
  
  
  RESULTS
  The patient's mean age was 39 years old (range 15-80), with a 4:1-male/female ratio. An infectious cause (either tuberculosis or superinfection and dilatation of the bronchi) was the most frequent (70% of the cases) etiology. All the patients presented renal symptomatology. Nephrotic syndrome predominated. Amyloid deposits were observed in 100% of renal needle biopsies and in 80% of accessory salivary gland biopsies.
  
  
  CONCLUSIONS
  Renal biopsy led to more positive cases than the other biopsies. It may be accompanied by severe complications. Furthermore, biopsy of the accessory salivary glands is a simple and very reliable technique for the diagnosis of amyloidosis. It is currently the best diagnostic test.
