title: [Idiopathic local bladder amyloidosis].
abstract: OBJECTIVE
  To report one case of primary bladder amyloidosis.
  
  
  METHODS
  We studied a male patient with asymptomatic hematuria by means of transurethral resection.
  
  
  RESULTS
  Pathologic features were consistent with amyloidosis of the bladder wall. We cannot prove either sites of amyloid deposits or an etiology for this disease.
  
  
  CONCLUSIONS
  Local idiopathic bladder amyloidosis is a very rare disease and the most common presenting symptom is painless hematuria. It may be difficult to differentiate between this disease and a urothelial bladder neoplasia.
