title: Secondary bladder amyloidosis: a new case report.
abstract: To report a new case of secondary bladder amyloidosis, beinginvolvement of the urinary bladder by amyloidosis infrequent on the basis of very few  references in the literature (we estimate the number of cases of secondary vesical amyloidosis reported to be around 30).
  
  
  
  The case presented here corresponds to secondary bladder amyloidosis in a patient suffering from Still's disease, who began with hematuria  and ended dying.
  
  
  
  Secondary bladder amyloidosis constitutes a very infrequent pathology, and we can distinguish between primary forms of bladder amyloidosis and  systemic forms of amyloidosis that affect the urinary bladder (secondary bladder amyloidosis). It is associated in the majority of patients with rheumatoid  arthritis that has evolved over a long period. Clinical diagnosis is difficult, and it is necessary to carry out differential diagnosis with bladder tumours.  The pathological and immunohistochemical studies confirm the diagnosis.
