title: Peripheral nerves regenerated in familial amyloid polyneuropathy after liver transplantation.
abstract: BACKGROUND
  Liver transplantation holds promise as a treatment for familial amyloid polyneuropathy.
  
  
  OBJECTIVE
  To determine whether peripheral nerves regenerate in patients with familial amyloid polyneuropathy after liver transplantation.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University hospital in Matsumoto, Japan.
  
  
  METHODS
  A 34 year-old-women with familial amyloid polyneuropathy who had liver transplantation and showed marked clinical improvement 3 years after surgery.
  
  
  METHODS
  Histopathologic examination and morphometric analysis of biopsy specimens taken from sural nerves.
  
  
  RESULTS
  Diffuse fiber loss and amyloid deposits were seen in a biopsy specimen of the left sural nerve obtained before liver transplantation (total number of myelinated fibers, 1326/mm2 of the endoneurial area). In the biopsy specimen of the right sural nerve, which was obtained 3 years after transplantation, amyloid deposits remained but the number of myelinated fibers was markedly increased (total number of myelinated fibers, 4740/mm2).
  
  
  CONCLUSIONS
  Peripheral nerves regenerated in a patient with familial amyloid polyneuropathy after liver transplantation.
