title: A repeated carpal tunnel syndrome due to tophaceous gout in flexor tendon: A case report.
abstract: BACKGROUND
  Gouty tophi is a rare cause of CTS. We first report a unique case of repeated CTS with gouty tophi in flexor tendon. In the previous literature, the symptoms cases of CTS were gradually increased.

  We report a 44-year-old male porter presented with mass on his left distal forearm combined a repeated carpal tunnel syndrome for 5 years. He felt numbness in fingers and his left palmar. The CTS symptoms had been eased through rest and dugs medication. It recurred twice.
  
  
  METHODS
  Monosodium urate crystal deposits were found in surgery. Histologic findings confirmed the diagnosis of gout.
  
  
  METHODS
  We removed partial of gouty tophus and retained the integrity of the tendon.
  
  
  RESULTS
