title: [Dapsone-induced sensory peripheral neuropathy].
abstract: BACKGROUND
  Peripheral neuropathy is a rare complication of dapsone therapy.
  
  
  METHODS
  A 74 year-old woman was treated with dapsone, 50 mg per day, for a linear IgA dermatosis. One month later, the disease was controlled but the patient complained of a sensory peripheral neuropathy, which was documented on electromyographic studies. Dapsone was stopped and symptoms resolved within 24 hours. Three months after the beginning of linear IgA dermatosis, a colic adenocarcinoma was revealed by an acute occlusive syndrome. After surgical resection of the tumor, remission of linear IgA dermatosis was obtained with salazopyrine.
  
  
  CONCLUSIONS
  This is a rare side effect of dapsone therapy. Twenty-one cases have been previously reported. In most cases, there was a pure motor or mixed neuropathy. Dapsone therapy was then stopped or decreased. Recovery usually occurs within one year after dapsone therapy is discontinued.
