title: [Painful thoracic neuropathy disclosing Sjögren's syndrome: first report].
abstract: BACKGROUND
  Thoracic neuropathy is rare, and is usually associated with diabetes mellitus. We report a first case of isolated multi-metameric thoracic neuropathy revealing Sjögren's disease.
  
  
  METHODS
  A 64-year old man consulted for symptoms suggesting a progressive and extensive (from T7 to T10) bilateral thoracic neuropathy. Diabetes mellitus and other causes of neuropathy were excluded. Spinal MRI, electromyography and CSF analysis were normal. Though the patient had no sicca syndrome symptoms, the diagnosis of Sjögren's syndrome was made on hypergammaglobulinemia, elevated ACAN (1/5000) with anti-SSA specificity and a grade III minor salivary gland biopsy. He improved spectacularly on corticosteroids (prednisone, 1 mg/kg/d). Sicca syndrome became clinically evident in April 2006.
  
  
  CONCLUSIONS
  Pure sensitive thoracic neuropathy can reveal Sjögren's syndrome.
