title: [Parotid involvement in Churg-Strauss syndrome].
abstract: BACKGROUND
  Churg-Strauss syndrome is a rare systemic vascularitis. This disease causes eosinophilic tissue infiltration. The most frequent manifestations are cortico-dependent asthma, mono- or polyneuropathy, paranasal sinus polyposis, and digestive and renal dysfunction. Salivary glands are very rarely involved.
  
  
  METHODS
  We describe a case of CSS in a patient presenting with bilateral parotid swelling. The morphological study of salivary glands revealed an unusual thickening of the salivary duct walls.
  
  
  CONCLUSIONS
  Salivary gland involvement in Churg and Strauss syndrome can be difficult to demonstrate histologically; it does not usually present in the clinical foreground of the disease, and can be a source of misdiagnosis. The biopsy should be performed in the symptomatic gland, away from any previous corticoid treatment.
