title: Sulfadiazine-induced sialadenitis.
abstract: OBJECTIVE
  To present a case of sialadenitis induced by sulfadiazine.
  
  
  METHODS
  A 50-year-old man with bronchitis developed swelling of the parotid glands and floor of the mouth as well as plugging in his ears 2 hours after ingestion of Bronco-aseptilex (sulfadiazine, cyclamate, and guaiacol). Skin-prick tests performed with serial dilutions of sulfadiazine and Bronco-aseptilex were all negative. We then performed oral challenge tests with Bronco-aseptilex, sulfadiazine, and other compounds of the commercial syrup. Enlargement of the salivary glands was observed after oral challenge tests with Bronco-aseptilex and sulfadiazine.
  
  
  CONCLUSIONS
  We describe a patient who developed drug-induced sialadenitis. The oral challenge test confirmed that sulfadiazine was the etiologic agent.
