title: Submandibular accessory salivary gland causing Warthin's duct obstruction.
abstract: BACKGROUND
  Submandibular masses are mostly secondary to sialolithiasis. Salivary gland tumors should be considered in the differential diagnosis. In this case report, an unusual cause of Warthin's duct obstruction caused by an accessory salivary gland tissue is presented.
  
  
  METHODS
  Sialography revealed the submandibular accessory salivary gland.
  
  
  RESULTS
  Submandibular gland excision was performed and histopathologic investigation showed the accessory salivary tissue, which was narrowing the Warthin's duct.
  
  
  CONCLUSIONS
  In cases of a symptomatic submandibular accessory gland, excision extirpation of the submandibular gland and accessory salivary tissue should be undertaken.
