Submandibular accessory salivary gland causing Warthin's duct obstruction

Background. Submandibular masses are mostly secondary to sialolithiasis. Sa livary 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 inv estigation showed the accessory salivary tissue, which was narrowing the Wa rthin's duct. Conclusions. In cases of a symptomatic submandibular accessory gland, excis ion extirpation of the submandibular gland and accessory salivary tissue sh ould be undertaken. (C) 2000 John Wiley & Sons, Inc.
