title: Warthin tumor arising from the minor salivary gland.
abstract: Warthin tumor (WT) accounts for 4% to 13% of all salivary gland tumors. This benign tumor, which commonly arises in the parotid gland, is the second most common tumor of the salivary gland. WT is multicentric in 12% to 20% of patients and is bilateral in 5% to 14%. The mean age at diagnosis is 62 years (range, 12-92 years), and it rarely presents (<6%) before age 40 years. Extraparotid WT, arising from the submandibular gland or cervical lymph node for example, is very infrequent, with corresponding incidences of 0.4% to 6.9% and 8%, respectively. Moreover, WT arising from the minor salivary gland is extremely rare, with a reported incidence of merely 0.1% to 1.2%. We report here WT arising from the minor salivary gland in the buccal mucosa in a 66-year-old woman and review cases of WT of the minor salivary gland reported in the English literature.
