• Papillary cystadenolymphoma, or Warthin's tumor, is a monomorphic adenoma found in salivary glands. It nearly always occurs in the parotid gland, and is reported to occur in 5% to 14% of all parotid tumors according to most studies. The tumor has a universally accepted male predominance, with an increasing incidence in females having been reported over the last four decades. A review of all primary parotid gland tumors seen at York (Pa) Hospital for the last 10 years was performed. Warthin's tumor was diagnosed histologically in 42 (30%) of 138 primary parotid gland tumors, with no significant sex predominance identified (22 men, 20 women). A significantly higher percentage of all parotid gland tumors, and especially Warthin's tumor, was associated with smoking in both males and females.
