PAPILLARY cystadenoma lymphomatosum (PCL) usually comprises about 5% to 10% of neoplasms of the parotid gland.1-7 In our particular hospital (Minneapolis Veterans Administration), the impression was that the occurrence of PCL far exceeded the published frequencies. To evaluate this impression, the records and pathological material of those cases diagnosed as PCL over a ten-year period were examined. The actual incidence was surprising. The reasons for this high incidence emphasized a number of significant points about the natural history of this benign parotid tumor.
The charts of all salivary-gland tumors were reviewed and traced for the ten-year period from January 1945 to the present. There were 95 patients who had parotid masses excised. Of the 95 patients, two had lymphoma, not confined to the parotid gland. Two patients had benign lymphoepithelial lesion which is probably not a true neoplasm.8 This left a group of 91 patients who had
