The case history is presented of a 70-year-old male patient with a papillary cystadenoma lymphomatosum of the parotid gland. The patient had had a non-tender, hen's egg sized, firm swelling at the angle of the left mandible for about 2 years. Sialogram revealed a filling-defect with displacement of ducts in the inferior portion of the glandular area. Removal of the encapsulated tumor from the deeper lobe of the parotid gland was accomplished without any complication. The literature relating to this relatively rare tumor is reviewed. Statistically the tumor occur most commonly at or below the angle of the mandible in the tail of the parotid gland of middle-aged males. It is generally accepted that the tumor is a benign neoplasm composed of epithelial and lymphoid elements and cannot be distinguished clinically from the relatively common mixed parotid tumor. Surgical excision is the only effective form of treatment. Complete surgical extirpation of the tumor is seldom followed by recurrence. But the follow-up period in this case has been too short for adequate evaluation of therapy. The theories on origin of the tumor and its clinical and pathological characteristics have been discussed.
