Warthin's tumor, also called adenolymphoma, is a relatively rare tumor of salivary gland origin which occurs exclusively in the parotid glands, occasionally bilaterally.
The case presented is a 61-year-old male whose chief complaint was painless swelling of the right parotid gland. The swelling, though present for seven years, was untreated until he visited our hospital for the first time. We performed enucleation under general anesthesia. Histopathological study revealed papillary or tubular arrangement of necrotic columnar epithelium in lymphoid tissue with lymph follicules and island-or cord-like squamous metaplasia accompaned by cystic changes in the surrounding fibrous conective tissue. The case proved to be Warthin's tumor equivalent to subtype 4 by Seifert (1980).
The patient's postoperative course has shown no evidence of reccurence for four months.
