Lymphoma of the parotid gland.

In a consecutive group of 452 patients undergoing parotid surgery at this institution, 18 (4%) were found to have lymphoma. Review and analysis of presenting symptoms, predisposing factors, histopathology, postsurgical morbidity, and long-term outcome with treatment are presented. The current literature on parotid lymphoma is reviewed, and management strategies are outlined. Although a relatively uncommon primary lesion, lymphoma must be considered in the differential diagnosis of any mass presenting in the parotid gland.
