title: Unilateral multicentric Warthin's tumors.
abstract: Papillary cystadenoma lymphomatosum, or Warthin's tumor, is known to have a high rate of multicentricity. An incidence of 5-14% is suggested by the literature. We present a female patient with three discrete masses noted in the superficial lobe of the parotid gland at the time of surgical resection. The epidemiology, histology and pathophysiology of Warthin's tumor is discussed and the need for adequate surgical resection is emphasized.
