Abstract
One hundred two patients with parotid tumor were treated in the ENT Department, Kyoto Pref ectural University of Medicine between 1989 and 1994. Twenty-four of the 102 parotid tumors were Warthin's tumor (adenolymphoma). This incidence of Warthin's tumor was higher than that in any previous reports. This and other recent reports show that the incidence of Warthin's tumor has tended to increase recently, but the reason for this increase is not clear. In general, it is said that Warthin's tumor is found much more frequntly in males than in females, so we reviewed and analyzed 9 clinical cases of Warthin's tumor found in women. The average age of these women was approximately 10 years younger than that of male patients. No substantial differences were seen between male and female cases of Warthin's tumor on CT and Echo findings.
