Abstract: Abstract In view of the feature of biological behavior of behavior of mixed tumor arising from salivary glands from salivary glands which is plemorphic in histopathology and easy to recur after resection, a series of clinicopathological data of 127 cases of mixed tumor was reviewed with following up over 5 years in which 113cases were benign and 14 14 cases malignant. We put stress on camparision and analysis of generativecharactersitic and capsular feature of the primary tumor, and morphological index of main component form for tumor cells and intersitial composition.Statistic significance shows that rscurrent rateafter resection for multiple nodules of the primary tumor is higher obviously than single nodule.However, there is no differences for recurrent rate without intact capsule or local invasion of the tumor and with cell or mucoid and chondral composition dominant position.
