Methods 120 inpatients of the tumors in parotid region with defined pathologic diagnosis were collected from 1995 to 2003. The retrospective analysis on the characteristic, tissue class of the tumors and the gender and age of patients was carried out. Results Among 120 cases, the radio of male to female was 1.07∶1.00, and the ages between 40 and 69 accout for the most, the patients of parotid tumor account for 76.67%, tumor inflammation for 12.50% and Tumor-like lesion for 10.83%. The radio of benign tumor to malignant was 5.57∶1.00. Pleomorphic adenoma is the most and Warthin tumor is secondary among the tumors. 27 cases (22.50%) of the tumor in parotid region were misdiagnosed as benign tumor, among which inflammation cases are most. All the cases were treated by surgery. Benign tumor and tumor-like lesion didn′t relapse during 2～5 years follow-up, whereas one case of malignant tumor did within 2 years. Conclusions The tumor in parotid region was delivered in middle age and old people so much. Benign tumor is the major type of the tumor in parotid region and should be distinguished from inflammation. In addition, the treatment strategy should base on the pathologic type and location of the tumor.
