Clinicopathological Analysis of 2489 Cases of Salivary Gland Epithelial Tumours

Objective: To investigate clinicopathological characteristics of salivary gland epithelial tumours.Methods: 2489 cases of salivary gland epithelial tumours were statistically analysed.Results: Adenoid cystic carcinoma,mucoepidermoid carcinoma and carcinoma ex pleomorphic adenoma were the mostly encountered three types in 840 cases of malignant epithelial tumours,while pleomorphic adenoma,Warthin tumour and basal cell adenoma were the mostly encountered three types in 1649 cases of benign epithelial tumours.The ratio of male to female of malignant and benign epithelial tumours was 1.13:1 and 0.99:1,respectively.The average age of malignant and benign epithelial tumours was 47.86 and 44.86 years old,respectively.Parotid gland and palate were the most common locations of salivary gland epithelial tumours.Conclusion: Adenoid cystic carcinoma and pleomorphic adenoma are the most common type of salivary gland malignant and benign epithelial tumours,respectively.
