Salivary gland neoplasms: an analysis of 74 cases

Between 2006 and 2009, 74 cases of salivary gland neoplasms were analyzed retrospectively, of which 44 (60%) were benign and 30 (40%) malignant. 61 % percent of neoplasms were in the parotid gland, 22% in the minor salivary glands including sublingual salivary glands, and 17% in the submandibular glands. The most common benign neoplasm was pleomorphic adenoma (64%), and the most common malignant neoplasm were adenoid cystic carcinoma (17%) and mucoepidermoid carcinoma (23%). We analyze the incidence and distribution of all types of salivary gland neoplasms in our series, and provide data for comparison with other epidemiological studies from different geographical sites and races. Demographic data from these studies help us to a better understanding of the biological and clinical characteristics of the disease. Further epidemiological surveys should be encouraged for better understanding of the disease and to provide early and better treatment of salivary gland neoplasms.
