Abstract

The aim of this study was to evaluate the demographic and clinicopathologic data of salivary gland tumors managed at a tertiary referral medical center in Turkey. The data of 510 patients with salivary gland tumors managed during the period of January 1984 to May 2012, were reviewed. Only primary neoplasms derived from salivary glands were included. Out of 510 neoplasms, 352 (69.0 %) were classified as benign and 158 (31.0 %) were classified as malignant. There was a male predominance and male: female ratio was 1.23 (281/229). The most common location was parotid gland (372/510, 72.9 %) followed by minor salivary glands (97/510, 19.0 %) and submandibular gland (40/510, 7.9 %). The malignancy rates were 21.5, 40.0, and 56.7 % in parotid, submandibular, and minor salivary glands locations, respectively. The most common location for minor salivary gland neoplasms was oral cavity (61/97, 62.9 %). Pleomorphic adenoma (PA) was the most common histopathological type (45.3 %) in the whole study group and also among pediatric patients. The most common malignant neoplasms were adenoid cystic carcinoma (39/510, 7.6 %) and mucoepidermoid carcinoma (5.7 %). Salivary gland tumors are more common in men. The malignancy rate is almost three times higher in neoplasms derived from minor glands when compared to parotid gland. PA is the most common histopathological tumor type in all locations and in all age groups.
