The aim of this study was to determine the distribution and demographic features of salivary gland tumors (SGTs) in a large Brazilian population.
A total of 493 cases of SGTs diagnosed between 2001 and 2011 from a general pathology laboratory and an oral pathology service were reviewed with respect to their clinicopathologic features.
A total of 369 tumors were benign and 124 were malignant. The mean age of patients with benign tumors was 46.3 years and that of patients with malignancies was 54.0 years. The parotid gland was the most common location (42.3%). Pleomorphic adenoma (PA) and Warthin's tumor were the most common benign neoplasias, whereas mucoepidermoid carcinoma (MEC) and adenocarcinoma, not otherwise specified, were the most frequent malignancies.
The present data confirm that PA and MEC are the most common benign and malignant SGTs. However, it is important to consider that differences in tumor types may be influenced by whether a tumor derives from a medical or a dental service.
本研究旨在确定大型巴西人群中唾液腺肿瘤（SGT）的分布和人口统计学特征。
回顾了 2001 年至 2011 年间来自普通病理实验室和口腔病理服务的 493 例 SGT 的临床病理特征。
共 369 例为良性肿瘤，124 例为恶性肿瘤。良性肿瘤患者的平均年龄为 46.3 岁，恶性肿瘤患者的平均年龄为 54.0 岁。腮腺是最常见的部位（42.3%）。多形性腺瘤（PA）和沃辛瘤是最常见的良性肿瘤，而黏液表皮样癌（MEC）和非特指腺癌是最常见的恶性肿瘤。
本研究数据证实，PA 和 MEC 是最常见的良性和恶性 SGT。然而，需要注意的是，肿瘤类型的差异可能受到肿瘤来自医疗服务还是牙科服务的影响。
