Abstract

MELO, Allan Ulisses Carvalho de et al. Salivary gland neoplasms: a retrospective study of 134 cases in a population from the northeast of Brazil. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2012, vol.12, n.2, pp. 65-72. ISSN 1808-5210.

Aim: The aim of this study was to analyze the prevalence of salivary gland neoplasms diagnosed at Dr. Napoleão Laureano Hospital in João Pessoa-PB. Methods: The case files of patients diagnosed with salivary gland neoplasms between 1996 and 2003 were reviewed. Results: One hundred and thirty-four cases retrieved from the files were considered for analysis. Ninety-four neoplasms (70.1%) were benign and 40 (29.9%) were malignant. The patients' ages ranged from 9 to 97 years (mean, 44.1 y), and the largest proportion (25.2%) was in the 50-59 y age group. The malignant forms were most frequent in those aged 50-59 y and the benign ones in those aged 40-49 y. Ninety-one patients (67.9%) were women, with a female predominance for both benign (74.5%) and malignant (52.5%) neoplasms. The majority (82.9%) of the 76 tumors located in the parotid glands were benign. Pleomorphic adenoma was the most common benign neoplasm (83%), while adenoid cystic carcinoma was the most prevalent malignant one (60%). Conclusion: Women aged between 40 and 60 years were the most affected by salivary gland tumors, particularly pleomorphic adenomas among the benign ones and adenoid cystic carcinomas among the malignant ones, the parotid being the most affected gland.
