CLINICOPATHOLOGICAL PATTERNS OF MINOR SALIVARY GLANDS TUMORS: A 16- YEAR RETROSPECTIVE REVIEW CARRIED OUT AT A SINGLE INSTITUTE IN NORTHERN JORDAN

Abstract

Minor salivary gland tumors (MSGTs) are relatively uncommon head and neck tumors with variable histological types. The primary purpose of this study was to explore the clinicopathological patterns of minor salivary gland neoplasms in the north Jordanian population and to compare them with findings from previous literature.

In this study, histopathological records of minor salivary gland tumors treated from January 2004 to December 2019 at the oral and maxillofacial surgery department, Prince Rashid Bin Al-Hassan Hospital, Irbid, Jordan, the main hospital in northern Jordan were reviewed.

The final sample showed 30 MSGTs ,17 of which were benign (56.66 %), and 13 were malignant (43.34%). There was male predominance (60%) with a male to female ratio of 1.5:1. Patient’s ages ranged from 25 to 86 years, with a median age of 49.37 ± 18.70 years. Pleomorphic adenoma was the most frequent tumor, making up 50% of all MSGTs. Adenoid cystic carcinoma was the 2nd frequent tumor representing 26.68 % of all MSGTs. The Palate (47%) was the most commonly involved site, followed by the upper lip (30%).

The current review found that MSGTs are uncommon in the northern Jordan population, and there is a relatively higher percentage of benign tumors. Unlike most previous studies, males were more affected than females.
