Spectrum of salivary gland diseases: A 24-year single-institution retrospective study.

Abstract

Salivary glands are exocrine glands and are classified as major and minor salivary glands. Salivary gland pathologies are classified as neoplastic and non-neoplastic. The neoplasms of salivary glands can be benign or malignant. The aim of the study was to describe the frequency of various salivary gland diseases reported in our institution from 1997 to 2021. This was a 24-year retrospective study of salivary gland lesions processed and reported by the Department of Oral Pathology and Microbiology. Data regarding age, gender, site, and diagnosis were obtained and studied. Amongst the total 5928 biopsied cases reported, 6% were salivary gland pathologies. Two hundred sixty-six were non-neoplastic lesions and 81 were neoplastic. The most common non-neoplastic lesion was mucous extravasation cyst. The most common neoplastic lesion was pleomorphic adenoma. The frequency of occurrence of salivary gland lesions in the last 24 years of this institution is almost similar to that stated in other published studies.
