Histopathological study of salivary gland lesions-an institutional study

Abstract

Background: The salivary glands are the site of origin of a variety of neoplasm and are also relatively uncommon accounting for Materials and Methods: this study was conducted for two years (Nov 2018-Nov 2020) in the department of pathology KBNIMS, kalaburagi. Total number of salivary gland lesions included were 50. Specimens were processed and stained by hematoxylin and eosin stain followed by microscopic examination. Results: out of total 50 cases 54% were non neoplastic and 46% were neoplastic. Predominantly salivary gland lesions were found in the 3rd -4th decade. Male predominance was seen in all salivary gland lesions. In non neoplastic lesions chronic sialadenitis was predominant (32%) followed by mucocele (10%). In neoplastic lesions, Pleomorphic adenoma was commonest benign tumor accounting for 22%. Mucoepidermoid carcinoma was most common malignant salivary gland tumor. Most of the salivary gland lesions were found in the submandibular gland. Conclusion: Histopathological examination remains gold standard because of their varied histomorphological features Keywords: Sialadenitis, Salivary gland lesions, Pleomorphic adenoma, Mucoepidermoid carcinoma.
