Study of histomorphological patterns of salivary gland tumors

Introduction: Salivary gland neoplasms though relatively rare, have a varied histological spectrum both in the benign and malignant tumors and hence, are of interest to pathologists. Aim of the study: To study the histomorphological patterns of salivary gland tumors. Materials and Method: This was a two year four month prospective study from January 2015 to April 2017. The salivary gland specimens received in histopathology section of Department of Pathology, Government Medical College, Nizamabad, Telangana were studied for light microscopy. Results: Present study included 80 cases, with patient age ranging from 11 to 78 years and the male to female ratio was 3:1. In the present study 62.5% cases were benign and 37.5% were malignant. Pleomorphic adenoma was the commonest benign tumor followed by Warthin’s tumor, monomorphic adenoma and basal cell adenoma. Mucoepidermoid carcinoma was the most common malignant tumor followed by adenoid cystic carcinoma, acinic cell carcinoma and carcinoma ex pleomorphic adenoma. Conclusion: Of all salivary glands, Parotid glands are most commonly affected by tumors. Pleomorphic adenoma is the most common benign tumor and Mucoepidermoid carcinoma is the most common malignant tumor in salivary glands.
