Comparative study of Cytodiagnosis of salivary gland neoplasm with histopathology
Introduction: FNAC is the largest tool in diagnostic pathology. Cancer is the leading cause of death in India. Salivary gland neoplasms accounts for 6% of all head and neck tumors. There are many advantages of FNAC. But in head and neck lesions, it is easily accessible, having excellent patient compliance, also a minimally invasive procedure and helping to avoid surgery in non-neoplastic lesions.
Aims and Objectives: To test the utility of FNAC, to establish the perfect diagnostic accuracy of cytology before operative procedure and also by comparison with histopathology diagnosis and also to establish the sensitivity and specificity of this technique in neoplastic lesions.
Material and Method: The present study was undertaken in the Pathology Department of GMERS medical college and hospital, Sola-Ahmedabad, Gujarat during the period of January 2015–June 2016.
Results: Among all salivary gland neoplasms, pleomorphic adenoma was the most common salivary gland neoplastic lesion (79.55%). Mucoepidermoid carcinoma was the commonest malignancy seen. Majority of malignancies were present in the 51-60 years age group (62.50%). The mean age of salivary gland neoplasms was found to be 41.59 years. Male to female ratio was found to be 1.2:1 and in malignant lesions the male to female ratio was 3:1.
Conclusion: Even though excision biopsy remains the gold standard for diagnosis of the salivary gland neoplastic lesion, cytological study can also establish the diagnosis of the majority of salivary gland neoplastic lesions and can be recommended as an adjunct and prior to histopathology.
