Fine Needle Aspiration Cytology of Parotid Lesions: A Study of 84 Cases with Special Reference to Cyto-Histological Discrepancy
Journal Title: International Journal of Medical Research Professionals - Year 2017, Vol 3, Issue 2
Abstract
Background: Parotid gland lesions are extremely diverse entities. Pre-operative cytodiagnosis is difficult due to heterogenesity of cellular components. However pre-operative FNAC as a diagnostic tool is till controversial. Aims: The study was performed to evaluate the effectiveness of FNAC in preoperative diagnosis of parotid lesions and to evaluate the cases of cyto-histological discrepancies. Material & Methods: The study was conducted over a three years period over 84 cases of parotid lesions, where cytological diagnoses were compared with histopathological report in available cases. In all cases of cyto-histological discrepancies, possible causes of discrepancies were searched. Results: Non neoplastic (23 cases, 29.48%) and benign (40 cases, 51.28%) cases outnumbered than malignant tumors (14 cases, 19.23%). Diagnostic sensitivity and specificity of cytology were 86.66% and 95.74% respectively. We found six cases of cyto-histological discrepancies with a diagnostic accuracy of 93.54%. Two false negative, two false positive cases were evaluated and two cases had error in typing of tumor. Conclusion: Many of parotid tumors have one or more close cytologic mimickers due to diverse cell types and growth pattern. However FNAC should be primary evaluating tool for diagnosis and management of parotid lesions.
