Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 5
Abstract
Background: Fine need aspiration cytology is the gold standard investigation in the work up of salivary gland tumors. This is one of the fast and cost effective investigations available. With the widespread availability of FNAC, the place of incisional biopsy is limited to only a few condition like direct skin infiltration and for minor salivary gland swellings. However, the interpretation of FNAC is subjective. We conducted this study to describe the pattern of FNAC findings in a cross section of patients diagnosed to have salivary swelling. Method: This study was done in the department of surgery medical college, Trivandrum during 1996 to 1998. All patients presented with salivary gland swelling were included except those with a history of neck irradiation, recurrent swelling, pediatric patients and those with skin involvement. FNAC was done following a standardized procedure as described in literature. Thereafter smears were prepared and cytological features were studied. Basic demographic variables were collected for the study. Statistical analysis were carried out in graphpad Instat and R statistical software. Results: There were 122 patients, 76(62.3%) being males. Most of the males were in the 30-60 age group. Polymorphic adenoma constituted the majority of the cytological diagnosis(29.5%). Of the total patients,104(85.2%) were treated surgically for various indications. The FNAC and histopathological features in the Post-operative specimen were comparable in most of the cases. Discussion: We analyzed the pattern of cytological features of salivary gland swellings presenting in our institution in this study. Our study showed that the clinical features of benign tumors had a definite bearing on the final histopathological type and therefore can be used as a reliable guide for the preoperative diagnosis and treatment of salivary gland swelling. But for malignant swelling, the clinical features and the final histopathological diagnosis differed significantly. Our study has shown that fine needle aspiration cytology has a marked diagnostic significance in the management of salivary gland swellings. It improves the management of salivary gland swellings positively.
