Cytopathological categorization of salivary gland lesions according to milan system of classification: Our experience in a tertiary care centre of North-East India

Abstract

: Fine needle aspiration cytology is a widely accepted pre-operative procedure for salivary gland lesions. The aim of this study to evaluate the salivary gland lesions in relation to age, sex, location and the prevalence of non-neoplastic and neoplastic lesions that presented to Gauhati Medical College and Hospital (GMCH), Guwahati,: A retrospective study was done over a period of 2 years, from January,2019 to December,2020 and the slides and data of 110 cases of salivary gland lesions that underwent FNAC in our hospital(GMCH) were reviewed.: Out of a total of 110 cytological smears, 101 smears (91.9%) were adequate and 9 smears (8.1%) were inadequate. Out of 101 adequate smears, 35 (34.6%) were non-neoplastic lesions, 37 (36.6%) were benign and 29 (28.7%) were malignant lesions. Males were more commonly affected (M:F=1.6:1). Parotid gland was most commonly affected in relation to anatomical site. Most common benign lesion was Pleomorphic Adenoma and Mucoepidermoid carcinoma was the most common malignancy.: FNAC is a very reliable, cost-effective, safe and rapid diagnostic tool for categorizing malignant and benign salivary lesions which is complimentary to histopathology. Though histopathological examination remains the gold standard for diagnosis, FNAC remains an useful adjunct for planning patient management.
