The characteristic cytological features of salivary gland lesions have been well described in literatures, but there also exist cytological diagnostic pitfalls that make it difficult to form an accurate diagnosis in some cases. To evaluate the sensitivity, specificity, positive predictive value and negative predictive value by Cyto- histological correlation with an emphasis on discordant cases. Retro-prospective study. 83 non- guided / palpable FNAC of suspected salivary gland enlargements were performed from 2016 to 2018 at tertiary care hospital of interior regions of kumaon. The cytological smears were stained with May Grunwald Giemsa, Papanicolaou, Hematoxylin Eosin stains. Surgically resected specimens were received for histopathology in 21 cases only. The cytologic and histologic slides were studied, compared and correlated where ever possible and statistical analysis done. Out of 83 patients male to female ratio was 1.44: 1. The different categories of salivary gland lesions included: non diagnostic, non-neoplastic, benign and malignant constituted 02, 34, 36 and 11 cases respectively. Pleomorphic adenoma and mucoepidermoid carcinoma was the commonest benign and malignant neoplasm reported in this study respectively. False negative and false positive results were mainly due to cystic and papillary lesions. The sensitivity, specificity, along with positive predictive value, negative predictive value of present study was 50 %, 94.11%, 67%, 88.88% respectively. Though palpable FNAC of the salivary gland tumors is simple, rapid and cost-effective in a developing country but rate of characterization of specific type of salivary gland tumor is lower due to overlapping cytomorphology.
