Milan system was introduced in 2018 with an objective to standardize and bring uniformity in the reporting of salivary gland lesion on fine needle aspiration. The present study is conducted retrospectively over a period of two years to reclassify salivary gland lesions according to Milan system and to calculate risk of malignancy in each category. Out of total 106 salivary gland aspiration cases, histologic follow up was available for 57 cases. On re-categorizing these lesions, maximum cases belong to neoplastic benign category. Risk of malignancy in each category were-non diagnostic (0%), non-neoplastic (25%), atypia of undetermined significance AUS (33.3%), neoplastic benign (5.3%), suspicious for malignancy (75%) and malignant (100%). Three false negative and one false positive case was identified in the study. In conclusion, Milan system is very helpful in providing a uniform reporting system for salivary gland lesions, enhancing diagnostic accuracy and providing valuable impact on their management.
