Abstract	Lymph node enlargement is commonly seen in clinical settings. But the diagnosis of lymphadenopathy merely by clinical judgement is difficult. Fine Needle Aspiration Cytology (FNAC) becomes a vital investigation tool for diagnosis of lymph node enlargement. It is safe, reliable, rapid, economic can be performed in outpatient department with minimal discomfort to the patient. The cytological diagnosis of lymph node lesions is extremely challenging for cytopathologist due to diversity of the diseases and coinciding cytomorphological features . Previously, there was no uniformity in reporting of FNAC of lymph node and there were no criteria’s given for reporting, due to lack of reproducibility which was creating confusion among clinicians . To overcome this pitfall, the Sydney system was recently introduced with categories for reproducibility and standardization of reports . It provides better communication between pathologist and clinician. It provides recommendation for each category and the calculation of Risk of Malignancy (ROM) related to each category of cytological diagnosis .
