Background Fine Needle Aspiration Cytology (FNAC) is a valuable diagnostic tool for evaluating lymph node swellings, providing insights into potential malignancies. Materials and methods This one-year retrospective study, conducted from July 2022 to June 2023, focuses on the reclassification of lymph node swellings at various anatomical sites using FNAC. We employ the Sydney System, a comprehensive five-tier classification system that emphasizes the Risk of Malignancy (ROM) within each category.
Results
The study encompasses 226 FNAC cases, primarily affecting individuals aged 26 to 45, with a gender distribution of 79 males and 147 females. The most frequently affected region was the neck, accounting for 85% of cases, followed by the axilla (8%), inguinal (3%), posterior auricular (2%), and occipital (2%) regions. It is important to note that histopathology reports were available for only 12 cases, and we acknowledge the limitation that ancillary tests for lymphoid malignancy diagnosis, such as flow cytometry and molecular studies, were not accessible.
Conclusion
This study underscores the significance of FNAC in lymphadenopathy evaluation, the utility of the Sydney System in providing structured ROM assessments, and the need for further diagnostic refinements.
