Introduction: As a part of peripheral or secondary lymphoid organs, lymph nodes are a vital part of immune system. Their increase in size is referred to in a huge spectrum of diseases, inclusive of infections and malignancy, they may be a common finding in scientific practice. Therefore, peripheral lymph adenopathy is commonplace in all age groups and control of instances relies upon on lymph node pathology, which may be studied through collecting material via fine-needle aspiration or excision biopsy.

Objectives: Evaluation of the cytomorphological features and prevalence of various lymph node diseases on fine-needle aspiration cytology (FNAC)and to research the usefulness and diagnostic importance of FNAC in lymph node lesions.

Materials and Methods: Evaluation of one hundred cases with lymph node lesions at Department of Pathology in Rajah Muthiah medical college.

Results: Reactive lymphoid lesions comprised (33.69%) of cases, next to it was tubercular lymphadenitis, metastatic malignancies, acute suppurative lymphadenitis, and lymphomas, respectively.

Conclusion: Reactive lymphoid and tubercular lesions have been the most significant lesion of the lymph node swellings presentations. FNAC is a simple, safe, reliable, and cost-effective technique in early detection of lymph node lesions, which has been validated once more on this evaluation.
