Background: The lymph nodes are an integral component of the immune system and their enlargement is a common presentation in the clinical practice. FNAC of lymph nodes are a very useful and simple tool in the diagnosis of lymph node malignancies. It may be the only tool in the diagnosis of metastatic lesions in the lymph nodes and can help to detect occult primary malignancies. The objective of this study is to describe the cytomorphologic features of various lymph node pathologies on fine-needle aspiration cytology (FNAC), to tabulate the cytological findings into neoplastic and non-neoplastic pathology and to determine the most common morphological pattern of lymph node pathology. Methodology: Ambi-directional descriptive study was done over a period of 1 year and 70 samples who fit into the inclusion criteria were included. The cytopathological reports of the 70 FNAC study cases were collected, categorized and compiled. Results: The mean age of the study participants was 37.43±21.26 years. Majority (45.7%) of the participants were found to be in the age group of 19-45 years. Of the total sample studied, prevalence of malignant disorder was found to be 13(18.5%). All the malignant lesion were in people above 45 years of age except for 2 cases of squamous cell carcinoma observed in a 32 and 38 year old male. It was observed that the benign lesion is more common in the younger age group and the risk of malignancy increases with increase in age. Conclusion: FNAC being the most common investigation done, is important for both appropriate risk stratification and for guiding the clinical management. Differentiation of neoplastic and non-neoplastic cases significantly reduces unnecessary surgical biopsy for diagnosis of lymphadenopathies.
