RESUMEN
Introduction:Lymph nodes are the most widely distributed and easily accessible component of lymphoid tissue. Alarge spectrum of diseases including reactive processes,infections, lymphomas and metastatic tumors can cause lymphdeopathy. FNAC is used as a triage to distinguish between cases of lymphadenopathy with high or low level of level suspicion of significant disease and thus an immediate decision can be made wheather to simply observe the node,to recommend a course of antibiotics,or to refer the patient to a specialist for further investigation.Objective: The present study has been undertaken to study the different cytomorphological patterns associated with various lymphadenopathies and the role of FNAC in detecting lymph node lesions. Materials and Methods:Aretrospective study of 117 cases of lymphadenopathy was carried out in the department of pathology. FNAC smears were carefully studied and categorized into non neoplastic and neoplastic lesions.Result:Our of 117 cases,98 cases(83.76%)were non-neoplastic and 12 cases(10.25%) were neoplastic. 7(5.98%) were inconclusive for opinion.Out of the non neoplastic lesions, reactive lymphadenitis was the most common diagnosis(56/98,57.14%).Among the neoplastic lesions, metastatis was the most common diagnosis (9/12,75%).Sensitivity, specificity and diagnostic accuracy was 83.33%,100% and 83.33% respectively.Conclusion:Fine needle aspiration cytology plays a important role in the diagnosis and management of the various lymphadenopathies
