Abstract : Fine needle aspiration is the mainstay in the diagnosis of Lymphadenopathies. In present study the purulent aspirates from lymph nodes were evaluated for etiological agents to know the distribution pattern of various disease agents. Materials and Methods: This study was a prospective one covering 100 cases taken from patients attending MBS and NMCH Hospitals under Govt. medical college, Kota. Our study spanned from January to December, 2017. Results and Conclusion: Out of a total of 100 cases incidence of different types of lymphadenopathies were, Tubercular, 55%, Acute suppurative, 27%, Granulomatous Inflammatory, 12% and Metastatic Carcinoma, 6%. Cases of lymphadenopathy showed a wide age range from 1 to 73 years. Male to female ratio was 1:1.04. AFB positivity was seen in 61.8% cases of Tubercular lymphnoditis. Among the 55 cases of tubercular lymphnoditis, 46 (83.6%) cases showed Auramine Rhodamine positivity while only 34 (61.8%) corresponding cases were positive by Ziehl Neelsen stain, demonstrating higher sensitivity of Auramine Rhodamine stain. In present study, commonest cause of Metastasis in lymph nodes was Squamous Cell Carcinoma (33.3%). Other diagnosis were Metastatic Adenocarcinoma, Duct carcinoma breast, Mucoepidermoid carcinoma and poorly differentiated carcinoma. On gram’s staining out of 27 cases of Acute suppurative lymphnoditis, 3 showed positivity for gram positive cocci. Out of 3 cases, 1 case showed gram positive cocci in clusters and 2 cases showed gram positive diplococci. Diplococci were more common in younger population. FNAC is a safe, convenient, rapid and inexpensive first approach procedure, without any complications in evaluation of cases of lymphadenopathy and can be practiced even in peripheral hospitals where histopathological techniques are not available.
