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.
