Abstract :

 INTRODUCTION: Tuberculosis is an important cause of morbidity and mortality in developing countries. Tuberculous lymphadenitis is the most common form of extrapulmonary Tuberculosis. Proper diagnosis and prompt treatment of Tuberculosis is very important. This study will emphasize the role of FNAC in the diagnosis of Tuberculous lymphadenitis and the importance of techniques like AFB staining and CBNAAT in diagnosing equivocal cases   OBJECTIVES: To study the incidence of tuberculosis among the cases of peripheral lymphadenopathy, to study the various cyto–morphological patterns of tuberculous lymphadenitis and to emphasize the importance of AFB staining & CBNAAT in the correct diagnosis of tuberculosis.   MATERIALS AND METHODS: A retrospective study is carried out for a period of one year. FNAC was done for 547 patients with peripheral lymphadenopathy The cyto–morphological pattern of these cases are presented along with AFB positivity and detection of Mycobacterium Tuberculosis by CBNAAT. RESULTS: Out of  547 patients with superficial lymphadenopathy, 177 cases were diagnosed as Tuberculous lymphadenitis. The ratio of males to females was 1: 1.5. There were maximum number of cases in the age group of 31– 40 years.  Among the cases of Tuberculosis, there were 29 cases of granuloma without necrosis, 99 cases of granuloma with caseation necrosis, 18 cases of caseation without granuloma and 29 cases of caseation with abscess without granuloma. Overall 76 (42.9%) cases were positive for AFB. CBNAAT was positive in 18 cases. CONCLUSION: Fine needle aspiration cytology (FNAC) is a safe and simple investigation used to diagnose Tuberculous lymphadenitis. Demonstration of the presence of Acid fast bacilli by Fluorescence microscopy,  Zeihl–Neelsen staining and the CBNAAT improves the sensitivity and specificity of FNAC.
