Abstract :

BACKGROUND: Tuberculosis is one of most common infectious diseases in India, which is causing economic burden despite being easy in diagnosis and treatment. India has the highest burden of tuberculosis according to WHO, 2017 estimates (2.79 million out of 10.4 million world wide).

PATIENTS AND METHODS: Fine needle aspiration cytology for peripheral lymphadenopathy, east lesions, thyroid lesions and superficial swellings were done using Ziehl–Neelsen (ZN) stain for a period of one year between March 2016 to Feuary 2017 in the department of Pathology.

RESULTS: Out of 132 cases 21.21% showed positive for acid fast bacilli. Lymphnodes constitute majority of the cases followed by Breast abscess.

CONCLUSION: ZN stain plays a major role in confirming the diagnosis of extra pulmonary tuberculosis. Thus recommending implementation of mandatory ZN staining for all the FNAC cases for better and confirmed diagnosis of extra pulmonary tuberculosis cases and also provides a ready reference to decide whether the sample has to be sent for testing MDR TB.
