Comparison of conventional Ziehl & #8211;Neelsen method of acid fast bacilli with modified bleach method in tuberculous lymphadenitis

Conclusion: There are problems in arriving at an absolute diagnosis in certain cases of tuberculous lymphadenitis when the aspirate shows polymorphous picture with occasional epithelioid cells and absence of typical Langhans giant cell or caseous necrosis. In the present study, acid fast bacilli positivity was established in 65.33% of the cases with the bleach method. Bleach method for detection of tubercle bacilli has a high case detection rate than that of the conventional Ziehl–Neelsen method.
