Polymerase chain reaction to identify mycobacterium tuberculosis in patients with tuberculous lymphadenopathy.
Tuberculous lymphadenopathy is often diagnosed and treated on clinical and cytopathological grounds as Mycobacterium tuberculosis remains undetected in tissue specimens from such patients. At times, lymph nodes are known to respond sluggishly to and reappear during antitubercular therapy. We report a polymerase chain reaction-based approach to confirm the presence of M. tuberculosis in 4 such patients.
