The Rare Imitator : Pulmonary Nocardiosis Mimics Tuberculosis Reactivation

Pulmonary Nocardiosis is a rare bacterial infection of lungs, caused by a filamentous bacterium. Immunocompromised people are known to be at danger, but there are other new emerging risk factors to consider. The presentation and clinical course in such patients differ from the previous. Here the present case is aimed to underline the presentation and diagnosis in non-risk individual.

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.
