Angioimmunoblastic lymphadenopathy with dysproteinemia: thoracic involvement.

Angioimmunoblastic lymphadenopathy (AILD) is a rare condition, which is difficult to diagnose as it mimics tuberculosis or lymphoma both clinically and radiologically. A case of AILD with pulmonary involvement that was initially mistaken for tuberculosis on fine needle aspiration cytology and put on antituberculous treatment for three months, is presented here. The case was subsequently diagnosed to lymph node biopsy as one of AILD.
