Tuberculosis may coexist with malign diseases. Because of
the similar symptoms and signs, it is often difficult to diagnose
one from the other during the treatment period. In one
case report, a paratracheal mass was detected using thorax
computed tomography in a man with chronic hepatitis B
disease after a mediastinal enlargement was shown on his
chest X-ray. Histopathologic examination revealed necrotizing
granulomatous inflammation, supporting tuberculosis.
Then standard anti-tuberculosis treatment was initiated. At
the third month of therapy, the patient was admitted to the
hospital with swelling in his peripheral lymph nodes. Axillary
excisional biopsy was consistent with large B-cell lymphoma.
