Mediastinal melioidosis: A case series from far North Queensland.

Melioidosis is the clinical disease caused by the Gram-negative bacillus and is endemic to Northern Australia and Southeast Asia. It is commonly referred to as the 'great mimicker' because of its wide range of clinical presentations, often making diagnosis challenging. Isolated mediastinal lymphadenopathy as the presenting feature of melioidosis is rare and can be indistinguishable from tuberculosis or malignancy.
