Pulmonary melioidosis complicating foreign body aspiration in a young adult

Melioidosis is caused by an environmental Gram-negative bacilli Burkholderia pseudomallei. Diabetes mellitus, occupational exposure to soil and water, pre-existing renal diseases and thalassemia are significant independent risk factors for melioidosis. A 30-year-old male carpenter and smoker had a history of accidental aspiration of foreign body 2 months prior. On presentation, he had cough with expectoration and low-grade intermittent fever for 1 month. His chest x-ray displayed left lower zone consolidation with cavitation and presence of foreign body in the left lower lobe bronchus. Bronchoalveolar lavage inoculated onto 5% sheep blood agar and MacConkey agar grew B. pseudomallei. Melioidosis due to foreign body aspiration is rare. To the best of our knowledge, there have not been reports of melioidosis infection associated with foreign body inhalation. Hence, pulmonary melioidosis can be considered as a differential diagnosis in cases of foreign body with secondary infection even in immunocompetent host.
