Infección pulmonar inusual

Lung Actinomycosis. Uncommon pulmonary infection A 52-year-old male patient with history of type 1 diabetes presented productive cough for a period of three months, progressive exertional dyspnea and isolated episodes of hemoptoic expectoration. Physical examination evidenced percussion dullness in the right lower lung field and a decrease in breath sounds in the right infra-axillary region. Chest X-rays during the two previous months and a chest computerized axial tomography revealed a heterogeneous opacity in the middle lobe. A fiberoptic bronchoscopy with bronchoalveolar lavage and transbronchial biopsy was performed. The anatomopathological examination showed purulent exudates with microbial colonies consistent with actinomycosis. The patient was treated with intravenous penicillin G.
