ABSTRACT Extrapulmonary tuberculosis associated with immune thrombocytopenia (ITP) is extremely rare. A likely association between ITP and pulmonary and lymph node tuberculosis was reported in a 29-year-old male patient. His platelet count decreased to 4,000/µL. Chest tomography revealed mediastinal adenomegaly, lymph node clusters in the aorta, and consolidation in the left upper lung lobe. Immunoglobulin and methylprednisolone were administered intravenously. The histopathology of the left upper lung lobe confirmed tuberculosis. The rifampicin/isoniazid/pyrazinamide/ethambutol regimen was initiated, and the corticosteroids were tapered off. This case suggests an association of tuberculosis with ITP, since the platelet count effectively normalized after tuberculosis treatment.

A doença pulmonar por metal duro é uma pneumonia intersticial por células gigantes relacionada com a exposição à poeira composta por metais duros. Neste artigo é relatado o caso de um profissional da indústria petrolífera, diagnosticado com doença pulmonar por metal duro com base na documentação clínica, radiológica, funcional pulmonar e anatomopatológica.

Hard metal lung disease, which manifests as giant cell interstitial pneumonia, is caused by exposure to hard metal dust. We report the case of an oil industry worker diagnosed with hard metal lung disease. The diagnosis was based on the clinical, radiological and anatomopathological analysis, as well as on pulmonary function testing.
