Abstract
Silicotuberculosis is observed rarely in the current clinical practice. We present two patients (a 72-year-old man and a 84-year-old woman) who developed silicosis after having worked for several decades in the ceramics industry. In both, pulmonary tuberculosis complicated the clinical picture several years after retirement. The first subject presented a multicavitary lesion in the apex of the right lung, which subsequently evolved with fibrosis. The other developed bilateral tubercular bronchopneumonia and right tubercular pleurisy, that improved after prolonged antimycobacterial polychemotherapy. The two cases confirm that patients with silicosis are at an increased risk of developing tuberculosis, and show that, nowadays, silicotuberculosis may represent a geriatric problem. In the elderly, recognition of tuberculosis associated with silicosis is often difficult. Occupational history, radiology (conventional chest radiography and computed tomography) and microbiology (identification of Mycobacterium tuberculosis in sputum and pleural exudate) are helpful for the correct diagnosis, which, in turn, is important for prognosis and treatment, as well as in relation to medico-legal issues and occupational-related compensation claims.
