A case of tracheobronchopathia osteochondroplastica in a patient with silicosis is reported, showing a rare association of disease. Etiological hypotheses and clinical aspects are discussed. Radiologic, bronchoscopic, and pathologic findings are demonstrated with emphasis on the role of computed tomography (CT) in the diagnosis of this disease.

A case of broncholithiasis associated with massive silicosis is reported, showing a rare aspect of parenchymal lesions generating broncholiths as well as the presence of recurrent lithoptysis, with subsequent regression of radiological lesions. Aetiological, clinical, physiopathological, and radiological aspects of the disease are discussed, demonstrating the importance of the use of computed tomography in diagnosis. The mineralogical analysis of expectorated fragments is also shown.
