Occupational lung fibrosis in an aluminium polisher. 
An aluminium polisher developed severe lung fibrosis complicated by bronchial carcinoma.  Although he was not submitted to the exposure risks usually described in aluminium lung (bauxite smelting, use of aluminium powders, aluminium welding), he worked in a high concentration of aluminium dust.  This was demonstrated by mineralogical analyses which revealed large amounts of small metallic aluminium particles (0.5 micron - 5 micron) in bronchoalveolar lavage, lung tissue and lymph nodes 5 years after the end of exposure.  Aluminium polishing seems to be a potential cause of aluminium lung.
