Implication

Case series demonstrates non-beryllium metal dust accumulation in occupational granulomatous lung disease, highlighting aluminum toxicity as an underrecognized cause of lung granulomas.

Key Points

Investigate metal dust deposition and elemental composition in lung tissue of workers presenting with non-beryllium occupational granulomatous lung disease.
Evaluated two workers with chronic occupational metal dust exposure (battery manufacturing for 7 years and aluminum processing for 6 years) who presented with diffuse pulmonary micronodules on chest computed tomography.
Analyzed video-assisted lung biopsy specimens using routine histopathology, pathogen-specific staining, and two-dimensional elemental mapping via an electron probe microanalyzer with a wavelength-dispersive spectrometer (EPMA-WDS).
Histopathologic analysis revealed interstitial granulomatous lesions, with negative stains for fungal and mycobacterial infections.
EPMA-WDS confirmed localized deposition of silicon, iron, titanium, and high concentrations of aluminum within the granulomatous lesions, demonstrating clinical features similar to chronic beryllium disease.
