A new era of coal workers' pneumoconiosis: .

Coal workers' pneumoconiosis (CWP) was suspected, but because of his relatively young age and short mining tenure, a transthoracic, CT-guided biopsy of his lung mass was done. Histopathological examination showed areas of focal collagenous fibrosis associated with anthracosis and polarised silicate particles; there was no evidence of cancer, granulomas, vasculitis, or infection ( figure ).
