title: Mica dust as a cause of severe pneumoconiosis.
abstract: BACKGROUND
  Mica exposure is frequent in mines, mills, agriculture, construction, and industry. This is a case report of possible mica pneumoconiosis.
  
  
  METHODS
  Case report and description of pathology. Histology slides were subjected to spectroscopic examination.
  
  
  RESULTS
  Fibrosis in the presence of mica, without evidence of silica was confirmed.
  
  
  CONCLUSIONS
  This report indicates that mica exposure may result in mica pneumoconiosis.
