A case of rush dust (“Igusa Sendo”) pneumoconiosis

Abstract

Background : We report a case of rush dust (dust of clay to dye Igusa) pneumoconiosis, in which broncho alveolar lavage fluid cytology revealed asbestos bodies and silica crystals.

Case : A man in his 70’s who had worked as a rush farmer for more than 40 years.

Conclusion : Careful observation of the bronchoalveolar fluid cytological specimens for the presence of both asbestos bodies and silica crystals could lead to a precise diagnosis of rush dust (“Igusa Sendo”) pneumoconiosis.
