Nepheline rock dust pneumoconiosis. A report of 2 cases.

Abstract	Two cases of nepheline rock dust pneumoconiosis are presented. Radiologically, this is seen as a diffuse increase in interstitial lung markings, lymphadenopathy, air-space disease, and atelectasis secondary to extrinsic compression by enlarged hilar lymph nodes. Major differential diagnoses include carcinoma of the lung, sarcoidosis, and interstitial lung disease caused by other inorganic dusts. Nepheline rock dust pneumoconiosis should be considered when the above radiological changes are observed and an occupational exposure to inorganic dust is documented.
