Acute silicosis responding to corticosteroid therapy

Abstract

The course of acute silicosis usually is relentlessly progressive. Death results from cor pulmonale and respiratory failure, with mycobacterial infection a frequent serious complication. Attempts to treat the illness generally have been unavailing. We report an unusual case of acute silicosis in which improvement in clinical status, chest x-ray film findings and pulmonary function occurred following therapy with corticosteroids. To our knowledge, this is the first such case reported in the medical literature.
