Recurrent secondary spontaneous pneumothorax in silicosis: a case report.

Silicosis is an occupational lung disease which is caused by inhalation and accumulation of crystalline silica particles in the lung. It commonly occurs in workers involved in quarrying, mining, sandblasting, tunneling, foundry work, and ceramics. Pneumothorax is one of the complications of silicosis with pleural involvement. The occurrence of pneumothorax in a patient with silicosis is a rare event, but it may be fatal. The rate of pneumothorax recurrence in silicosis is usually low. We report a case of recurrent secondary spontaneous pneumothorax in silicosis.
