title: Hard metal pneumoconiosis with spontaneous bilateral pneumothorax.
abstract: Hard metal pneumoconiosis, first described in 1964, is a diffuse disease caused by the inhalation of cobalt particles. The disease can manifest as occupational asthma, interstitial disease or allergic alveolitis. We report the case of a young male, working as a tool sharpener, who presented with dry cough and progressive dyspnea for one year, as well as with spontaneous bilateral pneumothorax at admission. The diagnosis was confirmed by open lung biopsy.
