The histological pattern of the lung was examined in 17 arc welders, who died of extrapulmonary diseases (6 cases), respiratory failure (2 cases) and pulmonary or pleural neoplasms. The most significant features observed were: anthracosiderosis, periarteriolar and peribronchiolar lymphocytic or plasma cellular infiltration, interstitial fibrosis of various degree and diffusion, irritative alveolitis or epithelization, bronchitis and peribronchitis. Arc welder's lung disease may no longer be considered as a simple siderosis and it is now known that welding fumes have a complex composition and exercise multiple action on the respiratory apparatus. The high frequency of malignant association in these cases (pulmonary cancer in 8 and pleural mesothelioma in 1) justify the suspect of a relationship between tumors and occupational exposure, as has been suggested in previous literature. The concausal risk factors (asbestos, smoke) are considered.
