The Pathology of the Lungs in Five Nickel Workers

This investigation is to determine whether there are any characteristic pathological changes in the lungs of men employed in nickel refining. Five patients were available for study, four of whom had developed pulmonary carcinoma. All these men had worked at the same refinery. Previous pathological reports are scanty, but a few cases have been described by Amor (1939) and by L0ken (1950).
