CER-PNEUMOCONIOSIS

Abstract
The roentgenologic and biophysical findings of the previously unknown Cer-pneumoconiosis are reported. As a result of inhalation of the smoke of carbon arc lamps which produce a high quantity of dust, roentgenologically detectable morphologic changes of the lungs may occur, which, in their early stage, are shown as fine infiltrates which are well circumscribed and have a great density. They are disseminated throughout both lungs, and may be accompanied by fibrosis.The characteristic clinical and roentgenologic findings in 3 cases of a group of 67 exposed persons (60 of them working in graphic arts) are reported, and reference is made to the differential diagnosis from silicosis and other dust diseases as well as from specific and nonspecific miliary processes of the lung.
