A case of silicosis showing multiple pathological lung changes

Each year the Northern Rhodesia Silicosis Medical Bureau examines about 4,000 European and 30,000 African miners employed in the Copper Mines. An examination includes a radiograph of the chest. Although different lung diseases are occasionally encountered, the main pathological disorder seen is silicosis or tuberculosis or a combination of both.
