Anthracosis pulmonum

This disease is caused by coal dust or soot and smoke that was absorbed, caught in the alveoli, and transported to the hilum and lymph nodes and deposited. The entire lungs are blackish gray. Among domestic animals, horses working in coal mines and dogs are frequently affected. This specimen represents the lungs and trachea of a lion during a performance.
