J92: Pleural plaque

J92.0: Pleural plaque with presence of asbestos

The lungs are surrounded by a smooth membrane. A smooth membrane like this is also located inside the ribs. Both membranes cling to each other via a small amount of fluid. Through the suction of the fluid between the membranes, the lungs follow the movements of the chest while breathing. The lungs then alternately expand and contract. Air for breathing flows into the lungs and out again during these movements.

You inhaled many asbestos fibers in the past. These asbestos fibers can be deposited in the lungs and membrane around the lungs. The tissue in the lung membrane is reacting to the asbestos fibers. The cells in the lung membrane are then releasing substances. These substances have caused the smooth membrane around your lungs to be thickened.
