J90-J94: Other diseases of pleura

J92: Pleural plaque

Pleural plaque is a condition that affects the pleura, a thin membrane that envelopes your lungs and lines the inside of your chest cavity. It is characterized by the formation of areas of thickened pleura, often caused by prolonged exposure to asbestos, a mineral fiber widely used in construction materials in the past. Over time, the inhaled asbestos fibers may cause pleural plaques to develop. These plaques are generally harmless and do not lead to lung cancer, but they are usually an indication that the person had considerable exposure to asbestos. Common symptoms associated with this condition are breathlessness, chest pain, and a dry cough, although many people experience no symptoms at all. The progression of the disease can result in difficulties in the respiratory system. However, complications are rare and the plaques themselves do not become cancerous.
