Sarcoidosis is a disease that forms round spots called granulomas in organs in the body. The most common places they form are in the lungs and lymph nodes.


Inflammation is how the body acts toward an infection or injury. Inflammation should go away when you are healed. Inflammation does not pass in people with sarcoidosis. The cells that cause it stay and cause granulomas. It is not known why this happens. It may be due to genetics or the environment.
