Sarcoidosis is a disease that occurs when areas of inflammation develop in different organs of the body. Very small clusters of inflammation or white cells, called granulomas, are seen in the organs affected with sarcoidosis. They may occur in the lungs, lymph nodes, eyes, skin or any area of the body. These granulomas may clear up on their own, or cause permanent scarring.
