“Sarcoidosis is an inflammatory disease that can produce small clusters of cells called “granulomas” anywhere in or on the body, including internal organs and the skin. A multi-organ disease, sarcoidosis may affect a range of systems, including the nervous system, musculoskeletal system, lymph glands, lungs, skin, liver, spleen, eyes, heart, brain, and kidneys. In some cases inflamed granulomas may interfere with the functioning of an organ. The disease is not contagious.”.
