What is sarcoidosis?

Sarcoidosis (say "sar-coy-doe-sis") is a disease that can affect any organ or system in the body. People with sarcoidosis develop granulomas (small abnormal clumps of tissue) in certain parts of their body. If you have this disease, you may have no symptoms at all, or you may have serious problems with many different parts of the body. The exact cause of sarcoidosis is unknown.

Sarcoidosis is most common in adults between 20 and 40 years of age. It's more common in women than in men. Worldwide, it occurs more often in African Americans and northern Europeans, especially people from Scandinavia. Sarcoidosis is not contagious. This means you can't catch sarcoidosis from another person who has the disease.
