Sarcoidosis is a disease characterized by the growth of tiny collections of inflammatory cells (granulomas) in any part of your body - most commonly the lungs and lymph nodes. But it can also affect the eyes, skin, heart and other organs.
Symptoms vary, depending on the organs affected. Sarcoidosis often goes away on its own. Minimal treatment is required in most cases. For some, it may last for years and lead to organ damage.
