The natural history of sarcoidosis is very variable, with approximately two-thirds of subjects showing spontaneous remission and only 10% to 30% of patients showing a chronic or progressive form. The most important factor in determining treatment for sarcoidosis is whether there is a risk of death, organ failure, or loss of quality of life. Glucocorticosteroids are the mainstay of treatment, and if the disease progresses despite treatment, or if glucocorticosteroids cannot be reduced or cannot be used, immunosuppressants such as methotrexate and azathioprine can be considered.
