Lung Sarcoidosis Underlying Cause
Sarcoidosis results from an abnormal immune system, which normally fights infection. The immune system mistakenly attacks normal tissue, causing inflammation in the skin, lungs, liver, eyes, lymph nodes, heart, nerves bones, and joints. However, the most common location for sarcoidosis is the lungs. The cause of the abnormal immune system in sarcoidosis is unknown.
