Sarcoidosis is a rare disease where small lumps form in the body. The lumps are called granulomas. They can lead to inflammation in the tissue. The lumps are most common in the lungs and lymph nodes. However, they can form in any part of the body.
The condition can range from mild to life-threatening.
The exact cause of sarcoidosis is not known. It is likely due to genes and the environment.
Things that raise the risk of sarcoidosis are:
A family history of the condition
Working in certain jobs, such as:
The U.S. Navy
Handling building supplies
Sarcoidosis may not cause symptoms at first. Symptoms that happen depend on the organs involved. Symptoms may be:
Swollen lymph nodes
Fever or night sweats
Skin bumps or rashes
Headache, lightheadedness, or drooping of the face
