What is chronic sarcoidosis and can teenagers have it?

Sarcoidosis is a disorder that typically involves lymph nodes in the chest and sometimes the lungs as well. Teenagers can have it. It is typically diagnosed by biopsy showing the collection of abnormal cells, called granulomas. It can affect other tissues as well but the chest lymph nodes and lungs are the most commonly affected. There is treatment but not every case requires treatment. Good luck!
