enlarged lymph nodes

my 29 son was diagnosed with sarcoidosis in oct 2002 by having parotitis, iritis,vertigo ,tinnitis, bilateral adneopathy and a high ace. the doctor thought watchful waiting was appropriate. the doctor waited a year and at first he thought the nodes had grown but a cat scan showed they were the same with a small cluster of granules in his lung. the doctor now is going to wait another year.the doctor said if it were his son he would not put him on predisone.I was surprised he did not order any blood work.I think my son is the only patient he has had with sarcoidosis. my question is should my son be on some sort of treatment? i just do not want to miss the boat. thank you very much.

Sarcoidosis is a disease that causes small clusters of inflammation, called granulomas.  The granulomas can occur in any area of the body, but are most common in the lungs, lymph nodes, eyes, and skin.  When the inflammation occurs in the lungs it may show up as cloudy areas on the CT scan.

Inflammation in the lungs can cause shortness of breath, wheezing or cough, often a dry cough.  In some people, the symptoms go away completely with or without treatment.  In other people the inflammation leads to permanent scarring or fibrosis.  There is no way to predict the chances of fibrosis for a particular individual.  The cause of sarcoidosis is unknown.
