Most people think of rheumatoid arthritis as a condition that affects only a person’s joints. But that isn’t always the case. Extrarticular manifestations in the lungs can be an especially serious problem. A study by a group at Mayo Clinic found that about 1 of every 10 people with RA will develop a type of serious lung complication called interstitial lung disease. ``Most often lung diseases will be related to inflammation of an area of the lung,’’ said Eric Matteson, M.D., chair of the Division of Rheumatology at Mayo Clinic in Rochester, Minn.
