In some cases, mediastinal lymph node enlargement occurs due to secondary lung cancer when metastatic cancer spreads from another part of the body to the lungsand then to the lymph nodes. Glands usually secrete a fluid; for instance, the lacrimal glands above the eyeballs secrete tears and the pituitary gland secretes hormones throughout the body. Lymphoma, a cancer of a type of white blood cells called lymphocytes, can be categorized as either Hodgkin lymphoma or non-Hodgkin lymphoma. A CD4:CD8 ratio of 4:1 or higher has a positive predictive value of 94%, but a sensitivity of only 59% in separating sarcoid from other interstitial lung diseases (22).
