Sarcoidosis

Sarcoidosis, also called sarcoid, is a disease involving abnormal collections of inflammatory cells that form lumps known as granulomas. The disease usually begins in the lungs, skin, or lymph nodes. Less commonly affected are the eyes, liver, heart, and brain. Any organ, however, can be affected. The signs and symptoms depends on the organ involved. Often there are no or only mild symptoms. When it affects the lungs there may be wheezing, cough, shortness of breath, or chest pain. Some may have Lofgren's syndrome in which there is fever, large lymph nodes, arthritis, and a rash known as erythema nodosum.
