Sarcoidosis is a mystery disease.
There's probably more than one cause. It is characterized by inflamed, microscopic growths called granulomas, most often found in the lungs. Sarcoidosis can cause redness in the eyes, shortness of breath, bumps on the skin, fatigue, fever and general pain caused by exposure to light. Oral corticosteroids are used to treat sarcoidosis. About 3 percent of African-American women risk getting the disease sometime during their adult lives.
