Sarcoidosis

Sarcoidosis is a disease characterized by inflammation and abnormal collections of immune cells called granulomas, which can affect various organs including the lungs, lymph nodes, skin, and eyes, often resulting in symptoms like wheezing, coughing, shortness of breath, or more generalized symptoms like fever and arthritis. Although it commonly begins in the lungs or lymph nodes, any organ can be affected, sometimes with only mild or no symptoms.
