Sarcoidosis is an inflammatory disease in which small clusters of immune cells, called granulomas, form in various organs, most commonly the lungs and lymph nodes. This causes organ inflammation and can affect normal function. The exact cause is unknown but is believed to involve an abnormal immune response to environmental or infectious triggers. Symptoms vary widely, and early diagnosis with imaging, pulmonary function tests, and sometimes biopsy is essential. Treatment focuses on controlling inflammation and managing symptoms to prevent long-term organ damage.
