Sarcoidosis Care in Collegeville, PA
Sarcoidosis is an inflammatory disease that forms clusters of immune cells in the body, most often in the lungs and lymph nodes.
What is sarcoidosis?
Sarcoidosis is an inflammatory disease in which small clusters of immune cells, called granulomas, form in organs. The lungs and lymph nodes are most often affected, but it can also involve the skin, eyes, joints, liver, heart, and nerves. The cause is unknown, and in many people the disease improves on its own.
Common symptoms
- A persistent dry cough, shortness of breath, or chest discomfort
- Fatigue, fever, or unintended weight loss
- Swollen lymph nodes
- Painful red bumps on the shins with ankle swelling and pain
- Eye redness, pain, or blurred vision
- Skin lesions and joint pain
How sarcoidosis is diagnosed
Diagnosis involves your history and examination, a chest X-ray or CT scan, blood tests, and often a tissue biopsy to confirm granulomas and exclude other causes, such as infection. We also check which organs are involved, including the lungs, eyes, and heart, and coordinate with other specialists when needed.
Treatment
Not everyone needs medication, and some people are monitored closely over time. When treatment is needed, it often starts with corticosteroids, and other immune-modulating medications may be used to reduce steroid exposure. Regular follow-up tracks organ involvement and response to treatment.

Frequently asked questions about sarcoidosis
Does sarcoidosis go away on its own?
Often it improves without treatment, especially in some forms, but it can come back or persist. Monitoring is important, since it can affect several organs.
Is sarcoidosis contagious?
No. Sarcoidosis cannot be passed from one person to another.
Why would a rheumatologist treat sarcoidosis?
Sarcoidosis can involve the joints and many organ systems and often needs immune-modulating treatment, so rheumatologists commonly help diagnose and manage it, working with lung, eye, and other specialists.
