Sarcoidosis (sahr-koi-DOH-sis) is a disease in which small clumps of cells (granulomas)
form in certain organs of the body.
More to Know
Doctors believe the cause of sarcoidosis involves an immune
system response to something in the environment. When the immune system senses
a threat, it produces cells that clump together to form granulomas, which are a bit
like tiny tumors. Granulomas can build up in an organ and affect the way that organ
functions. Sarcoidosis can be found in just about any part of the body, but it often
affects the lungs, skin, eyes, nervous system, heart, lymph
nodes, and spleen.
Sometimes sarcoidosis doesn't cause any symptoms and is only discovered on a chest X-ray for another
condition. In other cases, sarcoidosis can cause chest pain, breathing difficulties,
dry cough, fatigue, fever, or skin rash. Severe sarcoidosis that goes untreated can
eventually lead to lung damage, organ failure, and other complications.
Keep in Mind
Sarcoidosis is rare in young children. Many people with sarcoidosis need no treatment
and improve on their own. Treatment, such as with steroids, is usually only necessary
if the disease appears to be affecting the way organs function. People with severe
sarcoidosis may need treatment for life.
