What is Sarcoidosis?

Sarcoidosis is an inflammatory disease that is defined by clumps of inflammatory cells called granulomas. The immune system is overworking and forms these granulomas in different organs of the body, primarily the lungs and lymph nodes in the chest. Sometimes the disease improves without treatment and sometimes treatment is started to help manage symptoms.

Acknowledgement of Sarcoidosis has not been added yet.

Sarcoidosis is more prevalent in African Americans than Caucasians, and often African Americans experience more severe symptoms. Affected individuals are usually over the age of 20. Women are more likely to develop sarcoidosis versus men.

The highest prevalence is seen in Northern European countries, 5 to 40 cases per 100,000 people. In Japan, it is 1 to 2 cases per 100,000 people. In the United States, the incidence among African Americans is approximately 35.5 cases per 100,000 and approximately 10.9 per 100,000 for Caucasians.

Synonyms for Sarcoidosis has not been added yet.

The underlying cause of sarcoidosis is unknown. Inherited genes and environmental triggers can cause the immune system to have an inflammatory response. There are no specific gene mutations that can cause sarcoidosis. It can sometimes run in the family; there is a genetic tendency to develop the disease. Environmental triggers such as, bacteria, viruses, or chemicals can cause the immune system to activate, leading to inflammation, and leading to granuloma formation in the organs.

There are some risk factors that can increase a person’s chance of developing sarcoidosis. Risk factors include age, family history or genetics, environment or occupation, race or ethnicity, gender, and other medical conditions.

Sarcoidosis often occurs in women, ages 20 to 40, in certain ethnic groups. Sarcoidosis is highest in African Americans and Northern Europeans, specifically Scandinavians.

Many affected individuals with sarcoidosis are asymptomatic; meaning they have no signs or symptoms and feel fine. Some affected individuals may have flu-like symptoms, such as a fever, night sweats, wheezing, cough, congestion, and fatigue. Other affected individuals with experience symptoms depending on the affected organ that the granulomas are clustered at. If inflammation continues on an area or an organ, many individuals develop permanent scarring. Permanent scarring can be life threatening if it affects the heart or the lungs.

Sarcoidosis can affect any organ, but it primarily affects the lungs. The most common symptom is flu-like symptoms. Other symptoms include, depression, weight loss, chest pain, skin rashes or bumps on the skin, joint pain and stiffness, eye irritation and dryness, increased heart rate or palpitations, lightheadedness, kidney stones, increased calcium in the blood, and abnormal liver function.

Other symptoms related to specific organs are abdominal pain, enlarged spleen, anemia, muscle weakness, enlarged liver accompanied by nausea/vomiting and jaundice, issues with the nervous system, skin changes, swollen salivary glands, and swollen or tender lymph nodes.

There are many complications of sarcoidosis, especially if it is left untreated or treatment does not work. The inflammation can continue and cause scarring. Life threatening scarring on organs can cause blindness, blood and bone marrow problems, endocrine system issues (high calcium in blood, diabetes insipidus, and amenorrhea), heart complications, kidney dysfunction, cirrhosis or liver disease, lung diseases, or head complications, such as brain tumors, meningitis, and psychiatric problems.

In diagnosing an individual with sarcoidosis, the physician has to rule out any other causes or diseases. To rule out other diseases, a blood tests, a bronchoscopy, environmental questionnaire, and a urinalysis are performed. The diagnose sarcoidosis, the physician observes symptoms present and performs a physical exam, imaging tests, and/or a biopsy of an affected organ.

There are five different stages of sarcoidosis. These stages indicate where the granulomas are located. Stage 0 to III can range from mild to severe. Stage IV is most severe.

  • Stage 0 is no pulmonary sarcoidosis; there is no sign of granulomas in the lungs or lymph nodes.
  • Stage I is lymphadenopathy; there are granulomas in the lymph nodes only.
  • Stage II is lymphadenopathy and pulmonary infiltrates; there are granulomas in both the lymph nodes and the lungs.
  • Stage III is pulmonary infiltrates; there are granulomas in the lungs only.
  • Stage IV is pulmonary fibrosis; there is permanent scarring of the lung tissue and is life-threatening.

There are many common tests that is used to diagnose sarcoidosis.

  • Chest X-ray – an x-ray of the lungs can show sarcoidosis and/or scarring of the lung tissues
  • CT scans – CT scans the cross-section of the body and requires contrast dies. It can show images of the lungs and the lymph nodes
  • Pulmonary function tests – PFTs measure the amount and speed of air that the person blows out. It gives data on how well the lungs are working.
  • Lung biopsy – if pulmonary fibrosis is suspected, the physician can order a lung biopsy to get a small sample of the lung tissue. The tissue is analyzed in a laboratory for signs of sarcoidosis and scarring.
  • Echocardiogram – EKG is an ultrasound of the heart. It checks how the heart is working and pumping blood.
  • Eye exam – examines the eyes to see if sarcoidosis has affected the eyes
  • Blood test – these laboratory tests check to see if there are signs of inflammation, high calcium in the blood, kidney function, and liver function

Not all affected individuals that are diagnosed with sarcoidosis need treatment. For others, the condition can go away on its own as well. Sarcoidosis cannot be completely cured or eliminated, but many affected individuals can achieve remission. Remission is a state of the condition where it is not causing problems or manifesting symptoms. Some selected individuals may not respond well to treatment or not at all.  

All treatment depends on the affected individuals’ symptoms, which organs are affected, and which organ are working well.  Since sarcoidosis is a condition where the immune system is overactive and forming granulomas, medications used to treat sarcoidosis turns down or slows down the immune system’s activity.

The most common type of medicine used is steroids. Steroids turn off the immune system, reduces inflammation, controls cough and shortness of breath, alleviates skin rashes, and helps with joint pain. Prednisone is the most common steroid used. Prednisone can be taken as a pill, injected, inhaled, or as an eyedrop. There can be long-term side effects when using steroids long-term. Some primary side effects of steroids are weight gain, insomnia, bone loss, vision changes, high blood pressure, and high blood sugar/diabetes. Once the affected individual starts a steroid, the steroid cannot be suddenly stopped. The steroid must be slowly tapered off over a period of time.

Another type of medicine used is called disease-modifying antirheumatic drugs (DMARDs). DMARDs treat and slow down an overactive immune system. Some examples of DMARDs are methotrexate, azathioprine, and leflunomide. Side effects include liver damage or liver dysfunction.

Antimalarial are originally used to treat malaria. Hydroxychloroqine and chloroquine has shown to affect the immune system’s function. It is the most effective for individuals with sarcoidosis that have skin symptoms and/or high levels of calcium in the blood. Side effects include stomachs irritation and eye problems.

Other medications that can treat sarcoidosis include, anti-TNF monoclonal antibodies, colchicine, corticotropin, and pentoxifylline. All medications have many side effects. They all require close monitoring and adjusting by a specialist or healthcare provider.

Affected individuals with severe or advanced lung sarcoidosis may need oxygen therapy or lung transplant.



In over half of the affected patient population, granulomas disappear over a period of two to five years. If the patient achieves remission, it can be life-long remission or temporary remission. If the patient has a severe and aggressive case, then on-going treatment and transplantation may be necessary.

It is important to follow up with the specialist and healthcare providers. Make appointments for routine checkups, diagnostic exams, and blood test. Adopt a healthier lifestyle by being active, having a healthy weight, eating heart-healthy, managing stress, and quitting smoking.

Has anyone else experienced extremely itchy skin? This began about 3 years ago, shortly before I was diagnosed with sarcoid. My dermatologist says it's due to the sarcoid but I don't seem to be able to find it as one of the many symptoms.

I noticed that the discussions seem out of date too!  I've been looking for sites and did find one - inspire - search "stop sarcoidosis". It s a good source of information about sarc.   I like reading all the posts, but they can be kinda scary. I don't have all the symptons mentioned from different users and I'm not sure what to expect.  I

I was diagonosed this year (after 2 yrs of tests).  I have it in my lungs and in my right eye.  The eye is my main problem now.  It is so full of debres and floaters that I cannot see out of it.  I have been on predinose for 1 1/2 years, but I have to take 40 mg to even help my eye clear up which is too much to take on a long term basis.  Have had 2 surgeries(vitrectomy) on it - It clears up for a month, then back to fogged in.

I need to get off the predisone and am waiting on my doctor to get the insurance to approve the medicine he wants me to start taking, as the predisone causes too much side effects.  I now have predisone induced glaucoma in my right eye, The predisone causes cateracts and makes them worse and you can't do surgery on the cateracts until the inflammation is gone.  ARRGGHGHHH

I have dermatological sarcoids only.  Hi there, I have NOT found topical steroids to be any use.  They seem to make my skin worse.I have had this for 8 years or more and it's getting worse.  I'm willing to try scorched earth methods.  I suspect there is something more than just an autoimmune thing going on, but the biopsy says "sarcoidosis".

I have been on prednisone since prior to my sarcoid diagnosis. I know that all literature states that prednisone is one means of meds that can have a calming effect with sarcoid. I only notice flare ups evrey couple of months. Other than that, I suffer with chronic pain (everything from the neck down), swollen legs and ankles, chronic joint pain. Most of my flare ups are severe when the prednisone dosage drops below either 10 or 15mg. So I unfortunately have been on this medicine for years. I have lost 3/4 hearing in the right ear and haven't gotten it back and lost vision in both eyes. I have been on mexatrexate as well for a couple of yrs. I was previously on embrel but have recently been taken off. I recently started a medicine called Gabapentine.

Flare ups don’t seem to be avoidable. I believe that working out (with controlled exercises) 4 times a week for 30 minutes and remaining mentally active through business- oriented volunteer work for the remainder of weekday time keeps me well (as well as can be when you have sarcoid). To minimize the flare up - for me, I have an underlying "true" infection and this must be treated aggressively with IV anti-biotics (even if the it's location is unknown - use a broad anti-b) and then the sarcoid flare that accompanies this action seems to be easier to manage and seems to get minimized.

My husband has sarcoidosis.  He has a history of German ancestry.  He ws diagnosed with sarcoids in lungs in 1993 with no symptoms.  After being in New Orleans during Katrina he had a blood clot then SVC syndrome with no history of lines.  3 years ago his H&H went down and he had ascites, and his albumin went to almost nothing. He also had severe cold spells, loss of energy and appetitie, and weight loss.  It resolved on its own 6 months later.  He now has some symptoms again. Sometimes the doctors just want to believe it is not sarcoids but always is.

I don't you asking my age, I am 46, but ha ve spent the last 15 years NOT takingu care of me. I also have COPD and Bronchitis ... I get lung infections very easily. and now I am on oxygen 24/7 thats a lot to get used to. I live in New York, about an hour from Buffalo...its cold and snowy here today. You have a Blessed Day as well Talk soon Amy

Good Morning Amy, I am glad you are in a good place right now, and can concentrate on your health. I am glad you have reached out, I do want you to join the sarcoidosis community as well. Also, have you heard of FSR(Foundation for Sarcoidosis Research) they are located in Chicago,IL. 866.368-KISS I suggest FSR to you, so you have others to connect to that might also have to consider different avenues. Do you mind me asking how old you are? Do you have an overlap of dx or is Sarcoidosis your ddx(diagnosis)? Have a blessed day, Lisa

Hi Lisa, I was diagnosed 15 years ago, but because of so many negative things in my life, (very LONG stories !) I never concentrated on taking care of myself, and have just really admitted how sick I really am. I am in a good situation now though, able to make decisions that are good for me, and I am not being pressured or made to feel bad because I am sick. I have a terrible time with infection and just got out of the hospital on the 5th after a weeks stay, and have been taken out of wor, and put on oxygen ... Dr.'s want me to consider some different avenues, including revisting the option of a double lung transplant ... that is why I am doing so much research and weight my pro's and cons ... and I need others to talk too. So glad I found you. I hope we can become help for each other. I will share more soon. I know my faith is strong and God has a plan and will see me through this,, I know there is an answer, and God has a plan. I am looking forward to sharing. Thanks Lisa Amy

They should have been able to tell you from the surgery if it was Sarcoid if the nodules were non-caseating granulomas or what. That is usually how it is definately dx'd. There can be other symptoms such as weight loss, hair loss, night sweats along with a mirad of many others.

I am guessing that I have this condition, after seeing many specialists in South Africa they can find no positive reason for my persistant agressive coughing. Basically every time I inhale quickly as when laughing or shouting, when bending forward or sitting in a low seat, any exercise like walking up stairs. I used to be very active & sporty but now am always tired and consequently have become overweight. I had scans where they found a number of small nodules in my lungs when I had an operation to have one removed it was diagnosed as non malignant but no other comment. I have a mild reflux condition and slightly abnormal gastric action where food passes through my asophegous into the duodenum, which can cause coughing but not to the extent that I suffer.

The symptoms and signs that patients have with Sarcoidosis and Lyme are rarely recognised by most GP's and specialists, as constituting a discrete systemic illness.



Many symptoms associated with these systemic diseases are not seen as a whole constellation of problems resulting from the diseases themselves, but as separate and unrelated conditions which can include but not limited to: fibromyalgia, bursitis, arthritis, facial palsy (drooping and/or paralysis of the muscles on one side of your face), headaches, tinnitus, restless leg syndrome, uveitis, eye pain, blurry or double vision, blindness, weakness, numbness, tingling and/or pain in the face, arm and/or leg paralysis, muscle fatigue, seizures, behavior and mood changes, irritability, memory loss and hallucinations. Neurosarcoidosis can even include: nerve inflammation and damage, peripheral neuropathy, masses of granulomas in the meninges (or more rarely in the brain) that can lead to meningitis, hydrocephalus and neuroendocrine disorders and even coma etc just to name a few.

The Dorothy P. & Richard P. Simmons Center for Interstitial Lung Diseases

Founded in 2001 thanks to the generosity of the Simmons family, the Dorothy P. & Richard P. Simmons Center for Interstitial Lung Disease is designed to provide patient-friendly advice and support for people with Idiopathic Pulmonary Fibrosis (IPF).

Foundation for Sarcoidosis Research

The Foundation for Sarcoidosis Research (FSR) is the nation’s leading nonprofit organization dedicated to improving care for sarcoidosis patients and to finding a cure for this disease.

The Sarcoidosis Center is a non-profit corporation designed to provide information for patients and physicians regarding sarcoidosis.


Clinical Trials

Cords registry

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access.

Enrolling is easy.

  1. Complete the screening form.
  2. Review the informed consent.
  3. Answer the permission and data sharing questions.

After these steps, the enrollment process is complete. All other questions are voluntary. However, these questions are important to patients and their families to create awareness as well as to researchers to study rare diseases. This is why we ask our participants to update their information annually or anytime changes to their information occur.

Researchers can contact CoRDS to determine if the registry contains participants with the rare disease they are researching. If the researcher determines there is a sufficient number of participants or data on the rare disease of interest within the registry, the researcher can apply for access. Upon approval from the CoRDS Scientific Advisory Board, CoRDS staff will reach out to participants on behalf of the researcher. It is then up to the participant to determine if they would like to join the study.
