Sarcoidosis Beyond the Lungs: Heart, Brain, and Skin

Last updated:

Extrapulmonary sarcoidosis occurs when the disease affects organs outside the lungs, most notably the heart, brain, and skin. Involvement of the heart or nervous system is serious and often requires aggressive treatment with immunosuppressants or a pacemaker.

Key Takeaways

  • • Cardiac sarcoidosis can be 'silent,' making regular screening with an EKG essential to prevent dangerous heart rhythms.
  • • Neurosarcoidosis can mimic conditions like multiple sclerosis and may cause severe headaches, facial drooping, or weakness.
  • • Skin involvement is common and can appear as purple-blue plaques, raised scars and tattoos, or painful bumps on the shins.
  • • Organ involvement beyond the lungs usually requires a shift to more aggressive treatments, such as immunosuppressants or implanted cardiac devices.

While sarcoidosis most often affects the lungs, it is a systemic disease that can appear in almost any part of the body [1][2]. When it moves beyond the lungs, it is called extrapulmonary sarcoidosis [3]. Because these forms can be more hidden and carry different risks, monitoring for “red flag” symptoms in the heart, nervous system, and skin is a vital part of your long-term care [4].

Cardiac Sarcoidosis (The Heart)

Cardiac sarcoidosis (CS) is one of the most serious forms of the disease [5]. It is often underdiagnosed because it can be “silent,” showing no symptoms until a major event occurs [6][7].

  • The Risks: The granulomas can interfere with the heart’s electrical system, leading to dangerous heart rhythms (arrhythmias), heart block, or even sudden cardiac death [8][9][10].
  • Diagnosis: Because CS can be “silent,” an annual EKG (and sometimes an echocardiogram) is a mandatory, essential first-line screening tool for all patients [11]. If these initial tests show “red flags” or if you have symptoms, doctors will then use advanced tests like Cardiac MRI (CMR) to look for scarring, and FDG-PET scans to find active inflammation [12][13].
  • Red Flags: Seek immediate medical attention for fainting (syncope), unexplained dizzy spells, or a racing or irregular heartbeat [14][15].

Neurosarcoidosis (The Nervous System)

When sarcoidosis affects the brain, spinal cord, or nerves, it is called neurosarcoidosis (NS) [16]. It is known as a “great mimicker” because it can look like multiple sclerosis or a stroke [17][16].

  • Symptoms: Common signs include cranial nerve palsies (such as one side of the face drooping), severe headaches, seizures, or weakness and numbness in the limbs [18][16][19].
  • Investigation: An MRI of the brain or spine with contrast is the gold standard for spotting these areas of inflammation [20][21]. Doctors may also perform a lumbar puncture (spinal tap) to check for immune markers in the spinal fluid [22][23].

Cutaneous Sarcoidosis (The Skin)

The skin is the second most common place sarcoidosis appears [24]. Skin lesions are often the “window” that leads to a diagnosis of the whole body [25].

  • Lupus Pernio: Thickened, purple-blue or red skin plaques, usually on the nose, cheeks, or ears. This form is often linked to more chronic lung disease [26][27].
  • Scar and Tattoo Sarcoidosis: A unique sign where old surgical scars or tattoos suddenly become raised, itchy, or bumpy years after they were made [28][29][30].
  • Erythema Nodosum: Painful, red bumps on the shins. While uncomfortable, this is often a sign of a more acute form of sarcoidosis that has a better overall prognosis [31][24].

How Management Changes

Finding sarcoidosis in these areas often shifts the treatment plan from “watchful waiting” to active management [32].

  1. More Aggressive Treatment: Involvement of the heart or brain almost always requires starting high-dose corticosteroids or “steroid-sparing” immunosuppressants like methotrexate or infliximab to prevent permanent damage [33][34][35].
  2. Protective Devices: If the heart’s electrical system is damaged, you may need a pacemaker or an Implantable Cardioverter-Defibrillator (ICD) to prevent sudden cardiac arrest [36][14][37].
  3. Specialist Teams: You will likely need a multidisciplinary team, including a cardiologist or neurologist who specializes in sarcoidosis, to ensure all affected systems are being monitored [38][39].
Organ System Key Signs to Watch Essential Tests
Heart Fainting, palpitations, lightheadedness [14] EKG, Cardiac MRI, FDG-PET, BNP [13][40]
Brain/Nerves Face droop, severe headaches, weakness [18] Brain/Spine MRI, Lumbar Puncture [20][22]
Skin Raised scars, purple nose plaques, shin bumps [28] Skin Biopsy [41]

Frequently Asked Questions

How do I know if sarcoidosis is affecting my heart?
Cardiac sarcoidosis can often be silent, showing no symptoms until a major event occurs. An annual EKG is an essential screening tool, but you should seek immediate medical attention if you experience fainting, unexplained dizzy spells, or a racing heartbeat.
What are the symptoms of neurosarcoidosis?
When sarcoidosis affects the nervous system, it can cause severe headaches, facial drooping, seizures, or weakness and numbness in the limbs. An MRI of the brain or spine is typically used to investigate these symptoms.
Can sarcoidosis affect old scars or tattoos?
Yes, a unique sign of the disease is scar and tattoo sarcoidosis. You may notice that old surgical scars or tattoos suddenly become raised, itchy, or bumpy years after they were made.
Does treatment change if sarcoidosis is found in my heart or brain?
Finding sarcoidosis in the heart or nervous system usually shifts your care plan from watchful waiting to active management. Your doctor will likely prescribe high-dose corticosteroids or immunosuppressants to prevent permanent damage.

Questions for Your Doctor

  • • Given that I have sarcoidosis, should I have a baseline Cardiac MRI or FDG-PET scan to screen for 'silent' heart involvement?
  • • Are the headaches or dizzy spells I've been having related to neurosarcoidosis, and should we consider a brain MRI or lumbar puncture?
  • • If my skin biopsy shows sarcoidosis, does that automatically mean it is in my lungs or other organs as well?
  • • If we find cardiac involvement, will I need an Implantable Cardioverter-Defibrillator (ICD) to protect against sudden heart rhythm issues?
  • • How does finding sarcoidosis in my skin or nervous system change our 'watch and wait' strategy? Will I need more aggressive treatment?

Questions for You

  • • Have you ever felt your heart 'skip a beat' or race for no reason, or have you ever fainted or felt like you were about to faint?
  • • Have you noticed any new weakness in your face, difficulty swallowing, or changes in your balance or coordination?
  • • Do you have any old tattoos or surgical scars that have recently become raised, itchy, or painful?
  • • Are you experiencing any 'invisible' symptoms like sudden mood changes, memory problems, or severe, persistent headaches?
