Head and Neck Sarcoidosis: Symptoms, Diagnosis, and Treatment Options

Introduction

Sarcoidosis is an inflammatory disease that can affect various organs, including the head and neck region. It occurs when small clusters of inflammatory cells, called granulomas, form in affected tissues. While sarcoidosis can impact any part of the body, involvement in the head and neck area can lead to specific symptoms and complications. This article provides a comprehensive overview of sarcoidosis affecting the head and neck, covering risk factors, symptoms, diagnostic tests, treatments, and self-care strategies. Understanding the condition and its management empowers patients to take an active role in their care and collaborate closely with healthcare providers to manage symptoms effectively.

Definition of Head and Neck Sarcoidosis

Head and neck sarcoidosis is characterized by the formation of granulomas in the tissues of the head and neck. Risk factors include lifestyle, medical history, and genetics. Symptoms can range from swelling to breathing difficulties, and diagnostic tests such as imaging and biopsies are used to confirm the condition. Treatments typically involve medications and procedures, while home care strategies can help alleviate symptoms.

Description of Sarcoidosis in the Head and Neck

Sarcoidosis in the head and neck is a specific manifestation of a systemic inflammatory disease, often involving the lymph nodes, salivary glands, skin, and sometimes the upper respiratory tract. The exact cause remains unknown, but it is believed to result from an abnormal immune response triggered by infection or environmental exposure. In the head and neck, sarcoidosis may present with swollen lymph nodes, facial skin lesions, or inflamed salivary glands, which can lead to dry mouth or difficulty swallowing.

The progression of sarcoidosis varies. In some cases, it resolves without treatment, while in others, it becomes chronic and requires ongoing management. Complications can include tissue damage, scarring, or, in rare instances, involvement of the eyes, nerves, or other critical structures in the head and neck.

Statistics show that sarcoidosis affects 10 to 20 people per 100,000 in the U.S., with a higher prevalence among African Americans and Northern Europeans. While sarcoidosis commonly affects the lungs, head and neck involvement occurs in about 10-15% of cases. Early diagnosis and treatment are essential for preventing complications and improving quality of life.

Risk Factors for Developing Head and Neck Sarcoidosis

Lifestyle Risk Factors

Although the exact cause of sarcoidosis is unclear, certain lifestyle factors may increase the risk. Exposure to environmental elements like dust, chemicals, or mold may trigger the immune response that leads to sarcoidosis. Smoking, which impairs lung function, may also exacerbate inflammation, though its relationship with sarcoidosis is still under investigation. Occupations involving exposure to organic or inorganic dust, such as agriculture or construction, may also heighten the risk.

Medical Risk Factors

A history of certain infections, particularly respiratory ones, may increase susceptibility to sarcoidosis. Autoimmune diseases or chronic inflammatory conditions may also raise the risk, as sarcoidosis involves an abnormal immune response. Individuals with sarcoidosis in other parts of the body, such as the lungs or skin, are more likely to experience head and neck involvement.

Genetic and Age-Related Risk Factors

Genetics play a significant role in sarcoidosis development. Those with a family history of the condition are more likely to develop it, suggesting a genetic predisposition to abnormal immune responses. Sarcoidosis is more common in African Americans and typically affects adults between 20 and 40, though it can occur at any age.

Clinical Manifestations of Head and Neck Sarcoidosis

Facial Swelling

Facial swelling occurs in about 25% of patients with head and neck sarcoidosis. Granulomas in the soft tissues of the face can block lymphatic drainage, leading to fluid accumulation and swelling. This symptom is more common in the early stages and may be accompanied by lymphadenopathy (swollen lymph nodes). Treatment focuses on reducing inflammation and managing sarcoidosis.

Lymphadenopathy

Lymphadenopathy, or swollen lymph nodes, affects 30-40% of patients with head and neck sarcoidosis. Granulomas in the lymph nodes cause them to enlarge, particularly in the neck, under the jaw, and behind the ears. Swollen lymph nodes may be tender or painless and are often one of the first signs of sarcoidosis. If significant, swelling can cause discomfort or pressure on nearby structures.

Nasal Obstruction

Nasal obstruction affects 10-20% of patients with head and neck sarcoidosis. Granulomas in the nasal passages cause inflammation and swelling, leading to a blocked or congested feeling. This symptom is more common in advanced disease. Treatment typically involves corticosteroids to reduce inflammation and improve airflow.

Sinusitis

Sinusitis affects 15-25% of patients with head and neck sarcoidosis. Granulomas can block sinus drainage pathways, leading to inflammation and infection. Symptoms include facial pain, pressure, nasal discharge, and headaches. Chronic sinusitis may develop if untreated, requiring a combination of anti-inflammatory medications and antibiotics.

Eye Inflammation

Eye inflammation, or uveitis, occurs in 20-30% of sarcoidosis patients, including those with head and neck involvement. Inflammation can affect various parts of the eye, causing redness, pain, light sensitivity, and blurred vision. If untreated, complications like glaucoma or cataracts may result in permanent vision loss. Early treatment with corticosteroids or immunosuppressive medications is crucial to preserving vision.

Skin Lesions

Skin lesions affect about 25% of sarcoidosis patients. These lesions appear as raised, red, or purple patches, often on the face, neck, or scalp. While generally not painful, they can be cosmetically concerning. In some cases, lesions resolve on their own, but corticosteroids may be necessary to reduce inflammation and improve appearance.

Dry Mouth

Dry mouth, or xerostomia, affects 10-15% of patients with head and neck sarcoidosis. Granulomas in the salivary glands reduce saliva production, leading to a dry, sticky feeling, difficulty swallowing, and an increased risk of dental problems. Treatment may involve medications to stimulate saliva production or artificial saliva products.

Hoarseness

Hoarseness affects 5-10% of patients with head and neck sarcoidosis. Granulomas on or around the vocal cords cause inflammation and swelling, leading to changes in voice pitch or quality. In severe cases, patients may lose their voice. Treatment typically involves corticosteroids to reduce inflammation and improve vocal cord function.

Hearing Loss

Hearing loss affects 5-10% of patients with head and neck sarcoidosis. Granulomas in the middle or inner ear can cause conductive or sensorineural hearing loss. Symptoms include muffled hearing, tinnitus (ringing in the ears), or a feeling of fullness. Early intervention with corticosteroids or immunosuppressive therapies may help preserve hearing.

Fatigue

Fatigue affects 60-70% of sarcoidosis patients, including those with head and neck involvement. The cause of fatigue is not fully understood but is thought to be related to chronic inflammation and immune response. Fatigue can be debilitating, affecting daily activities. Managing fatigue involves treating the underlying sarcoidosis, improving sleep, and addressing contributing factors like depression or anemia.

Diagnostic Evaluation of Head and Neck Sarcoidosis

Diagnosing head and neck sarcoidosis involves clinical evaluation, imaging studies, and laboratory tests. A healthcare provider will take a detailed medical history and perform a physical examination, looking for signs like swollen lymph nodes, skin lesions, or nasal obstruction. Based on the findings, additional tests may be ordered to confirm the diagnosis and rule out other conditions. These tests detect granulomas, assess organ involvement, and evaluate disease severity.

Chest X-ray

A chest X-ray is often the first imaging study ordered when sarcoidosis is suspected. It uses a small amount of radiation to create images of the chest, including the lungs and heart. This test is useful for detecting granulomas or enlarged lymph nodes in the lungs, which are commonly affected in sarcoidosis. Lung involvement is seen in up to 90% of sarcoidosis cases, making a chest X-ray an important diagnostic tool.

Results indicating sarcoidosis on a chest X-ray include bilateral hilar lymphadenopathy (enlarged lymph nodes on both sides of the chest) and pulmonary infiltrates (areas of lung inflammation). If these findings are present, sarcoidosis is strongly suggested, even if symptoms are primarily in the head and neck. If the chest X-ray is normal but symptoms persist, further tests like a CT scan or biopsy may be needed.

CT Scan

A CT (computed tomography) scan provides more detailed images than a chest X-ray and is often used to assess sarcoidosis in the lungs, sinuses, or other areas. The patient lies on a table that moves through a large, ring-shaped machine, which takes multiple X-ray images from different angles. These images are combined to create cross-sectional views of the body. A CT scan helps identify granulomas, lymph node enlargement, and other abnormalities not visible on a standard X-ray.

In head and neck sarcoidosis, a CT scan of the sinuses or neck may reveal granulomas in the nasal passages, sinuses, or salivary glands. Results indicating sarcoidosis include soft tissue masses, mucosal thickening, or bone erosion caused by granulomas. If the CT scan is negative but symptoms persist, further testing, such as a biopsy, may be needed.

Health Conditions with Similar Symptoms to Sarcoidosis (Head and Neck)

Tuberculosis

Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis. While it primarily affects the lungs, it can spread to other areas such as the lymph nodes, bones, and skin. TB is highly contagious, spreading through the air when an infected person coughs or sneezes. Common symptoms include a persistent cough, fever, night sweats, and weight loss.

How to Know if You Might Have Tuberculosis vs. Sarcoidosis (Head and Neck)

Both tuberculosis and sarcoidosis can cause enlarged lymph nodes, fatigue, and weight loss. However, TB often presents with more severe respiratory symptoms, such as a chronic cough producing blood or sputum, which is uncommon in sarcoidosis. Night sweats and fever are also more pronounced in TB. TB is caused by a bacterial infection, while sarcoidosis is an inflammatory disease of unknown origin.

To differentiate, a healthcare provider may order a tuberculin skin test (TST) or an interferon-gamma release assay (IGRA) to check for TB infection. A positive result suggests TB. Chest X-rays or CT scans may show lung abnormalities in both conditions, but TB often presents with cavitary lesions (hollow spaces in the lungs), which are not typical in sarcoidosis. A biopsy can further distinguish between the two, as TB granulomas show necrosis (tissue death), while sarcoidosis granulomas are non-necrotizing.

Lymphoma

Lymphoma is a cancer of the lymphatic system, affecting lymphocytes (a type of white blood cell). There are two main types: Hodgkin lymphoma and non-Hodgkin lymphoma. Symptoms include swollen lymph nodes, fever, night sweats, unexplained weight loss, and fatigue. Lymphoma can affect the neck, chest, and abdomen.

How to Know if You Might Have Lymphoma vs. Sarcoidosis (Head and Neck)

Both lymphoma and sarcoidosis can cause swollen lymph nodes, fatigue, and weight loss. However, lymphoma is more likely to cause persistent fevers and night sweats, which are less common in sarcoidosis. Lymphoma may also cause itching, especially after alcohol consumption, a symptom not seen in sarcoidosis.

A biopsy is often needed to differentiate between the two. Lymphoma biopsies reveal abnormal cancerous cells, while sarcoidosis shows non-cancerous granulomas. Blood tests may show elevated lactate dehydrogenase (LDH) levels in lymphoma, which are not typical in sarcoidosis. PET scans can also reveal areas of high metabolic activity, more common in lymphoma.

Granulomatosis with Polyangiitis (GPA)

Granulomatosis with polyangiitis (GPA), formerly known as Wegener’s granulomatosis, is a rare autoimmune disease that causes inflammation of blood vessels (vasculitis). This inflammation can restrict blood flow to organs like the sinuses, lungs, and kidneys. Symptoms include sinus pain, nosebleeds, cough, shortness of breath, and joint pain.

How to Know if You Might Have Granulomatosis with Polyangiitis vs. Sarcoidosis (Head and Neck)

Both GPA and sarcoidosis can cause respiratory symptoms like sinus pain and cough, along with fatigue. However, GPA is more likely to cause nosebleeds, nasal crusting, and kidney problems, which are uncommon in sarcoidosis. GPA may also cause joint pain and skin rashes, which are less frequent in sarcoidosis.

Blood tests for antineutrophil cytoplasmic antibodies (ANCA) can help diagnose GPA, as a positive result is highly suggestive. A biopsy can also help; GPA shows granulomas and vasculitis, while sarcoidosis typically shows granulomas without vasculitis. Chest CT scans may show nodules in both conditions, but GPA is more likely to cause cavitary lesions.

Sjögren’s Syndrome

Sjögren’s syndrome is an autoimmune disease primarily affecting moisture-producing glands, such as the salivary and tear glands, leading to dry mouth and eyes. Other symptoms include joint pain, fatigue, and swollen salivary glands. It can also affect organs like the kidneys, lungs, and nervous system.

How to Know if You Might Have Sjögren’s Syndrome vs. Sarcoidosis (Head and Neck)

Both Sjögren’s syndrome and sarcoidosis can cause fatigue, joint pain, and swollen salivary glands. However, Sjögren’s is more likely to cause dry mouth and eyes, which are not typical in sarcoidosis. Sjögren’s may also lead to dental problems due to reduced saliva, which does not occur in sarcoidosis.

Blood tests for anti-SSA and anti-SSB antibodies can help diagnose Sjögren’s syndrome. A lip biopsy may show salivary gland inflammation, characteristic of Sjögren’s but not sarcoidosis. In sarcoidosis, a biopsy typically shows granulomas rather than gland inflammation.

Sarcoid-like Reaction

A sarcoid-like reaction refers to granuloma formation in response to another condition, such as an infection or cancer. These granulomas resemble those seen in sarcoidosis but are triggered by a different cause. Sarcoid-like reactions can occur in the lymph nodes, lungs, or other organs.

How to Know if You Might Have a Sarcoid-like Reaction vs. Sarcoidosis (Head and Neck)

Both sarcoid-like reactions and sarcoidosis involve granuloma formation, causing similar symptoms like swollen lymph nodes and fatigue. However, sarcoid-like reactions are usually linked to an underlying condition, such as an infection or cancer, while sarcoidosis is a primary inflammatory disease of unknown cause.

A healthcare provider may look for signs of an underlying condition to differentiate between the two. For example, the presence of cancer or infection may suggest a sarcoid-like reaction. A biopsy may show granulomas in both conditions, but additional tests, such as blood cultures or imaging, may help identify an underlying cause in sarcoid-like reactions.

Histoplasmosis

Histoplasmosis is a fungal infection caused by inhaling spores of Histoplasma capsulatum, commonly found in soil and bird droppings. It primarily affects the lungs but can spread to other parts of the body, especially in people with weakened immune systems. Symptoms include cough, fever, chest pain, and fatigue.

How to Know if You Might Have Histoplasmosis vs. Sarcoidosis (Head and Neck)

Both histoplasmosis and sarcoidosis can cause respiratory symptoms like cough, chest pain, and fatigue. However, histoplasmosis is more likely to cause fever and is often linked to environments where the fungus is present, such as caves or areas with bird droppings. Sarcoidosis is not caused by an infection and typically does not cause fever.

A healthcare provider may order a fungal culture or antigen test to check for Histoplasma fungus. A positive result suggests histoplasmosis. A biopsy may show granulomas in both conditions, but histoplasmosis will also show fungal organisms, while sarcoidosis will not.

Foreign Body Reaction

A foreign body reaction occurs when the body reacts to a foreign substance, such as a splinter or surgical implant. This reaction can cause inflammation and granuloma formation around the foreign material. Symptoms depend on the location of the foreign body and may include swelling, pain, or a lump.

How to Know if You Might Have a Foreign Body Reaction vs. Sarcoidosis (Head and Neck)

Both foreign body reactions and sarcoidosis can cause granulomas and localized swelling. However, a foreign body reaction is typically limited to the area where the foreign material is located, while sarcoidosis can affect multiple organs, including the lungs, lymph nodes, and skin. A foreign body reaction is also more likely to cause pain or discomfort at the site of the foreign material, which is uncommon in sarcoidosis.

Imaging tests, such as X-rays or ultrasounds, can help detect foreign objects. A biopsy may show granulomas in both conditions, but in a foreign body reaction, the granulomas will surround the foreign material. In sarcoidosis, no foreign material is present.

Treatment Options for Head and Neck Sarcoidosis

Medications

Corticosteroids

Corticosteroids are anti-inflammatory medications that reduce the immune system’s activity, which is often overactive in sarcoidosis. Prednisone is the most commonly prescribed corticosteroid.

Corticosteroids are typically the first-line treatment, especially when sarcoidosis affects vital organs like the lungs, eyes, or heart. For head and neck sarcoidosis, they are used when inflammation in the lymph nodes, salivary glands, or skin causes discomfort or dysfunction.

Patients may see symptom improvement within weeks to months, but long-term use may be necessary to keep the disease in remission. However, corticosteroids can have side effects, such as weight gain, high blood pressure, and osteoporosis, so doctors aim to use the lowest effective dose.

Methotrexate

Methotrexate is an immunosuppressive medication that reduces immune system activity, helping to control inflammation in sarcoidosis.

It is often used as a second-line treatment when corticosteroids are ineffective or cause significant side effects. Methotrexate can also be combined with corticosteroids to reduce the required steroid dose.

Patients may notice symptom improvement after several weeks of use. Methotrexate helps reduce inflammation and prevent further damage to affected tissues in the head and neck.

Azathioprine

Azathioprine is another immunosuppressive medication that helps control the immune system’s overactivity, reducing inflammation in sarcoidosis.

It is typically used in more advanced cases or when corticosteroids are insufficient. Azathioprine may also help reduce corticosteroid dosages and limit their side effects.

Patients can expect gradual symptom improvement over time, usually within a few weeks to months. It helps prevent further disease progression.

Hydroxychloroquine

Hydroxychloroquine, an anti-malarial drug with anti-inflammatory properties, is useful in treating sarcoidosis, particularly when it affects the skin or joints.

This medication is often used in milder cases, especially when sarcoidosis primarily affects the skin, such as facial lesions. It is also used when corticosteroids are not well-tolerated.

Patients may see improvement in skin symptoms after a few months of treatment. Hydroxychloroquine is generally well-tolerated, with fewer side effects compared to corticosteroids.

Infliximab

Infliximab is a biologic medication that blocks tumor necrosis factor (TNF), a protein that promotes inflammation. It is used to treat severe cases of sarcoidosis.

Infliximab is typically reserved for patients with severe or refractory sarcoidosis, particularly when the disease affects the lungs, eyes, or central nervous system. It may also be used in head and neck sarcoidosis when other treatments have failed.

Patients may experience significant symptom relief within weeks of starting infliximab, especially in cases of severe inflammation. However, it is usually used only after other treatments have been tried.

Adalimumab

Adalimumab is another TNF inhibitor, similar to infliximab, that helps reduce inflammation in sarcoidosis.

This medication is used in cases of severe sarcoidosis that do not respond to corticosteroids or other immunosuppressive drugs. It may be used in head and neck sarcoidosis if there is significant inflammation affecting the skin or lymph nodes.

Patients can expect to see improvement in symptoms within a few weeks to months. Adalimumab is typically used in combination with other treatments to manage severe disease.

Mycophenolate Mofetil

Mycophenolate mofetil is an immunosuppressive drug that helps control the immune system’s activity, reducing inflammation in sarcoidosis.

This medication is often used in more advanced cases of sarcoidosis, particularly when other treatments, such as corticosteroids, are not effective or cause significant side effects.

Patients may see improvement in symptoms over time, but it can take several weeks to months for the full effects to be noticeable. Mycophenolate mofetil can help prevent further disease progression.

Prednisone

Prednisone is a corticosteroid that reduces inflammation and suppresses the immune system.

It is often the first treatment prescribed for sarcoidosis, especially when the disease causes significant symptoms or affects vital organs. For head and neck sarcoidosis, prednisone is used to reduce swelling and inflammation in affected tissues.

Patients can expect to see symptom improvement within a few weeks of starting prednisone. However, long-term use may be necessary, and doctors will work to minimize the dose to reduce side effects.

Thalidomide

Thalidomide is an immunomodulatory drug that helps reduce inflammation and control the immune system’s activity.

It is typically used in severe or refractory cases of sarcoidosis, particularly when other treatments have failed. Thalidomide may be used in head and neck sarcoidosis if there is significant inflammation affecting the skin or lymph nodes.

Patients may see improvement in symptoms within a few weeks to months. However, thalidomide is usually reserved for more advanced cases due to its potential side effects.

Leflunomide

Leflunomide is an immunosuppressive drug that helps control inflammation in sarcoidosis.

This medication is typically used in more advanced or refractory cases of sarcoidosis, especially when other treatments have not been effective. It may be used in head and neck sarcoidosis to reduce inflammation in affected tissues.

Patients may see improvement in symptoms over time, but it can take several weeks to months for the full effects to be noticeable. Leflunomide can help prevent further disease progression.
