Yellow Nail Syndrome
Overview
What is yellow nail syndrome?
Yellow nail syndrome is a rare condition that affects your nails, lungs and limbs. People with yellow nail syndrome get yellow, curved nails that may thicken or fall off. They also may have respiratory symptoms, such as a chronic cough, and usually have swollen lower legs or ankles.
Experts don’t know what causes yellow nail syndrome. But it may be linked to improper circulation, issues with lymphatic drainage or buildup of fluid around your lungs. You may also have a higher risk if you have one of a few specific chronic diseases, dental implants or a joint replacement.
Who might get yellow nail syndrome?
Yellow nail syndrome develops most often in adults over 50. More rarely, yellow nail syndrome sometimes occurs in children.
Some reports show higher rates of yellow nail syndrome in people with:
Autoimmune diseases.
Cancer.
Nephrotic syndrome.
Rheumatoid arthritis (RA).
Thyroid disease.
Symptoms
What are the symptoms of yellow nail syndrome?
Yellow nail syndrome has three main types of symptoms:
Nail changes: Your nails may grow slower or stop growing. They usually become thick, yellow or green and may detach from your nail bed and fall off. Nail changes may affect one or all nails.
Swelling: Fluid buildup and swelling (lymphedema) affect about 8 in 10 people with yellow nail syndrome. Most often, your legs swell a few months after nail changes.
Respiratory symptoms: Almost 2 in 5 people with yellow nail syndrome have fluid buildup in lung tissue (pleural effusions). You may also have a chronic cough, repeat sinus infections (sinusitis) or pneumonia.
Yellow nail syndrome is more than discolored or stained nails. Many people have yellow nails without having yellow nail syndrome. For example, you may have yellowish nails for a short time after removing dark nail polish. But if the color doesn’t go away within a few weeks, or if you have other symptoms, see your healthcare provider.
What does yellow nail syndrome look like?
The hallmark sign of yellow nail syndrome is yellowish nails that curve and thicken. You may experience:
Breakdown of your cuticles, the thin skin that protects your nailbed.
Nail curving.
Nail separation from your nailbed.
Nail ridges.
Slowed or stopped nail growth.
What causes yellow nail syndrome?
Experts don’t know what causes yellow nail syndrome. Most people develop the syndrome for no known reason.
Some experts believe that yellow nail syndrome results from issues with your circulatory or lymphatic system. When these systems don’t work as they should, it can cause fluid to collect in the soft tissues under your skin. In turn, this may turn your nails yellow.
Some researchers think that yellow nail syndrome is genetic. There may be a link between a mutation (change) in the FOXC2 gene and yellow nail syndrome. FOXC2 gene mutations cause a condition called lymphedema-distichiasis syndrome. This condition has similar symptoms to yellow nail syndrome.
Other researchers think there’s a link between yellow nail syndrome and titanium exposure. Joint replacements, dental implants and certain medications can increase your titanium exposure. But most people with titanium implants don’t develop yellow nail syndrome.
Diagnosis
How is yellow nail syndrome diagnosed?
Usually, your healthcare provider can diagnose yellow nail syndrome based on your symptoms. You may also have:
Pulmonary function tests to assess your lung health.
Nail tests to rule out other nail conditions, such as an infection.
Yellow nails could point to many conditions, such as a fungal infection or psoriasis. But if you have yellow nails along with respiratory symptoms, your healthcare provider might need to rule out yellow nail syndrome.
Treatment
How do you treat yellow nail syndrome?
Your healthcare provider will treat yellow nail syndrome according to the suspected underlying cause or condition. For example, if they suspect improper lymph drainage, they may recommend specialized massage to help improve your circulation. If yellow nail syndrome is associated with excess fluid around your lungs, your healthcare provider may recommend a procedure to drain the fluid.
Other yellow nail syndrome treatments may include:
Vitamin E: You may take vitamin E supplements or apply a nail cream or gel containing vitamin E. Nail symptoms aren’t usually reversible, but vitamin E can slow or halt the progression of nail changes.
Corticosteroids: You may use steroid creams to treat nail symptoms and reduce inflammation. Common options include fluocinonide (Lidex®), hydrocortisone (Cortizone-10®, Locoid Lipocream®) or desoximetasone (Topicort®).
Antibiotics: You may take antibiotics such as amoxicillin (Amoxil®, Trimox®) or cefadroxil (Duricef®) to treat a respiratory infection that keeps returning.
