Yellow nail syndrome
|Yellow nail syndrome|
|Classification and external resources|
Yellow nail syndrome: This patient had a 20-year history of severe lymphedema of her legs; thick, ridged, yellowish, hypercurved thumbnails (top right); similarly affected, yellow-green to brown toenails (bottom right); and bilateral, chylous pleural effusions. A sample of her chylous pleural fluid is shown to the left of the radiograph.
Yellow nail syndrome (also known as "Primary lymphedema associated with yellow nails and pleural effusion":849) is a very rare medical syndrome that includes pleural effusions, lymphedema (due to lymphatic hypoplasia) and yellow dystrophic nails. Approximately 40% will also have bronchiectasis. It is also associated with chronic sinusitis and persistent coughing. It usually affects adults.:665
Normal treatment for swelling and any respiratory problems is appropriate. Nutritional supplementation with Vitamin E in some studies has been shown to be effective in controlling nail changes.
Restated, yellow nail syndrome is characterized by marked thickening and yellow to yellow-green discoloration of the nails often associated with systemic disease, most commonly lymphedema and compromised respiration.:792
There is some evidence it may be caused by titanium, either implanted for medical reasons or through eating various foods containing titanium dioxide. In patients where titanium exposure was thought to be causative, recovery occurred over a period of several months. 
Dramatic improvement in nail discoloration is achieved by oral clarithromycin.
