[Yellow nail syndrom--clinical signs and differential diagnosis (author's transl)]

This report describes 3 cases of yellow nail syndrom. The examination either did not reveal lymphedemas or only transitory edemas were found. But both typical changes of nails and chronic inflammation of the respiratory tract were found. Remarkably enough, two of our patients showed a decrease in serum immunoglobulin M (IgM). Both patients had a most serious disorder of the respiratory tract. In the form of a table this report contains a survey of the literature published hitherto about the combinations of symptoms of yellow nail syndrom occurring most frequently.
