Yellow nail syndrome is commonly associated with what symptoms?

Yellow nail syndrome is characterized primarily by a combination of specific symptoms, with the most notable being the yellow discoloration of the nails and lymphedema, which is the swelling due to the accumulation of lymph fluid. This syndrome is also associated with respiratory issues and other systemic conditions. The yellow nails can have a distinctly thickened appearance, and individuals may notice that the nails grow slower than normal.

Lymphedema adds to the characteristic presentation of the syndrome, often resulting in swelling, particularly in the legs and ankles. This combination of yellow nails and lymphedema is what defines yellow nail syndrome and sets it apart from other conditions. The other symptoms listed, such as red, itchy skin, greenish discoloration of the skin, or a rash on the feet, do not align with the hallmark features of yellow nail syndrome, making the option that includes yellow nails and lymphedema the correct choice.
