Yellow nails, known as xanthonychie in medical parlance, are generally a symptom of onychomycosis
, that is to say a growth of microscopic fungi under the nail. Onychomycosis can be caused by maceration of the skin in shoes, a phenomenon that occurs in a hot and humid environment favored by fungi. Treatment generally consists of removing the infected nails and applying an antifungal
substance that will eradicate the fungus. There is also a very rare syndrome for which the cause is unknown called yellow nail syndrome, where patients not only have yellow nails, but suffer from varied pulmonary problems, susceptible to infection, as well as skin problems, with lymphedema in the lower limbs (swelling of the legs secondary to an obstruction in lymph circulation).
