Yellow nails syndrome is a rare disease characterised by a triad of, yellow nails, pleural and lung involvement and primary lymphoedema. Its origin still remains unclear, but lymphatic return disturbance has been suggested as the reason of all its signs. We present this case because of the importance of diagnosing this syndrome and to rule out other associated diseases (malignancies, HIV, tuberculosis, thyroid disease, rheumatoid arthritis) as the diagnosis of the disease is easy if cardinal signs are known, particularly the condition of the nails (yellow nails and halted nail growth). Many possibilities have been proposed on the treatment of this syndrome,including, oral itraconazole, oral vitamin E, and zinc supplements, but the low prevalence of the disease and the possibility of spontaneous healing makes it difficult to evaluate the real effectiveness of the different treatments.
