Yellow nail syndrome presenting as non-immune hydrops: second case report.

The yellow nail syndrome is characterized by slowly growing yellow discolored nails and lymphoedema, with onset generally after puberty. We report on a newborn infant who, at 23 weeks, was found to have hydrops on antenatal ultrasonography and bilateral chylothorax at delivery. His mother has the yellow nail syndrome, with typical nail changes, and bronchiectasis. There seemed to be no other etiology for the non-immune hydrops, and this is the second documented case of the prenatal manifestation of this condition.
