title: Aplasia of toe phalanges and nails.
abstract: An infant born without toenails and without the middle and distal phalanges of the toes was otherwise normal, on clinical and radiological examination. This is the second case of this entity to be described. It is speculated that an environmental insult at the critical period of fetal toe development may be the cause of the anomaly, but a genetic factor cannot be excluded.
