Neonatal Noonan syndrome with a molluscoid cutaneous excess over the scalp.

We report an observation of a newborn with Noonan syndrome and an unusual molluscoid cutaneous excess over the scalp that might represent a new skin manifestation in Noonan Syndrome rather than a consequence of lymphatic dysplasia.
