Cutaneous manifestations of Noonan's syndrome.

Noonan's syndrome is a multisystem syndrome that has received little attention in the dermatologic literature, although there are numerous cutaneous manifestations that have been described. A typical case of Noonan's syndrome is presented. Clinical findings in this patient included short stature, curly scalp hair, prominent ears, hypertelorism, webbing of the neck, cubitus valgus, pigmented nevi, stasis dermatitis, and plantar hyperkeratosis. The latter two findings have not been previously reported in Noonan's syndrome. We urge that dermatologists become more aware of this syndrome to document the spectrum of changes that may occur in Noonan's syndrome.
