Lymphedema in Noonan's syndrome.

Chronic edema can be debilitating in Noonan's syndrome. Transient childhood lymphedema may be followed by elephantiasis as early as adolescence. Recurrent streptococcal cellulitis exacerbates this problem. Hygenic measures and prophylactic antiobiotic therapy may slow progression of lymphedema of the legs in Noonan's syndrome.
