Noonan syndrome.
The Noonan syndrome is a rare disease characterized by dysmorphic facies, short stature, ear abnormalities, cryptorchidism, ocular abnormalities, cardiovascular anomalies, cubitus valgus, webbed neck, and cutaneous and hair abnormalities. Some 25% to 40% of patients have dermatologic abnormalities. Diagnosis is purely clinical, and intrauterine diagnosis is very important based on the presence of cystic hygroma and evidence of myocardial abnormalities. Treatment is symptomatic. Genetic counseling is necessary.
