Pulmonary involvement in tuberous sclerosis.

Tuberous sclerosis is a neurocutaneous syndrome involving many tissues. Pulmonary involvement is rare. Pulmonary cases are usually women of child-bearing age who present with spontaneous pneumothorax or progressive dyspnea. In childhood and, even more, in male patients, pulmonary involvement by tuberous sclerosis is exceptional. We report on a 4-year-old male patient diagnosed in the first months of life with tuberous sclerosis with predominantly respiratory symptoms (frequently with acute RDS criteria), in whom lung involvement was pathologically confirmed.
