[Dermatologic manifestations of tuberous sclerosis in children. A study of 6 cases].

Typical cutaneous findings in tuberous sclerosis are present in over 90% of cases and represent one of the earliest markers of the syndrome. Our study, based on 6 pediatric cases, underlines how the skin manifestations vary with the patient's age. Hypopigmented maculae were usually present at birth and remained often the only clinical sign during the first few years of age. Angiofibromas on the face appeared later and were followed by orange-peel patches and then by periungual fibromas. The high spontaneous new mutation rate of tuberous sclerosis seems to be confirmed by our study in which clinical evaluation of first-degree relatives of all patients was negative.
