[Tuberous sclerosis: a multidisciplinary study of 15 cases].

Report of a multidisciplinary study of patients affected with tuberous sclerosis, 8 of them males and 7 females, with ages ranging from 19 months to 23 years; 11 of these cases were sporadic, while the remaining 4 cases lacked information regarding family data. The following skin signs were observed: Pringle's adenoma in 9 cases; achromatic spots in 9 cases; periungueal fibroma in 3 cases. One of the patients had a heart tumor. Two patients had borderline intelligence, while the other 13 were mentally retarded of varying degrees. Epileptic seizures were present in 13 patients, atypical absence and tonus crises were frequent. Three of the patients had had infantile spasms in the first year of life as the first neurological symptom of the disease. Computer assisted axial tomography was performed in 7 cases and was positive in all of them, by revealing intracranial calcifications even in 4 cases in which the standard X-ray pictures had been silent about this eventuality.
