Depigmented hair. The earliest sign of tuberous sclerosis
Insights
A white tuft of scalp hair is an early indicator of tuberous sclerosis complex (TSC) in newborns. This finding, present at birth, can appear months before skin lesions, aiding early diagnosis in infants.
Area of Science:
- Pediatric Neurology
- Dermatology
- Genetics
Background:
- Tuberous sclerosis complex (TSC) is a genetic disorder.
- TSC can manifest with various neurological and dermatological symptoms.
- Early diagnosis of TSC is crucial for management.
Purpose of the Study:
- To identify early clinical signs of tuberous sclerosis complex in newborns.
- To investigate the diagnostic significance of scalp hair depigmentation in TSC.
Main Methods:
- Case study of 4 children diagnosed with tuberous sclerosis complex.
- Clinical observation and parental reporting of scalp hair changes.
- Correlation of hair findings with the onset of other TSC manifestations.
Main Results:
- All 4 children presented with depigmented scalp hair patches noted at birth.
- In one case, a white hair tuft preceded skin macules by several months.
- Scalp hair examination revealed a potential early diagnostic marker.
Conclusions:
- A white tuft of scalp hair is a valuable early sign of tuberous sclerosis complex in neonates and young children.
- Routine examination of scalp hair is recommended for unexplained early seizures in infants.
- Early identification of TSC through hair anomalies can facilitate timely intervention.
Abstract:
We have studied 4 children with tuberous sclerosis with one or more patches of depigmented scalp hair and in each case these were noticed by the parents at birth. In one patient the finding of a tuft of white hair preceded the appearance of white macules by many months. A tuft of white scalp hair is a useful new sign of tuberous sclerosis in the newborn and young child, and the hair should be examined as carefully as the skin when early 'organic' seizures are unexplained.
