The cutaneous features of tuberous sclerosis: a population study

Area of Science:

• Dermatology
• Genetics
• Pediatrics

Background:

• Tuberous Sclerosis Complex (TSC) is a genetic disorder.
• Cutaneous manifestations are common in TSC.
• Understanding the age-related prevalence of skin lesions is crucial for diagnosis and management.

Purpose of the Study:

• To determine the cross-sectional age-related prevalence of cutaneous features in a defined population with TSC.
• To identify trends in the age of onset for various skin lesions associated with TSC.

Main Methods:

• Cross-sectional study design.
• Inclusion of 131 individuals diagnosed with TSC.
• Documentation and analysis of the prevalence and age of onset for specific skin lesions.

Main Results:

• 96% of individuals with TSC exhibited skin signs.
• Hypomelanic macules and forehead fibrous plaques tend to appear earlier.
• Shagreen patches are typically present by puberty; ungual fibromas can appear as late as the fifth decade.
• Gum fibromas were present in 36% of individuals.

Conclusions:

• Cutaneous manifestations are nearly universal in TSC.
• The age of onset for skin lesions varies significantly.
• Early recognition of specific skin signs can aid in TSC diagnosis and management.
