Multiple pilomatricomas in twins with Rubinstein-Taybi syndrome

Area of Science:

• Dermatology
• Clinical Genetics
• Oncology

Background:

• Pilomatricomas are benign skin tumors arising from the hair follicle's matrix.
• Multiple pilomatricomas are uncommon, often associated with myotonic dystrophy or familial adenomatous polyposis.
• The association between pilomatricomas and genetic syndromes, particularly Rubinstein-Taybi syndrome, is infrequently reported.

Observation:

• Rubinstein-Taybi syndrome is a rare autosomal dominant disorder with characteristic intellectual disability and dysmorphic features.
• Previous reports have suggested a link between multiple pilomatricomas and Rubinstein-Taybi syndrome, with five case reports documented.
• This study details the first observed instance of multiple pilomatricomas in monozygotic twins who both exhibit typical Rubinstein-Taybi syndrome characteristics.

Findings:

• The co-occurrence of multiple pilomatricomas in monozygotic twins with Rubinstein-Taybi syndrome provides compelling evidence for a potential genetic association.
• This case strengthens the hypothesis that Rubinstein-Taybi syndrome may predispose individuals to developing multiple pilomatricomas.

Implications:

• Further research is warranted to elucidate the specific genetic mechanisms underlying the co-occurrence of pilomatricomas and Rubinstein-Taybi syndrome.
• This finding may influence clinical surveillance and diagnostic approaches for patients with Rubinstein-Taybi syndrome.
• Understanding this association could lead to improved genetic counseling and management strategies for affected families.
