Peeling skin syndrome with hair changes

Area of Science:

• Dermatology
• Genetics
• Pediatrics

Background:

• Peeling Skin Syndrome (PSS) is a rare genetic disorder characterized by generalized or partial non-inflammatory peeling of the skin.
• The inflammatory variant of PSS (Type B) presents with additional inflammatory skin signs.
• The genetic basis and full clinical spectrum of PSS are still being elucidated.

Observation:

• A 13-year-old male patient presented with clinical features consistent with inflammatory PSS (Type B).
• The patient displayed significant and previously undescribed hair anomalies.
• These anomalies included trichorrhexis invaginata-like changes, irregular hair shaft torsions, and moniliform hair shaft diameter reductions.

Findings:

• The co-occurrence of PSS and distinct hair dysplasias was observed in this patient.
• Microscopic examination revealed specific structural abnormalities in the hair shafts.
• These hair abnormalities represent a novel finding in the context of Peeling Skin Syndrome.

Implications:

• The findings suggest that hair anomalies may be an underrecognized component of the dermatosis in certain PSS variants.
• This case expands the known clinical phenotype of PSS, particularly Type B.
• Further research is warranted to understand the genetic and molecular links between PSS and hair shaft abnormalities.
