Ectodermal Dysplasia-Skin Fragility Syndrome: A Rare Case Report

Area of Science:

• Genetics
• Dermatology
• Molecular Biology

Background:

• Ectodermal dysplasia/skin fragility syndrome (ED-SFS) is a rare autosomal recessive disorder.
• It is characterized by skin fragility, blistering, palmoplantar keratoderma, abnormal hair and nail growth, and sometimes defective sweating.
• Mutations in the PKP1 gene, encoding plakophilin 1, cause ED-SFS, affecting epithelial desmosomes and nuclear function.

Purpose of the Study:

• To report an unusual case of ED-SFS in a pediatric patient.
• To describe the clinical presentation and key features of this rare genodermatosis.
• To contribute to the limited case reports of ED-SFS.

Main Methods:

• Clinical case presentation of a 12-year-old boy.
• Detailed description of dermatological and physical findings.
• Review of existing literature on ED-SFS and PKP1 gene mutations.

Main Results:

• The patient presented with skin fragility, hair and nail deformities, abnormal dentition, palmoplantar keratoderma, and abnormal sweating.
• The patient had no systemic abnormalities.
• The clinical presentation aligns with previously reported cases of ED-SFS.

Conclusions:

• ED-SFS is a rare genodermatosis with a distinct set of clinical features.
• PKP1 gene mutations are the underlying cause of ED-SFS.
• This case expands the understanding of ED-SFS presentation, particularly the absence of systemic involvement.
