Nevus comedonicus: an updated review

Area of Science:

• Dermatology
• Genetics
• Pathology

Background:

• Nevus comedonicus (NC) is a rare epidermal nevus.
• It can be associated with nevus comedonicus syndrome, a neurocutaneous disorder.
• Syndromic features include ocular, skeletal, and central nervous system abnormalities.

Purpose of the Study:

• To provide an updated review of nevus comedonicus.
• Focus on clinical features, pathogenesis, and therapeutic options.

Main Methods:

• Literature review of clinical studies and case reports.
• Analysis of recent findings on genetic and molecular pathways.

Main Results:

• NC presents as a distinct epidermal nevus.
• Pathogenesis may involve acne-related signaling pathways and tyrosine kinase receptor mutations.
• Secondary benign skin tumors can develop on pre-existing NC.
• Treatment modalities encompass topical agents, laser therapy, and surgical excision.

Conclusions:

• Nevus comedonicus is a rare condition with potential systemic implications.
• Emerging research points to genetic factors in its pathogenesis.
• A multimodal treatment approach is often necessary.
