Zosteriform collagen nevus in a young boy

Area of Science:

• Dermatology
• Histopathology
• Genetics

Background:

• Connective tissue nevi are rare hamartomas composed of collagen, elastin, or glycosaminoglycans.
• Zosteriform distribution is an uncommon presentation for connective tissue nevi.
• First described by Steiner in 1944, these nevi represent a diverse group of conditions.

Observation:

• A pediatric case of a zosteriform connective tissue nevus is presented.
• The patient exhibited a nevus with a characteristic zosteriform (shingles-like) pattern.
• Histopathological examination confirmed the presence of a collagen nevus.

Findings:

• The case represents a rare instance of a collagen nevus manifesting in a zosteriform arrangement.
• This presentation deviates from typical patterns of connective tissue nevi.
• The findings contribute to the understanding of the phenotypic variability of connective tissue nevi.

Implications:

• This case expands the known clinical spectrum of zosteriform connective tissue nevi.
• It underscores the importance of considering rare presentations in dermatological diagnosis.
• Further research may elucidate the specific genetic or developmental factors underlying this rare zosteriform pattern.
