Multiple lichen striatus--an unusual presentation.

Area of Science:

• Dermatology
• Pediatric Dermatology
• Genodermatology

Background:

• Lichen striatus is an inflammatory skin condition.
• It typically presents as a unilateral, linear eruption of papules or macules.
• Lesions often follow Blaschko lines.

Purpose of the Study:

• To describe unusual presentations of lichen striatus.
• To document cases with multiple Blaschko lines in distinct anatomical areas.
• To contribute to the understanding of lichen striatus variability.

Main Methods:

• Case report of two pediatric patients.
• Clinical observation of skin lesions.
• Documentation of lesion distribution along Blaschko lines.

Main Results:

• A 2-year-old mare child presented with bilateral hypopigmented papules along Blaschko lines.
• A 7-year-old girl presented with hypopigmented macules linearly distributed on limbs and back along Blaschko lines.
• Three discrete lines across distinct anatomical areas were observed in one case, a presentation not previously described.

Conclusions:

• Lichen striatus can exhibit diverse and extensive patterns.
• Presentations involving multiple Blaschko lines in separate anatomical regions are possible.
• Further research is needed to understand the full spectrum of lichen striatus.
