Clinical repigmentation patterns in paediatric vitiligo

Area of Science:

• Dermatology
• Clinical Research

Background:

• Repigmentation is a key outcome in vitiligo treatment.
• Limited clinical data exists on vitiligo repigmentation patterns.

Purpose of the Study:

• To define vitiligo repigmentation patterns.
• To correlate patterns with patient characteristics.

Main Methods:

• Retrospective review of 109 vitiligo patients (2006-2014).
• Analysis of clinical photographs and medical records.
• Evaluation of 172 vitiligo lesions.

Main Results:

• Combined repigmentation pattern was most frequent (62%).
• Combined pattern more common in segmental vitiligo; diffuse pattern more frequent in nonsegmental.
• A novel 'medium spotted repigmentation' pattern was observed.

Conclusions:

• The combined repigmentation pattern is most prevalent.
• Medium spotted repigmentation is a newly identified pattern requiring further investigation.
