Treatment of Trauma-Induced Vitiligo

Initial Assessment and Stabilization

The American Academy of Dermatology recommends avoiding all trauma to unaffected skin areas to prevent new lesion formation, as the Koebner phenomenon will continue to generate new depigmented patches with ongoing injury 2
Applying adequate lubrication to reduce friction-related trauma and minimize mechanical stress on the skin is advised 2
Documenting disease extent with photographs using the VASI or VETF scoring systems to monitor treatment response objectively is recommended 3, 1
Checking thyroid function before starting treatment due to high prevalence of autoimmune thyroid disease in vitiligo patients is necessary 1, 4

The National Institute for Health and Care Excellence recommends potent or very potent topical corticosteroids as the primary treatment option, with clobetasol propionate 0.05% or betamethasone valerate 0.1% applied for a trial period of no more than 2 months 1, 2
Studies show 15-25% repigmentation in approximately 43% of patients, with >75% repigmentation in about 9% of cases using highly potent steroids 3
Topical calcineurin inhibitors (tacrolimus or pimecrolimus) should be considered as alternatives with comparable efficacy but better safety profiles, particularly for facial or eyelid involvement 1

The British Association of Dermatologists recommends narrowband UVB (NB-UVB) phototherapy as preferred over PUVA, offering greater efficacy and better safety profile, particularly for darker skin types 1, 2
A safety limit of no more than 200 treatments for skin types I-III is advised 1

Surgical treatments should only be considered when there have been no new lesions, no Koebner phenomenon present, and no extension of existing lesions for at least 12 months 1, 2
Split-skin grafting provides better cosmetic results than minigraft procedures 1
Autologous epidermal suspension is optimal but requires special facilities and should be followed by NB-UVB or PUVA therapy 1

Never perform surgical treatments in patients with active Koebnerization or recent disease progression, as this will exacerbate the condition and create new depigmented areas 2
Do not extend potent topical steroid use beyond 2 months to avoid skin atrophy 2
Failing to prevent ongoing trauma will result in continued disease progression regardless of treatment efficacy 2
Do not overlook the psychological impact, as trauma-induced vitiligo can be particularly distressing; offer psychological interventions to improve coping mechanisms 1, 2

Continue trauma avoidance strategies indefinitely to prevent reactivation of the Koebner phenomenon 2
Consider cosmetic camouflage, including fake tanning products, which can improve quality of life 3
