BACKGROUND: Noncultured epidermal cell suspension transplantation is a very popular surgical modality for treating vitiligo. However, the procedure can be modified to improve results.
OBJECTIVE: To study the extent of repigmentation with noncultured trypsinized fragmented epidermal suspension using platelet-rich plasma (PRP) as a suspending agent and pixel erbium yttrium aluminium garnet laser for ablation of recipient area in patients with stable vitiligo.
MATERIALS AND METHODS: Autologous noncultured tiny epidermal fragments suspended in PRP were grafted on superficially pixel erbium YAG laser-ablated vitiligo lesions in 10 patients. The repigmentation was evaluated over a period of 6 months using a digital image analysis system.
RESULTS: Repigmentation was observed as early as 2 weeks after the treatment. Of 20 lesions, 12 (60%) showed excellent response; of which 10 lesions (50%) showed complete repigmentation in 8 weeks only. There were no milia or keloid formation, donor-site scarring, stuck on appearance at recipient site or infection.
CONCLUSION: This study indicates that PRP-enriched epidermal suspension transplant (LA-PEEST) has the potential to improve the rate of healing and repigmentation in vitiligo patches. Further investigations and larger controlled trials are required to establish this technique as a rapid surgical method to restore pigmentation.
