Summary
This study shows that combining surgical leukoderma treatments with additional mini-grafting effectively restores pigmentation in vitiligo and piebaldism patients. This approach significantly improves depigmented defects, offering a complete restoration for most.
Area of Science:
- Dermatology
- Regenerative Medicine
- Surgical Oncology
Background:
- Refractory vitiligo and piebaldism often resist medical treatments.
- Melanocyte transplantation offers a surgical option for repigmentation in select cases.
Purpose of the Study:
- To assess the effectiveness of supplementary mini-grafting (1.0-1.2 mm punch grafts) in achieving complete depigmented defect restoration post-leukoderma surgery.
- Evaluating additional grafting techniques for surgical leukoderma correction.
Main Methods:
- Eight patients with stable, refractory leukoderma underwent melanocyte transplantation.
- Procedures included epidermal shave, suction epidermal grafting, and in vitro cultured epidermal autografts.
- All patients received additional mini-grafts to address residual achromia.
Main Results:
- Complete (100%) restoration of depigmented defects was achieved in seven out of eight patients.
- The remaining patient experienced an 80% improvement in depigmentation.
Conclusions:
- Surgical correction of leukoderma, when augmented with additional mini-grafting, can successfully restore depigmented areas.
- This combined approach is beneficial for achieving complete repigmentation, particularly when residual achromia persists after initial treatments.
