Melanocyte-Keratinocyte Transplantation in Post-Burn Leukoderma Scars: Preliminary Experience Using a Modified Technique.

Abstract

Post-burn leukoderma, commonly affecting the African and Asian communities, results from deep dermal burns. The associated stigma exacerbates the condition and significantly affects the rehabilitation and reintegration of post-burn survivors into society. Melanocyte-keratinocyte transplantation (MKTP) is a promising single-stage treatment for repigmentation in vitiligo. However, its use in post-burn leukoderma is undetermined. This study aims to evaluate the MKTP treatment in post-burn leukoderma patches. Six patients (five males and one female, mean age = 29±5.51 years) with ten patches of post-burn leukoderma underwent single-stage MKTP without adjuvant pigmentation therapy. The postoperative follow-up period ranged from twelve to twenty-four months for all the patients. The average size of leukoderma treated was 16.25±9 cm². Repigmentation was observed in 92.16±11.05% of the total treated area by the end of one year after MKTP application. All six patients were satisfied with the treatment outcome. MKTP without adjuvant therapy is an effective surgical treatment to treat post-burn leukoderma patches. Future studies should cover a larger sample over a longer follow-up period.
