Autologous noncultured, nontrypsinized melanocyte-keratinocyte graft homogenized in plasma gel followed by narrow-band ultraviolet B therapy for stable vitiligo: A novel technique

There is a continuous need for modifications of epidermal cell grafting techniques treating stable vitiligo to make it easier, more economic, and with better outcome. To evaluate the efficacy and safety of noncultured, nontrypsinized epidermal cell graft homogenized with plasma gel, followed by narrow band-ultraviolet B (NB-UVB) in treatment of stable vitiligo, about 40 patients with stable vitiligo underwent harvesting of epidermal cells from the donor site by dermabrasion then the harvested cells were prepared, homogenized with autologous plasma gel, and applied to the abraded recipient, followed by 16 NB-UVB sessions after complete healing. Patches within the same anatomical site received only NB-UVB as controls. The percentage of improvement ranged from 23.33% to 100% with more than 75% uniform, homogenous repigmentation in 65% of patients. Donor site healed completely with normal skin. Noncultured, nontrypsinized epidermal cell grafting technique homogenized with plasma gel followed by NB-UVB sessions gave positive responses and was well tolerated in different body sites in stable resistant vitiligo.
