Comparing the Efficacy of 2 Different Harvesting Techniques for Melanocyte Keratinocyte Transplantation in Vitiligo

Vitiligo is a dermatologic disorder caused by autoimmune-mediated destruction of melanocytes. Surgical treatment is indicated for stable vitiligo lesions. Recent advances have established melanocyte keratinocyte transplantation procedure (MKTP) as an effective treatment and its 45% average percent change in vitiligo area scoring index is documented by recent studies. In addition, studies have demonstrated that suction blistering technique is a more uniform way to remove the epidermis without inducing scars, making it safer and more beneficial than surgical methods to remove the epidermis. To develop an innovative and improved procedure, we sought to compare the result of MKTP harvesting with a blade, and MKTP harvesting with a suction blister, to determine whether using different harvesting techniques would affect the outcome.
