Epidermal curettage technique (ECT) for tissue harvest from the donor area for melanocyte autologous grafting in cases of vitiligo*
نویسندگان
چکیده
Vitiligo is a dermatosis requiring complex treatment. In clinically stable cases, melanocyte autologous grafting has shown good results, using different methodologies for obtaining the donor area: dermatomes, punches, blisters. However, these techniques are complex and require specific instruments. This study presents a simple technique for melanocyte harvest that has been performed in our service for more than ten years and includes epidermal curettage of the donor area, grafting of the obtained material, which was homogenized with saline or hyaluronic acid, on the achromic area, and the application of a semipermeable dressing that is removed 1 week later.

Vitiligo: analysis of grafting versus curettage alone, using melanocyte morphology and reverse transcriptase polymerase chain reaction for tyrosinase mRNA.
CONTEXT AND OBJECTIVE Recent studies have indicated that vitiligo areas contain inactive or dormant melanocytes. Melanin synthesis is related to tyrosinase presence and indicative of active metabolic state. The aim of this study was to compare repigmentation, epidermal melanocyte distribution and tyrosinase mRNA detection through reverse transcriptase polymerase chain reaction, in tissue sample...

BACKGROUND AND AIMS Stable vitiligo can be treated by various surgical procedures. Non-cultured melanocyte grafting techniques were developed to overcome the time-consuming process of culture while at the same time providing acceptable results. All the techniques using non-cultured melanocyte transfer involve trypsinisation as an integral step. Jodhpur technique used by the author is autologous...

Background: Different modalities have been tried in order totreat stable vitiligo. Culturing melanocytes is time consumingand expensive. Therefore, new methods using autologousmelanocytes are sought. We aimed to compare the mixed nonculturedautologous melanocytes of the outer root sheath andthe bulge area of hair follicle transplantation plus dermabrasionwith dermabrasion alone in stable genera...

BACKGROUND Vitiligo is a chronic disease characterized by the appearance of achromic macules caused by melanocyte destruction. Surgical treatments with melanocyte transplantation can be used for stable vitiligo cases. OBJECTIVES To evaluate treatment response to the autologous transplantation of noncultured epidermal cell suspension in patients with stable vitiligo. METHODS Case series stud...
