Clinical Study attributes
Vitiligo is the most common acquired depigmented disorder of the skin characterized by destruction of melanocytes resulting in well-circumscribed achromic macules. Ultraviolet phototherapy with narrow band (UVB-NB) is currently one of the treatments of choice, because it is able to induce proliferation, differentiation, maturation and migration of melanocytes. This repigmentation has distinctive patterns such as follicular, marginal, and diffuse. The aim of this study is to observe the dynamics of migration and proliferation, in vitiligo patients under UVB radiation phototherapy treatment. The investigators will evaluate this process by measuring FAK (focal adhesion kinase ) and c-Kit by immunohistochemistry and reverse transcriptase polymerase chain reaction assay.
