Vitiligo is an acquired dyschromia of the skin in which there is a loss of epidermal
melanocytes. The prevalence of vitiligo is approximately 1% in the United States and
0.1-2% worldwide. The exact pathogenesis of vitiligo remains elusive and is likely multifactorial.
After completing this update, participants should be able to discuss the epidemiology
of vitiligo and summarize the proposed mechanisms for development of this
disease. In addition, they should be able to discuss physical findings, approach to the
patient, and some of the therapeutic modalities for this disorder.
