Successful treatment of extensive vitiligo with monobenzone.

Vitiligo is one of the most common dermatological disorders, appearing as one or more white macules or patches and affecting up to two percent of the population worldwide. The undesirable aesthetic properties of vitiligo, especially facial, may result in significant negative psychosocial effects, particularly a rate of depression twice that of the general population. While there is no cure, there are several treatment options, notably depigmentation in severe cases. Monobenzone is the most potent depigmenting agent. However, its use is limited due to the permanent and potent nature of the drug. This case presents an example of when timely and aggressive treatment with monobenzone is warranted, demonstrating excellent clinical response, which resulted in a significant increase in the quality of life in a patient with severe vitiligo.
