Use of the 532-nm Q-switched neodymium-doped yttrium aluminum garnet laser for the treatment of recalcitrant repigmentation in vitiligo

Vitiligo is a disorder characterized by the development of depigmented patches and macules. Patients with extensive involvement may opt for complete depigmentation using monobenzyl ether of hydroquinone (MBEH).1 However, after depigmentation, a subset of patients note repigmentation that is significantly darker than their original skin tone and is resistant to treatment with MBEH.2 Here we present a vitiligo patient who had recalcitrant repigmentation after depigmentation with MBEH, which was responsive to treatment with the 532-nm Q-switched neodymium-doped yttrium aluminum garnet (QS Nd:Yag) laser.
