Vitiligo is an acquired dyschromia that affects 0,1-3% of the world population and can cause significant psychosocial distress in patients. Surgical management became essential in the last years. Mini-punch grafting is one of the cheapest and most straightforward approaches to all surgical treatments available. A limitation of this technique is the possibility of cobblestone-like repigmentation. We describe a new technique with a dermoepidermal grafting obtained by shave excision of papule formed post punch grafting in vitiligo. It could improve the cobblestone pattern in the donor site and the repigmentation in both donor and recipient areas.
