Introduction: The granular cell tumor was first described by Abrikossoff in 1926. It is a benign, uncommon neoplasia, most frequently found on the tongue. It occurs in the vulva in 5 to 6% of cases. Its histogenesis is not known for sure, but is probably linked to Schawann cells. It is treated surgically, with a good prognosis. The tumors may recur, and some may become malignant according to the literature. The authors describe a case of a vulvar nodule with a histopathologic diagnosis of granular cell tumor, which was successfully treated with surgery.

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.

INTRODUCTION: Vitiligo is an acquired skin dyschromia characterized by the physical and/or functional reduction of melanocytes. We present two surgical proposals for the treatment of vitiligo.
CASE REPORTS: 1) Implant of skin graft diluted in hyaluronic acid gel: We obtained the material through curettage, diluted it in hyaluronic acid gel, and applied it to receptor areas. 2) Epidermal suspension obtained through curettage and diluted in hyaluronic acid gel: After the curettage of the donor area, we treated the material with trypsin-EDTA, centrifuged it, and diluted it in hyaluronic acid gel. The receptor area received the graft.
CONCLUSION: These are safe, easy, and satisfactory surgical procedures for the presented cases.
