Treatment of maxillofacial congenital melanocytic nevus with percutaneous radiofrequency thermal ablation: A case series study

Dufourmentel Flap for Surgical Treatment of Medium-sized Congenital Melanocytic Nevi on the Extremities

Congenital melanocytic nevi (CMN) are quite common benign proliferations of cutaneous melanocytes. They are present at birth or arise during the first few weeks of life being upper and lower extremities one of the most common locations. To date consistent guidelines for clinical management of CMN do not yet exist and the main reasons for removing them are medical and cosmetic. Regardless of the cause of having a CMN removed, when it comes to surgical excision of the lesion in daily practice the single most important decision to make is how to properly close the post-excisional defect. The local Dufourmentel skin flap seems to be a reliable solution for surgical treatment of medium-sized CMN on the limbs. It takes advantage of skin laxity adjаcent to thе defect to allоw the transpositiоn of tissuе with similаr charactеristics tо the tissuе еxcisеd which is the key for achieving good aesthetic and functional outcomes. In this brief clinical study the author identified a group of adult patients who had medium-sized CMN located on their extremities. The surgical technique is explained and useful tips are given. No complications and high patient satisfaction rate were registered in the series. Dufourmentel flap is a useful tool in the armamentarium of dermatologic surgery when dealing with medium-sized CMN on the extremities. Furthermore, due to its versatility this flap could also be applied for other clinical indications both benign and malignant.
