Nevus Pigmentado Piloso Gigante: Acompanhamento clínico e histopatológico de três anos após remoção com Laser Q-Switched Nd.YAG 1064nm

Giant congenital melanocytic nevi are extremely rare, however there is a 5-10% chance they will develop into melanomas. Laser-based treatment of this type of lesion is still very controversial. Some studies report great success without malignant development and others have achieved good aesthetic results but with malignancy. This article describes the clinical and histological development of a case of a female patient with a giant congenital melanocytic bathing trunk nevus, after 14 sessions of 1,064 nm Q-Switched Nd:YAG laser and three years of follow-up without histological signs of malignancy. The authors highlight the need for histological monitoring of this type of lesions.
