Abstract

A nevus is described as a benign, often pigmented, skin growth that can be congenital or acquired. Different types of nevi are located at different depths within the skin. Traditional treatments for nevi include topical treatments, dermabrasion, and excision, which are generally ineffective, invasive, and often result in scars and dyspigmentation. Lately, laser therapy has been used as an alternative. Based on the theory of selective photothermolysis, melanin can be specifically targeted, minimizing adverse effects and increasing effectiveness of laser treatments. Several types of lasers and lights have been studied for this purpose without a concise agreement as to which is the best. In general, quality-switched lasers are preferred for the treatment of pigmented lesions. However, there is controversy about this therapy because certain nevi may have malignant potential. This article serves as a comprehensive review of available laser treatments for nevi and discusses the appropriate measures that should be taken before and after laser therapy. Based on the reviewed literature, laser treatment has generally been proven to be a safe and effective therapy for nevi with minimal side effects.
