Successful treatment of Becker’s Nevus with long-pulsed 1064-nm Nd:YAG and 755-nm alexandrite laser and review of the literature

BACKGROUND: Becker's Nevus is an aesthetically troublesome condition secondary to hyperpigmentation and hypertrichosis. Although several lasers have been employed with varying degrees of success, the exact devices and treatment parameters have yet to be elucidated. OBJECTIVE: To assess the combination Nd:YAG and alexandrite laser as a safe and efficacious treatment for Becker's Nevus. METHODS: In a 20-year-old Fitzpatrick Skin Type IV male, a Becker's Nevus was treated with six sessions of long-pulsed 1064 nm Nd:YAG laser at six-week intervals followed by five sessions of long-pulsed 755 nm alexandrite laser at three-month intervals. RESULTS: This patient experienced a significant reduction in both hyperpigmentation and hypertrichosis after these treatment sessions. No serious adverse events were reported. CONCLUSION: This case supports the use of combination long-pulsed 1064 nm laser and 755 nm laser as a safe and efficacious treatment for Becker's Nevus.
