Hypertrichotic Becker's nevi treated with combination 1,550 nm non-ablative fractional photothermolysis and laser hair removal

Background: The removal of Becker's nevi poses a significant challenge due to limited available therapeutic options and increased risk of adverse effects, including scarring and dyspigmentation. Herein, we present the use of the non-ablative fractional photothermolysis in combination with laser hair removal for the treatment of hypertrichotic Becker's nevi.

Method: Retrospective analysis of three patients with Becker's nevi revealed that two patients with hypertrichotic Becker's nevi had greater than 75% clearance with combination therapy, and one patient with atrichotic Becker's nevus had a similar result with monotherapy non-ablative fractional photothermolysis.

Conclusion: This report demonstrates the utility and safety of combination non-ablative fractional resurfacing and laser hair removal for the treatment of hypertrichotic Becker's nevi, and monotherapy non-ablative fractional photothermolysis for atrichotic Becker's nevi. Further comparative studies are necessary to determine optimal laser parameters, treatment schedules, and response duration.
