Ko te Becker's nevus he mate kiri noa e tohuhia ana e te papaki purakau me te tipu o nga makawe (hypertrichosis) ki tetahi taha o te tinana. He maha nga wa ka tukuna ki te lasers, ahakoa kei te noho etahi atu whiringa. Ko nga momo laser rereke kua whakamahia, ko ia anake, ko te tahi ranei, me nga roangaru mai i te 504 ki te 10,600 nm me nga waahi mai i te 1 ki te 12. He rereke nga hua, engari ko te whakakotahi i nga laser me nga roangaru rereke he pai ake te mahi. Ko nga paanga o te taha he ngawari ki te whero (erythema) ngawari. Ahakoa he pai te haumaru o nga lasers, he iti noa te whai huatanga (kaore i te pai) mo te nevus a Becker.
Becker's nevus is a common pigmented dermatosis, usually featured by ipsilateral pigmented patch with hypertrichosis. Becker's nevus is often treated with various types of lasers although other regimens are available. A variety of lasers had been used alone or in combination to treat Becker's nevus. Laser wavelengths used for Becker's nevus ranged from 504 to 10,600 nm, while the number of treatment varied from 1 to 12 sessions. The clinical outcomes were mixed although combination of lasers with different wavelengths appeared to achieve a better efficacy. Adverse effects were usually mild to moderate erythema. While lasers are relatively safe, their efficacy for Becker's nevus is moderate.
