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. However, clinical outcomes appear inconsistent among studies. To summarize the clinical outcomes of Becker's
nevus treated with
lasers via literature review. 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. It seems that combination
therapy could improve the outcome. However, trials in larger group of patients are required to validate the efficacy of each type of
lasers for Becker's
nevus.
