Quality-Switched Ruby Laser Treatment of Solar Lentigines and Becker’s Nevus: A Histopathological and Immunohistochemical Study

Abstract

We found that pigmented lesions featuring a moderate amount of pigment exclusively in and around the basal cell layer, like solar (actinic) lentigo, can be successfully removed by a single QSRL exposure selectively damaging epidermal and basal pigmented structures. Further investigations concerning QSRL treatment of dermally pigmented skin lesions have to be initiated.
