Recently, atopic dermatitis has been increasing throughout the world, and there have been many labial lentigos caused by a postinflammation of atopic dermatitis.1 Laser therapy, such as the normal ruby laser2 and the Q-switched ruby laser,3 is one of the treatment methods. We make the first report of 4 cases of labial lentigos in atopic dermatitis treated with the frequency-doubled Q-switched Nd:YAG laser at a wavelength of 532 nm. We achieved rapid results and a dramatic clearing of the lesions without cutaneous alterations in skin texture.
