Many conventional modalities such as dermabrasion, depigmenting creams as well as several types of lasers have been used for the treatment of cutaneous pigmented lesions without countable effects.
Flashlamp-pumed pulse dye laser(PLTL-1) is one of the selective photothermolysis laser. This laser system incorporates two separate lasers, having an emission wave length of 510nm, a pulse duration 400nanoseconds and 5mm spot size, a
flashlamp-excited
pulsed dye laser is used to treat superficial cutaneous lesions, and flashlamp-excited, Q-switched alexandrite laser(TATULAZR), having an emission wavelength of 755nm, a pulsse duration 100nanoseconds and 3m spot size is designed for the
treatment
of
blue-black tatoos.
Purpose of this study is to evaluate efficacy of PLTL-1 laser for treatment of cutaneous pigmented lesions.
@ES The results were as follows;
@EN 1) Excellent and good responses were observed in nevus spilus, freckles, senile lentigines and Peutz-jegher's syndrome.
2) Fair responses were observed in melanocytic nevus, Becker's nevus.
3) Poor responses were observed in melasma and caf*-au-lait spot.
4) Good to fair responses were observed in nevus of Ota, ABNOM, and tattoos.
5) There were mild complications such as transient hyperpigmentation, transient hypopigmentation and recurrence.
