Abstract

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-pumped pulsed 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 pulse duration 100nanoseconds and 3mm 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. The results were as follows ; 1) Excellent and good responses were observed in nevus spilus, freckles, senile lentiginesand Peutz-Jegher's syndrome. 2) Fair responses were observed in melanocytic nevus, Hocker's nevus. 3) Poor responses were observed in melasma and cafe-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.
