INTRODUCTION Several studies have reported laser treatment of Capillary Malformations (CMs) using systems other than pulsed dye lasers (PDL). Few, however, have compared different systems in the same patients. This study aimed to directly compare CM fading using five different systems. METHODS Eighteen previously PDL-treated patients were test-patched using the alexandrite, KTP, and Nd:YAG la...

OBJECTIVE Laser treatment of port-wine stain (PWS) might be improved using a deeply penetrating wavelength. METHODS PWSs in 17 patients were treated 3 times with a 595-nm pulsed dye laser (PDL) and a 1064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser. Fluences of 1.0, 0.8, and 0.6 times the minimum purpura dose (MPD) were used for Nd:YAG laser. Posttreatment biopsy specimens were taken....

BACKGROUND Keloids are abnormal wound responses characterised by excessive deposition of collagen and glycoprotein. They are both aesthetically and symptomatically distressing for most of the patients. There are reports of keloid management with pulsed dye laser (PDL), fractional carbon dioxide (CO2) laser and neodymium-doped yttrium aluminium garnet (Nd:YAG) laser individually and also in comb...

BACKGROUND Nodular amyloidosis is a rare form of primary localized cutaneous amyloidosis which is characterized by single or multiple nodules located on the extremities, trunk, genitalia, or face. OBJECTIVE To determine the clinical and histologic response of nodular amyloidosis to pulsed dye laser treatment. METHODS Biopsy-proven amyloid nodules were treated with a 585-nm pulsed dye laser ...

Laser treatment of vascular skin lesions is rapidly improving. Port wine stain (PWS) is one of the first lesions successfully treated with laser. The pulsed dye laser (PDL) has been developed on the concept of selective photothermolysis and has revolutionized PWS treatment. Even though the response is variable, substantial blanching can be obtained after several sessions. Greater selectivity an...

OBJECTIVE Cutaneous telangiectases are a characteristic and psychologically distressing feature of SSc. Our aim was to assess the efficacy of two light-based treatments: pulsed dye laser (PDL) and intense pulsed light (IPL). METHODS Nineteen patients with facial or upper limb telangiectases underwent three treatments with PDL and IPL (randomly assigned to left- and right-sided lesions). Outco...

Background Port-wine stain (PWS) birthmarks currently are treated using a pulsed dye laser (PDL) combined with transient cooling of the epidermis. PDL treatment protocols utilize short pulses of light (585 or 595 nm wavelength) to heat selectively the microvasculature due to absorption by intravascular hemoglobin. Although most patients respond to PDL therapy, few experience complete removal of...

BACKGROUND AND OBJECTIVES The average success rate in achieving total blanching of port wine stain (PWS) lesions treated with laser-induced selective photothermolysis is below 25%, even after multiple treatments. This is because smaller diameter (5-20 microm) PWS blood vessels are difficult to destroy with selective photothermolysis since the volumetric heat generated by absorption of laser lig...

BACKGROUND AND OBJECTIVES Both the diagnosis and the treatment of lichenoid dermatosis are often difficult and can be time-consuming. There are now more and more publications about the use of laser systems--especially the flashlamp-pumped pulsed dye laser--in the treatment of inflammatory dermatoses, although the laser's exact mechanism of action in these cases is not yet clear.

Molluscum contagiosum is a common cutaneous disease that may be difficult to treat when there are multiple lesions; especially in children. This study was conducted to determine the efficacy of pulsed dye laser (585 nm) in the treatment of molluscum contagiosum in 20 children. In the treated group, 70.5% of lesions healed after the first treatment; the remaining 10.6% after the second treatment...
