I applaud Qin et al. for their publication, “Photodynamic therapy of port wine stains – a report of 238 cases”1. Such extensive experience with photodynamic therapy (PDT) for port wine stains (PWS) is impressive and I believe, unequaled in the Western world. In the United States and Europe, pulsed lasers and light sources, especially the pulsed dye laser (PDL; wavelengths = 585 or 595 nm) are t...

Port- wine stain is a congenital vascular malformation originating from superficial dermal vessels which is characterized by ectasia of the capillaries. Currently, pulsed dye laser (PDL) is used to treat these vascular lesions. To date, there are few reports of eczematous lesions due to PDL. Herein, we report three cases of eczema following PDL, used for treatment of port- wine stain in Razi ho...

BACKGROUND Hypertrophic scars affect 1.5% to 4.5% of the general population and remain notoriously difficult to eradicate because of the high recurrence rates and the incidence of side effects associated with treatment. Pulsed dye laser (PDL) treatment and intralesional corticosteroids have individually been reported to be effective in reducing hypertrophic scar bulk and symptoms. OBJECTIVE T...

PURPOSE Although pulsed dye laser (PDL) treatment of port-wine stain (PWS) has long been proven safe and effective, incomplete clearance of these vascular malformations can be problematic. In addition, advanced PWS with deeper coloration and tissue hypertrophy can be particularly difficult to treat because of the superficial dermal penetration of 585- to 595-nm light. The purpose of this study ...

introduction:  no modality has been identified as the treatment of chice for treating common warts. cryothearpy and pulsed-dye laser (pdl) are among common modalities for treating these lesions. the aim of this study was to compare pulsed dye laser with cryotherapy in terms of efficacy and complications. methods:  of a total of 46 patients enrolled in this study, 7 patients withdrew the study, ...

OBJECTIVE To compare the clinical response of keloidal and hypertrophic scars after treatment with intralesional corticosteroid alone or combined with 5-fluorouracil (5-FU), 5-FU alone, and the 585-nm flashlamp-pumped pulsed-dye laser (PDL). DESIGN Prospective, paired-comparison, randomized controlled trial. SETTING A private ambulatory laser facility. PATIENTS Ten patients with previousl...

The exact reason for the effectiveness of pulsed light at a wavelength of 585–595 nm of PDL in the treatment of CLE lesions is unclear. With laser therapy, the applied light is monochromatic, and there is strong evidence that the induced pathogenic mechanisms are different from those caused by irradiation over an ultraviolet spectrum. The suggested working mechanism of PDL (selective phototherm...

BACKGROUND AND OBJECTIVE Pulsed dye laser (PDL) treatment of cutaneous vascular lesions is associated with variable and unpredictable efficacy. Thus, alternative treatment modalities are needed. Previous in vitro and in vivo studies have demonstrated enhanced selective vascular destruction with benzoporphyrin derivative (BPD) monoacid ring A photodynamic therapy (PDT) followed immediately by PD...
