    Pulsed dye laser versus long pulsed Nd:YAG laser in the treatment of angiokeratoma of Fordyce: A randomized, comparative, observer-blinded study.

    J Dermatolog Treat 2016 7;27(3):270-4. Epub 2015 Oct 7.
    a Department of Dermatology , Faculty of Medicine, Al-Azhar University Hospital , Cairo , Egypt.
    Background: Angiokeratoma of Fordyce is typically asymptomatic, blue-to-red papules with a scaly surface located on the scrotum, shaft of penis or labia majora. They can be treated with some locally destructive treatment modalities such as excision, electrocoagulation, cryotherapy and laser.

    Objectives: To compare the effects of the pulsed dye laser versus long pulsed Nd:YAG laser in the treatment of angiokeratoma of Fordyce.

    Methods: Twenty tow patients with angiokeratoma of Fordyce were included in this study. All participants received three sessions of pulsed dye laser on the selected side or part of lesional area and long pulsed Nd:YAG laser on the other side or part of lesional area. Two dermatologists independently evaluated the photographs of the baseline and two-month follow-up after last session using a grade system in which treatment response was categorized into six grades.

    Results: Both PDL and long pulsed Nd:YAG laser revealed statistically significant improvements in angiokeratoma of fordyce. Comparatively, there was a statistical difference between them (overall mean improvement with PDL, 61.8%, versus Nd:YAG, 77.63%; p < 0.005).

    Conclusions: Both PDL and 1064-nm Nd:YAG laser are effective and safe in the treatment of angiokeratoma of Fordyce with better response in Nd:YAG laser than pulsed dye laser.

    Treatment of angiokeratoma of Fordyce with long-pulse neodymium-doped yttrium aluminium garnet laser.
    Dermatol Surg 2009 Jan 8;35(1):92-7. Epub 2008 Dec 8.
    Department of Dermatology, Meram Medical Faculty, Selçuk University, Konya, Turkey.
    Background: Angiokeratomas are typically asymptomatic, blue-to-red papules with a scaly surface located on the scrotum, shaft of penis, labia majora, inner thigh, or lower abdomen. The treatment of angiokeratomas may be necessary if they bleed and lead to patient anxiety.

    Objective: To determine the safety and effectiveness of long-pulse 1,064 neodymium-doped yttrium aluminium garnet (Nd:YAG) laser for the treatment of angiokeratomas of Fordyce. Read More
    Treatment of angiokeratoma of Fordyce with pulsed dye laser.
    Dermatol Surg 2006 Sep;32(9):1147-50
    Department of Dermatology, Tel Aviv University, Tel Aviv, Israel.
    Background: Angiokeratomas of Fordyce are typically asymptomatic vascular lesions characterized by blue-to-red papules with a scale surface, most often located on the scrotum. Although considered benign, the lesions may bleed, either spontaneously or secondary to rupture, leading to patient anxiety and social embarrassment.

    Objective: The objective was to determine the safety and effectiveness of 585-nm pulsed dye laser for the treatment of angiokeratomas of Fordyce. Read More
    Comparative effectiveness of nonpurpuragenic 595-nm pulsed dye laser and microsecond 1064-nm neodymium:yttrium-aluminum-garnet laser for treatment of diffuse facial erythema: A double-blind randomized controlled trial.

    Department of Dermatology, Feinberg School of Medicine, Northwestern University, Chicago, Illinois 60611, USA.
    Background: Facial erythema is a common symptom that responds to vascular laser treatment, but there are few comparative studies.

    Objective: We sought to compare the effectiveness of microsecond 1064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser with nonpurpuragenic 595-nm pulsed dye laser (PDL) for diffuse facial erythema.

    Methods: This was a split-face, double-blind randomized controlled trial. Read More

    Department of Dermatology and Venereology, Faculty of Medicine, Ain Shams University, Cairo, Egypt.
    Background: Different laser systems are reported to be effective in treatment of telangiectasia and erythema, but comparative studies on 1064-nm neodymium-yttrium aluminum garnet (Nd-YAG) laser and pulsed dye laser (PDL) in treatment of erythemato-telangiectatic rosacea are lacking. Substance (P) is implicated in rosacea pathogenesis.

    Objectives: To compare the effect of Nd-YAG laser and PDL on erythemato-telangiectatic rosacea, both clinically and immunohistochemically on cutaneous substance (P) expression. Read More
