Aim Lasers and non-coherent intense pulse light sources (IPLS) are based on the principle of selective photothermolysis and can be used for the treatment of many vascular skin lesions. A variety of lasers has been developed for the treatment of congenital and acquired vascular lesions which incorporate these concepts into their design. Although laser and light sources are very popular due to their non-invasive nature, caution should be considered by practitioners and patients to avoid permanent side-effects. The aim of these guidelines is to give evidence-based recommendations for the use of lasers and IPLS in the treatment of vascular lesions. Results Lasers and IPLS are very useful and sometimes the only available method to treat various vascular lesions. It is of a paramount importance that the type of laser or IPLS and their specific parameters are adapted to the indication but also that the treating physician is familiar with the device to be used. The crucial issue in treating vascular lesions is to recognize the immediate end-point after laser treatment. This is the single most important factor to ensure both the efficacy of the treatment and avoidance of serious side-effects. Methods Conflicts of interestNone declared. Funding sourceNone.Since the publication of previous European Society of Laser Dermatology (ESLD) guidelines in 2007, there have been significant advances in the field of laser treatment of common vascular lesions.1 These guidelines have been updated by the Consensus Panel under the auspices of the ESLD. Methodology, search strategy and recommendation formulation are described in Appendix II. A brief overview of vascular lasersStandard vascular lasers include pulsed dye lasers (585 and 595 nm), and KTP-lasers (532 nm), followed by longer wavelength lasers such as alexandrite lasers (755 nm), diode lasers (800-900 nm) and millisecond Nd:YAG lasers (1064 nm). New developments include a non-uniform pulse sequence or a dual-wavelength modality (combined dual wavelength 595 and 1064 nm-pulsed dye and Nd:YAG laser) and microsecond Nd: YAG lasers. [2][3][4][5][6] Even fractional photothermolysis has begun to be used for selected vascular lesions. Lasers' and intense pulse light sources (IPLS) effects are based on the principle of selective photothermolysis. In general, they deliver a precisely graded aliquot of energy to a defined area of the skin in a reproducible, standardized manner that almost always involves addition or evacuation of heat.

“…In addition, the 532-nm KTP laser has been used to treat angiokeratomas of not only the scrotum (in combination with a 10,600-nm ablative carbon dioxide laser to remove the epidermal hyperkeratosis) [ 24 ], but also the glans penis (in combination with a 2,940-nm ablative Er:YAG laser to eliminate hyperkeratosis of the epidermis) [ 36 ]. Finally, the 532-nm KTP laser has successfully treated nongenital angiokeratoma [ 37 ] and other vascular lesions [ 32 , 34 , 38 – 41 ].…”

Scrotal rejuvenation encompasses not only the functional quality but also the aesthetic appearance of the scrotum. It includes medical therapy and procedural interventions to improve scrotal conditions that require morphologic restoration and/or aesthetic alteration. Rejuvenation of the scrotum may be appropriate for aging-related and non-aging-related changes concerning the hair (alopecia and hypertrichosis), the morphology (laxity and wrinkles), and/or the vascularity (angiokeratoma) of the scrotum. Angiokeratomas—typically small, asymptomatic, purple papules—may occur on the scrotum. However, these benign vascular lesions may be of cosmetic concern to the affected individuals; in addition, the angiokeratomas can become an issue of medical importance if they begin to bleed. Multiple locally destructive modalities are available for the treatment of scrotal angiokeratomas; indeed, several lasers have effectively been used to treat angiokeratomas of the scrotum. A 70-year-old man with numerous scrotal angiokeratomas experienced scrotal bleeding in the absence of prior trauma to the area or sexual activity. He presented for treatment to prevent future episodes of spontaneous bleeding from his scrotal angiokeratomas, but he also had not liked the aesthetic appearance of the previously asymptomatic angiokeratomas on his scrotum. His angiokeratomas were successfully treated with three sequential 532-nm potassium titanyl phosphate (KTP) laser sessions, which led to not only functional but also cosmetic improvement of his scrotum. In conclusion, men can develop scrotal changes due to either intrinsic (aging) or extrinsic (trauma) causes, but nonsurgical interventions and surgical procedures are available for the management of these conditions in individuals who desire to rejuvenate their scrotum.

“…This laser is capable of high‐power output delivering up to 850 W at 532 nm out of the handpiece. It has shown efficacy in PWS, leg veins, and facial telangiectasias (Figures ) . The main disadvantage to the 532 nm wavelength produced by these lasers is the greater absorption of energy by epidermal melanin with a greater risk of pigmentary changes, especially in tanned or darker skin types.…”
