The Argon laser has been used in the treatment of port wine stains, telangiectasias, spider ectasias, ruby spots, venous lakes, pyogenic granulomas, tattoos, keloids, verrucous naevus, angiokeratomas, verrucous hemangiomas. The outcome results have been compared with those achievable using other treatments in order to give right indications to the use of the Argon laser. The comparison point out that Argon laser is the treatment of choice only in port wine stains, while in all the other diseases it doesn't give any advantage with regard to conventional therapies, less sophisticated, easier and sometime more effective.
