Plasma radiofrequency ablation for treatment of benign skin lesions: Clinical and reflectance confocal microscopy outcomes

BackgroundIn the latest few years, plasma radiofrequency ablation has turned out a good option for treatment of several benign skin lesions. The technique can be easily performed to treat skin lesions with limited tissue invasion and no residual scars or hypo/hyperpigmentation areas. ObjectiveThe aim of this study was to assess the effects of plasma radiofrequency ablation in treatment of benign skin lesions, through clinical and reflectance confocal microscopy outcomes. MethodsSix patients who presented benign skin lesions underwent long-wave plasma radiofrequency ablation treatment with DAS medical device (Technolux, Italia). Reflectance confocal microscopy analysis was performed at baseline and after 1 month. ResultsThe treatment was well tolerated; only a slight erythema and a thin crust on the treated area were referred for 3-7 days after treatment. After one month from treatments, we observed the complete disappearance of the lesions and no significant signs of inflammation, redness, hypo/hyperpigmentation, or scars on the site of the treated areas; these clinical data were also confirmed by reflectance confocal microscopy analysis. ConclusionsLong-wave plasma radiofrequency ablation actually can be considered a well-tolerated, painless, safe, effective, and low-cost procedure for skin treatments.
