Efficacy and Safety of Carbon Dioxide Laser System in the Treatment of Scalp Sebaceous Adenoma With the Use of a New Scanner Unit.

Sebaceous adenoma (SA) is a rare solitary tumor that preferentially affects the forehead and scalp. The objective of this case report was to determine the efficacy and safety of a 10,600-nm carbon dioxide (CO₂) laser device in the treatment of large scalp SA, using a new scanning system which allows to speed up the removal of the lesion. A 65-year-old male with SA on the scalp area underwent one session with the CO₂ laser system. For this procedure, a new scanner system with 7-inch or 4-inch focal handpieces were used. A local anesthesia with lidocaine was performed before laser treatment. Some possible side effects such as dyschromia, burning sensation, bleeding and mild to moderate post-treatment erythema, itching, crusting, and edema, were checked. In order to monitor the effectiveness of the treatment, clinical photos that documented the patient lesion were captured before treatment and at 1 month of follow-up. The clinical and aesthetic results observed after laser procedure were excellent, with a complete remission of patient's scalp SA lesion at 4 weeks' follow-up. Patient satisfaction was very high, and no side effects were observed. This laser system technology allows for precise, effective, and targeted action on the lesions treated while simultaneously protecting the surrounding areas, ensuring the best possible re-epithelialization.
