皮脂腺瘤（SA）是一种罕见的独立性肿瘤，主要影响前额和头皮。本案例报告的目的是通过使用一种新的扫描系统，确定10600纳米二氧化碳（CO2）激光设备在治疗大面积头皮SA时的疗效和安全性，该系统能够加速病变的清除。一名65岁的男性患者在头皮区接受了一次CO2激光系统的治疗。在此过程中，使用了一种具有7英寸或4英寸焦点手柄的新扫描系统。在激光治疗前进行了利多卡因局部麻醉。检查了一些可能的副作用，如色素沉着、烧灼感、出血以及轻度到中度的治疗后红斑、瘙痒、结痂和水肿。为了监测治疗的有效性，拍摄了临床照片，记录了患者在治疗前和1个月随访时的病变情况。激光治疗后观察到的临床和美观结果非常好，在4周随访时，患者的头皮SA病变完全消失。患者满意度非常高，没有观察到任何副作用。这种激光系统技术能够精确、有效、有针对性地作用于治疗的病变，同时保护周围区域，确保最佳的重新上皮化。版权所有2023年，Bonan et al.

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.Copyright 2023, Bonan et al.
