研究目的
To report a case of an unusual nevus sebaceus treated successfully with a nonablative fractional 1,550-nm laser.
研究成果
Fractional 1,550-nm laser was a safe and effective treatment for a facial nevus sebaceus with minimal downtime and optimal cosmetic results. Additional prospective studies and post-treatment histology are warranted to determine ideal laser settings, longevity of the results and potential recurrence rates, and general applicability of this approach.
研究不足
Single case report, lack of long-term follow-up data, and absence of post-treatment histology to confirm the mechanism of action.
1：Experimental Design and Method Selection:
A case report of a 24-year-old woman with Fitzpatrick skin Type V presenting with a nevus sebaceus treated with a nonablative fractional 1,550-nm laser.
2：Sample Selection and Data Sources:
Single patient case with clinical photographs and histopathological confirmation.
3：List of Experimental Equipment and Materials:
Nonablative fractional 1,550-nm erbium-doped fiber laser (Fraxel Dual; Solta, Inc., Hayward, CA), 23% lidocaine and 7% tetracaine for topical anesthesia, Cryo 5 for skin surface cooling.
4：Experimental Procedures and Operational Workflow:
Application of topical anesthesia, skin surface cooling, laser treatment with specific parameters, post-treatment care including sunscreen application.
5：Data Analysis Methods:
Clinical assessment of improvement in texture and visibility of the nevus sebaceus by independent physician assessment at 6-month follow-up.
