Supplementary Material for: Successful treatment of poikilodermatous mycosis fungoides with 308-nm excimer laser

Introduction: Among the spectrum of mycosis fungoides (MF), poikilodermatous MF (PMF) is a rare clinical variant of patch-stage MF, which is characterized by cutaneous atrophy, mottled-reticular pigmentation, and telangiectasia. Given its favorable prognosis, ultraviolet (UV) light therapy, such as narrowband UVB (NB-UVB), is commonly employed for the treatment of PMF. Notably, the 308-nm excimer laser emits high-energy monochromatic light with a wavelength close to the NB-UVB peak. Case presentation: Herein, we report a case of PMF successfully treated with the 308-nm excimer laser.
Conclusion: There have been no English-language case reports describing the use of excimer laser treatment for PMF, and this is the first English report that suggests the usefulness of the 308-nm excimer laser for the treatment of PMF, which is one of the clinical variants of patch-stage of MF.

引言：在蕈样肉芽肿（mycosis fungoides, MF）的疾病谱系中，异色病样蕈样肉芽肿（poikilodermatous MF, PMF）是一种罕见的斑片期MF临床亚型，以皮肤萎缩、网状斑驳色素沉着及毛细血管扩张为特征。鉴于该亚型预后良好，临床常采用紫外线（ultraviolet, UV）光疗（如窄谱UVB（narrowband UVB, NB-UVB））治疗PMF。值得注意的是，308纳米准分子激光（308-nm excimer laser）可发射波长接近NB-UVB峰值的高能单色光。病例报告：本文报告1例采用308纳米准分子激光成功治疗的PMF病例。结论：目前尚无英文病例报道描述准分子激光用于PMF的治疗，本报告为首篇证实308纳米准分子激光对PMF具有治疗价值的英文文献，而PMF正是斑片期MF的临床亚型之一。
