Segmental vitiligo is a small subset albeit persistent form of focal vitiligo with dermatomal distributionand resistant to medical therapy. In recent years, surgical therapy as hair follicle autograft transplantationhas been a hot topic in management of segmental vitiligo. In this study, we evaluated the efficacy of thismethod in segmental vitiligo lesions.
The study recruited 10 patients who suffered from resistant segmental vitiligo to evaluate the effectof transplantation of pigmented hair follicles on re-pigmentation of the affected area. In this method, one or twopunched-biopsy skin sample with a diameter of 5mm were harvested from occipital area of the scalps. Graftswere trimmed and divided into the follicular segments with at least one follicle in the interior and then insertedin the depigmented areas. Follow-up plan studies were scheduled to evaluate presence of pigmentation in theperifollicular areas.
After 2 weeks, re-pigmentation was detectable surrounding the grafted hair follicles in 60 % of thecases. After 6 months, all of the patients had detectable re-pigmented area of about 2-9 mm.
giving the surprising result of the study, hair follicle autograft transplant is an effective treatmentoption in the persistent segmental vitiligo.
节段性白癜风是局限性白癜风中虽小但持续存在的一种类型,具有皮节分布且对药物治疗耐药。近年来,作为毛囊自体移植的手术治疗一直是节段性白癜风治疗中的热门话题。在本研究中,我们评估了该方法在节段性白癜风皮损中的疗效。
本研究招募了10例耐药性节段性白癜风患者,以评估色素性毛囊移植对患区色素再沉着的效果。采用该方法时,从头皮枕部取1个或2个直径5mm的钻孔活检皮肤样本。将移植物修剪并分成内部至少有1个毛囊的毛囊段,然后植入色素脱失区。安排随访计划研究以评估毛囊周围区域色素沉着情况。
2周后,60%的病例在移植毛囊周围可检测到色素再沉着。6个月后,所有患者均有可检测到的色素再沉着区域,面积约为2 - 9mm。
鉴于该研究令人惊讶的结果,毛囊自体移植是持续性节段性白癜风的一种有效治疗选择。
