Background: 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.
Methods: 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.
Results: 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.
Conclusion: giving the surprising result of the study, hair follicle autograft transplant is an effective treatmentoption in the persistent segmental vitiligo.

This article is based on a roundtable discussion in which three panelists review clinically relevant insights about vitiligo and discuss two cases that illustrate the multiple challenges faced by both patients and clinicians in managing this complex disease. The first is a 32-year-old White female patient with Fitzpatrick Skin Type III/IV with extensive depigmentation in the trunk area. The patient achieved 90-percent repigmentation with a combination therapy approach.

Vitiligo is a common autoimmune disease that progressively destroys melanocytes in the skin, resulting in the appearance of patchy depigmentation. The aim of this review is to increase awareness towards vitiligo by providing insight on the pathogenesis and management options. Vitiligo is an acquired pigmentary skin disease, which can appear with one or a few macules.

Background: Previous studies have proven that 308-nm light-emitting diode(308-nm LED)and 308-nm excimer lamp(308-nm MEL) are effective in treating vitiligo, but there is a lack of comparison of their efficacy for facial lesions.
Objective: To evaluate and contrast the treatment success rates of 308-nm LED versus 308-nm excimer lamp in managing facial lesions among patients suffering from stable non-segmental vitiligo.
Methods: The enrolled 119 patients with 145 lesions were randomly assigned to receive 308-nm LED or 308-nm MEL for two months.

Vitiligo, alopecia areata, atopic, and stasis dermatitis are common skin conditions that pose diagnostic and assessment challenges. Skin image analysis is a promising noninvasive approach for objective and automated detection as well as quantitative assessment of skin diseases. This review provides a systematic literature search regarding the analysis of computer vision techniques applied to these benign skin conditions, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
