BACKGROUND/OBJECTIVES: Phototherapy is a commonly used treatment for vitiligo that has demonstrated safety and efficacy. High-intensity targeted ultraviolet B (UVB) light (304-312 nm) delivered using a phototherapy device is a useful therapeutic option because it can induce repigmentation in a short time without global exposure to radiation, but information regarding this device in children is limited. METHODS: We performed a retrospective analysis of 95 patches of vitiligo in 27 children treated using a targeted phototherapy device...

The pathogenesis of vitiligo involves interplay between intrinsic and extrinsic melanocyte defects, innate immune inflammation, and T-cell-mediated melanocyte destruction. The goal of treatment is to not only halt disease progression but also promote repigmentation through melanocyte regeneration, proliferation, and migration. Treatment strategies that address all aspects of disease pathogenesis and repigmentation are likely to have greatest efficacy, a strategy that may require combination therapies. Current treatments generally involve nontargeted suppression of autoimmunity, whereas emerging treatments are likely to use a more targeted approach based on in-depth understanding of disease pathogenesis, which may provide higher efficacy with a good safety profile...

The general goals of medical management of vitiligo are to repigment vitiliginous areas of skin and to stabilize the progression of depigmentation. However, for some patients with vitiligo affecting extensive body surface areas who are unresponsive to repigmentation therapies, depigmentation of the remaining normal skin may be a better choice. Candidates for depigmentation therapy should be carefully screened and patient education is essential. Permanent topical therapies used for depigmentation include monobenzyl ether of hydroquinone, 4-methoxyphenol, and 88% phenol...

Repigmentation in vitiligo is the process that replaces, in the epidermal basal layer of vitiligo skin, the mature melanocytes that have been killed by cytotoxic T cells specific for melanocyte antigens. It consists of mobilization of melanocyte precursors in the hair follicle bulge and infundibulum to proliferate, migrate, and differentiate into mature melanocytes, moving from the hair follicle bulge to the interfollicular epidermis. The most common clinical presentation of repigmentation in vitiligo is the perifollicular pattern...

Surgical management is a safe and effective treatment modality for select patients with vitiligo. Many techniques of vitiligo surgery exist, each with unique advantages and disadvantages. Preoperative screening for appropriate candidates, selection of surgical technique, and postoperative management are all key elements in enabling patients to achieve maximal repigmentation.

Medical treatments alone, or in combination with phototherapy, are key approaches for treating nonsegmental vitiligo and, to a lesser extent, segmental vitiligo. The treatments are useful for halting disease progression and have been proven effective for inducing repigmentation and decreasing risk of relapses. Although the treatments have side effects and limitations, vitiligo often induces a marked decrease in quality of life and in most cases the risk:benefit ratio is in favor of an active approach. Systemic and topical agents targeting the pathways involved in loss of melanocytes and in differentiation of melanocyte stem cells should provide more effective approaches in the near future...

The relative genetic and immune protection against melanoma and nonmelanoma skin cancers in those with vitiligo is reassuring. The results of recent studies allow us to be cautiously optimistic when discussing the risk of skin cancer caused by therapeutic exposure to narrow-band ultraviolet B light. However, we should continue to recommend sun protection at all other times to avoid burning in vitiliginous skin and to decrease incidental ultraviolet exposure. It is also important to perform full skin checks regularly in light of the prolonged courses of phototherapy required to repigment vitiliginous skin and maintain repigmentation thereafter...

Skin color is determined by the number of melanin granules produced by melanocytes that are transferred to keratinocytes. Melanin synthesis and the distribution of melanosomes to keratinocytes within the epidermal melanin unit (EMU) within the skin of vitiligo patients have been poorly studied. The ultrastructure and distribution of melanosomes in melanocytes and surrounding keratinocytes in perilesional vitiligo and normal skin were investigated using transmission electron microscopy (TEM). Furthermore, we performed a quantitative analysis of melanosome distribution within the EMUs with scatter plot...

Vitiligo is the most frequent human pigmentary disorder, characterized by progressive autoimmune destruction of mature epidermal melanocytes. Of the current treatments offering partial and temporary relief, ultraviolet (UV) light is the most effective, coordinating an intricate network of keratinocyte and melanocyte factors that control numerous cellular and molecular signaling pathways. This UV-activated process is a classic example of regenerative medicine, inducing functional melanocyte stem cell populations in the hair follicle to divide, migrate, and differentiate into mature melanocytes that regenerate the epidermis through a complex process involving melanocytes and other cell lineages in the skin...

Vitiligo is a common pigmentary disorder of the skin with a great amount of social stigma attached to it. Though various medical modalities are available for the treatment of stable vitiligo, surgical modality remains the treatment of choice for stable and localized vitiligo. The surgical options range from simple punch grafting to the recent epidermal harvesting methods using a negative pressure unit. Although successful use of multiple methods of epidermal grafting has been reported, most of them are cumbersome and time-consuming...
