BACKGROUND: Vitiligo is a chronic disease characterized by the appearance of achromic macules caused by melanocyte destruction. Surgical treatments with melanocyte transplantation can be used for stable vitiligo cases. OBJECTIVES: To evaluate treatment response to the autologous transplantation of noncultured epidermal cell suspension in patients with stable vitiligo. METHODS: Case series study in patients with stable vitiligo submitted to noncultured epidermal cell suspension transplantation and evaluated at least once, between 3 and 6 months after the procedure, to observe repigmentation and possible adverse effects...

Introduction: Recently, the monochromatic excimer light (MEL) of 308 nm wavelength has shown some advantages in comparison to narrow band ultraviolet B (NB-UVB) for the treatment of vitiligo. To histopathologically compare the early effects of NB-UVB and 308-nm MEL phototherapy on vitiliginous patches using H&E and HMB-45. Methods: Thirty subjects with non-segmental vitiligo lesions were treated twice a week for 6 weeks with 308-nm MEL, while NB-UVB was used to treat lesions contra laterally. Skin biopsies were taken from lesional areas before and after 6 weeks of treatment by either modality...

In recent years, laser toning or laser facial to treat melasma has become increasingly popular in Asia. It is common to see patients undergoing lasers three times a week, or even daily. This is part of a growing trend and is sometimes recommended in the user manuals from laser manufacturers. In our study, we report on 23 Chinese patients who had lasers performed three times a week for two consecutive months, followed by rest. All 23 of them developed bilateral confetti-like hypopigmentation at the end of two months...

BACKGROUND: Recently, we introduced intralesional injection of autologous epidermal cells as a safe and feasible approach for transplantation in patients with stable vitiligo. This approach resulted in less pain during and after the procedure, no scarring or cobblestone formation at the recipient site, and was more feasible to perform on curved surfaces such as joints, lips, eyelids, ears, and face. OBJECTIVE: In this study, we aimed to investigate the long-term efficacy and safety of this transplantation technique...

BACKGROUND/PURPOSE: Vitamin D has a role in variety of autoimmune diseases including vitiligo. Narrow-band UVB (NB-UVB) treatment of vitiligo might act through its effects on vitamin D and its receptor.This study is the first to elucidate NB-UVB effects on immunohistochemical vitamin D receptor (VDR) expression in generalized vitiligo and correlate it with serum vitamin D and repigmentation response. METHODS: Using immunohistochemistry, VDR expression was estimated in skin biopsies of 30 controls and 30 vitiligo patients; from vitiligo lesion, perilesional skin at baseline and from repigmented and nonresponding skin after 24 NB-UVB sessions...

Significant skin pigmentation changes occur when patients suffer deep burn injuries. These pigmentation disorders may cause not only cosmetic and psychological issues, but more importantly it increases the risk of skin cancer or photoaging. Severe burns significantly effect on the process of repigmentation as the pigmentation is tightly regulated by cell proliferation and differentiation of melanocytes and melanocyte stem cells which are housing in the epidermis and hair follicles of the skin. In the present review, we discuss the possible mechanisms to replenish the melanocytes from the healthy epidermis and hair follicles surrounding burn wounds...

Recent studies on congenital melanocytic nevi (CMN) indicate a lower risk for melanoma than assumed for many years. As a result, the treatment paradigm in CMN shifted from complete removal to cosmetically acceptable, less invasive treatment options such as laser treatment. Our objective was to systematically review the efficacy and safety of laser therapy for CMN. We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and PubMed. We rated the quality of evidence with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach...

Vitiligo repigmentation is a complex process in which the melanocyte-depleted interfollicular epidermis (IE) is repopulated by melanocyte precursors from hair follicle (HF) bulge that proliferate, migrate, and differentiate into mature melanocytes on their way to the epidermis. The strongest stimulus for vitiligo repigmentation is narrow band UVB (NBUVB), but how the HF melanocyte precursors are activated by UV light has not been extensively studied. To better understand this process, we developed an application that combined laser capture microdissection and subsequent whole transcriptome RNA sequencing of HF bulge melanocyte precursors, and compared their gene signature to that of regenerated mature epidermal melanocytes from the NBUVB-treated vitiligo skin...

Systemic drug treatment of vitiligo is currently limited to predominantly adjuvant measures for increasing the effectiveness of UV light therapy. We here present new approaches for the systemic treatment of vitiligo currently under clinical investigation. These include the α‑MSH-analogue afamelatonide and oral immunosuppressants such as the Janus kinase (JAK) inhibitors which target interferon-α-dependent autotoxic inflammatory reactions. In 2015 the first publications on the successful systemic use of Janus kinase (JAK) inhibitors in vitiligo appeared...

This study evaluated frequency-dependent effects of extremely low frequency electromagnetic fields (ELF-EMFs) on melanogenesis by melanocytes in vitro. Melanocytes were exposed to 2 mT EMFs at 30-75 Hz for 3 days before melanogenesis was examined. Exposure to ELF-EMFs at 50 and 60 Hz induced melanogenic maturation without cell damage, without changing cell proliferation and mitochondrial activity. Melanin content and tyrosinase activity of cells exposed to 50 Hz were higher than in controls, and mRNA expression of tyrosinase-related protein-2 was elevated relative to controls at 50 Hz...

Laser ablation is recently suggested as a most effective and reliable technique for depigmentation of melanin hyperpigmented gingiva. To date, different lasers have been used for gingival depigmentation (CO2, diode, Nd:YAG, Er:YAG and Er,Cr:YSGG lasers). The use of Er:YAG laser for depigmentation of melanin hyperpigmented gingiva has gained increasing importance in recent years. The purpose of this study was to report removal of gingival melanin pigmentation using an Er:YAG laser in a literature review. The main outcomes, such as improvement of signs (clinical parameters of bleeding, erythema, swelling and wound healing), symptoms (pain) and melanin recurrence/repigmentation were measured...

BACKGROUND: Noncultured, extracted follicular outer root sheath suspension (NC-EHF-ORS-CS) is a recently introduced technique for the treatment of stable vitiligo. OBJECTIVE: To study the clinical efficacy of this technique and to determine the viability and cell composition of the suspension.

Punctate leukoderma presents as numerous, distinct, round or oval depigmented spots. Recently, laser therapy-induced punctate leukoderma associated with various Q-switched laser and carbon dioxide laser have been reported. A 25-year-old man presented with numerous, discrete, round, confetti-like, depigmented macules on his left neck. He had undergone 3 sessions of 532-nm Q-switched Neodymium: Yttrium-Aluminum-Garnet laser treatment for café-au-lait macules three years ago. After the last laser treatment session, the punctate leukoderma had been developed...

Vitiligo is a disorder characterized by the development of depigmented macules and patches secondary to melanocyte destruction. Several treatment options are available, including medical, light-based, and surgical therapies, that are often used in combination to achieve maximal repigmentation. Vitiligo surgery is an effective yet underperformed treatment, mainly because of lack of awareness and availability. The purpose of this article is to review one method of vitiligo surgery, the melanocyte-keratinocyte transplantation procedure, and discuss its utility in treating vitiligo...
