Abstract
BACKGROUND Treatment management for congenital melanocytic nevi (CMN) on the face (FCMN) is highly variable and requires a thorough assessment of multiple factors. To date, a systematic review of FCMN treatment is lacking. The purpose of the present study was to elucidate the frequency, variety, and outcomes of treatment modalities for FCMN with different levels of complexity. METHODS A comprehensive review of Pubmed, Embase, and Google Scholar databases from 1950 to 2022 was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Articles reporting on FCMN treatment approaches, outcomes, and associated complications were screened and data were extracted according to inclusion criteria. Data were tabulated for thematic analysis of FCMN treatment types, anatomic locations, outcomes, and complications. RESULTS Of the 561 studies retrieved, 34 met inclusion criteria including 19 surgical treatments, 14 nonsurgical treatments, and one combined surgical and nonsurgical treatment study, totaling 356 patients. The majority of treated FCMN were small-to-medium-sized (56%). Facial CMN treated conservatively were mostly located on the cheek (27%) and/or perinasal region (21%), whereas FCMN treated with surgery were primarily located in the periorbital region (44%) and/or the cheek (17%). Across all treatment cohorts, 22% of patients experienced at least one complication, with 12% of complications experienced by patients treated by surgery. CONCLUSIONS There is a greater need for standardized FCMN nomenclature that encompasses nevi pattern, dimensions, anatomical coverage, and quantitative measurements of treatment outcome. Future studies should focus on identifying anatomic locations of FCMN that are more prone to complications and determine which treatment approach optimizes outcomes.

Abstract
A nevus is described as a benign, often pigmented, skin growth that can be congenital or acquired. Different types of nevi are located at different depths within the skin. Traditional treatments for nevi include topical treatments, dermabrasion, and excision, which are generally ineffective, invasive, and often result in scars and dyspigmentation. Lately, laser therapy has been used as an alternative. Based on the theory of selective photothermolysis, melanin can be specifically targeted, minimizing adverse effects and increasing effectiveness of laser treatments. Several types of lasers and lights have been studied for this purpose without a concise agreement as to which is the best. In general, quality-switched lasers are preferred for the treatment of pigmented lesions. However, there is controversy about this therapy because certain nevi may have malignant potential. This article serves as a comprehensive review of available laser treatments for nevi and discusses the appropriate measures that should be taken before and after laser therapy. Based on the reviewed literature, laser treatment has generally been proven to be a safe and effective therapy for nevi with minimal side effects.

Abstract
This report describes treatment combining Ultrapulse CO(2) laser and Q-switched frequency-doubled neodymium:yttrium-aluminum-garnet (Nd-YAG) laser for a number of congenital nevocellular naevi (CNN). The Ultrapulse CO(2) laser removes the superficial component, which contains most of the color, preserving the integrity of the reticular dermis. At a later stage, any residual color is targeted using the Nd-YAG laser. To date, a total of 10 histologically proven CNNs have been treated at the Laser Suite. The median age of the patients was 18 years (range, 13-24 years). All the patients were white females. The patients accepted for treatment had relatively small lesions (mean surface area, 352 mm(2); range, 50-1,092 mm(2)), but the lesions were either cosmetically sensitive or located in an anatomically critical area in which excision could result in a scar that would be unpredictable. The median follow-up period was 24 months. The overall results have been satisfactory, with reduction of color and no significant scarring. The minor textural and pigmentary changes were acceptable to the patients.

Abstract
BACKGROUND A variety of treatment options exist for the management of congenital nevomelanocytic nevi (CNN). Surgical treatment has been the traditional approach, but scarring and cosmetic problems are common. Recently, lasers have been used to treat CNN because, in some cases, surgical excisions are inadequate owing to their inaccessible location, size, and depth. OBJECTIVE The effects of the combined use of CO2 laser and Q-switched Alexandrite laser on CNN were evaluated. METHODS Eleven patients with CNN were enrolled in this study. The surface epithelium was abraded by a CO2 laser. Subsequently, the lesion was treated by a Q-switched alexandrite laser. Repeated treatments were done every 6 weeks. The results were evaluated clinically by both physicians and patients at 2 and 6 weeks after each treatment using a 5-point grade scale. RESULTS By the end of the treatments, the average improvement scale assessed by the physicians, with a 5-point grade scale, was 3.82 and that of the patients was 3.73. There were no cases of hypertrophic scar or postinflammatory hyperpigmentaton persisting beyond 2 weeks. There were no recurrences during the 2-year follow-up period. CONCLUSION The combined laser treatment is an effective method for the treatment of CNN. The clinical outcome was favorable; the treatment was safer, less painful, and relatively nonscarring; and there was a quicker recovery period and less of a burden to repeat treatment when necessary compared with conventional treatments.

Abstract
Patients presenting with congenital melanocytic nevi (CMN) need individualized treatment based upon nevus size, thickness, location, risk for developing melanoma, and psychological characteristics of the patient and family. The present authors review CMN types and prognoses, as well as absolute and relative indications for treatment. Risks and benefits of several treatment options are discussed, including surgical options, such as excision, chemical peels, dermabrasion and curettage, and laser therapy. The main focus of treatment is, in all cases, to address the concern for developing melanoma, at the same time optimizing the aesthetic and functional outcomes.

Abstract
Congenital nevi are benign proliferations present at birth that consist of cells normally present in the skin. Many of these lesions are disfiguring and a source of psychosocial impairment. Because of location or extent of the lesion, surgical excision of the nevus may leave a defect without favorable reconstructive options. Laser ablation of such lesions has been used by several clinicians. A review of laser terminology is presented along with a review of nevus of Ota, nevus of Ito, café-au-lait macules, lentigines, and congenital melanocytic nevi. Although good results may be achieved with laser ablation of these lesions, laser treatment modalities for congenital melanocytic nevi remain controversial because of the potential for malignancy.

Abstract
Clinical response of congenital melanocytic nevus (CMN) to the combined normal-mode ruby laser (NMRL) and Q-switched ruby laser (QSRL) treatment method (ie, NM plus QS) was correlated with the histologic depth of nevomelanocytic nests to predict the efficacy rate and therapeutic outcome of the laser treatment. Thirty-four patients with CMN were treated using the combined (NM plus QS) ruby laser method. The clinical results of the laser treatment demonstrated that 20 had excellent response, 11 had good response, 3 had fair response, and there was no poor response. When correlated with the histologic type, the efficacy rate of the combined ruby laser was significantly higher in the superficial intradermal type than in the others. We conclude that combining the NMRL and QSRL with appropriate parameters to target both superficial and deep nevomelanocytic components provides a greater degree of penetration of laser light.

Abstract
BACKGROUND Q-switch-mode laser treatment of congenital nevi does not result in complete histological clearance, and many patients have partial repigmentation within several months. In addition, the number of recurrent pigmented macules (RPMs) may increase, a major drawback to good cosmetic results. While the mechanism of recurrence is not known. OBJECTIVE To help elucidate the mechanism of RPM development, we evaluated the expression of TNF-alpha and E-cadherin on RPM after treatment of congenital nevi with a Q-switched alexandrite laser (QSAL). METHODS Thirteen Korean subjects with congenital nevi received QSAL treatment at intervals ranging from 2 to 6 months (mean, 4.5 treatments). Two-millimeter punch biopsy specimens were obtained at their first visit and from RPMs 3-6 months after the last treatment. Expression of E-cadherin and TNF-alpha were determined histochemically in the original nevi and RPM. In addition, one RPM was examined by electron microscopy. RESULTS Reduced pigmentation in the treated areas was seen in all cases, but partial repigmentaion was seen as black spots within 6 months after the last QSAL treatment. Compared to the original nevi, the RPMs had increased numbers of melanocytes in the epidermis and reduced nevomelanocytic nests in the dermis. The expression of TNF-alpha and E-cadherin was downregulated in the RPMs compared to the original nevi. Electron microscopy confirmed the increase in melanocytes in the epidermis of RPMs. CONCLUSION Our findings suggest that the down-regulation of E-cadherin and TNF-alpha may induce the proliferation of melanocytes, resulting in the formation of RPMs.

Abstract
We report a combination procedure that can improve the effectiveness of laser removal of giant congenital melanocytic nevi (CMN). A 2-year-old girl with a giant CMN was seen in our outpatient clinic. Histological findings showed a compound nevus without any evidence of malignancy or dysplastic changes. The patient was treated with the normal mode ruby laser and Q-switched alexandrite laser. The lesion was significantly improved in color and cosmetic appearance. Partial hypopigmentation and texture changes were observed. Histological findings showed a marked decrease in the number of junctional melanocytes and the nests in the papillary and reticular dermis. The combined laser treatment is an effective method for the treatment of giant CMN, but further study is warranted to follow-up questions of recurrence and malignant change.

Abstract
BACKGROUND Phacomatosis pigmentovascularis (PPV) consists of a capillary malformation with a variety of melanocytic lesions, which involve various regions of the body and are difficult to treat with conventional therapeutic tools. OBJECTIVE We described two cases with PPV (type IIa and IIb) that were successfully treated with different lasers. METHODS The areas involved by both melanocytic lesions and port-wine stains were treated using the Q-switched ruby laser, the Q-switched Alexandrite laser, and the flashlamp pumped pulsed-dye laser. RESULTS Removal of a good portion of cutaneous and vascular lesions using combined multiple laser approach was achieved after 6 sessions in the first case under general anesthesia and after 31 sessions under local anesthesia in the second case. CONCLUSION PPV type II can be treated successfully by laser treatment. We prefer to start combined multiple laser treatment of PPV in childhood period under general anesthesia because it will reduce the number of treatment, improve the patient's quality of life, and increase the cost-effectiveness of the treatment.

Abstract
Congenital melanocytic nevi can be cosmetically disfiguring, give rise to melanoma, and suggest the presence of neurocutaneous melanocytosis. Management decisions must be tailored for each patient and each nevus, taking into consideration the risk for developing malignancy, risk for developing symptomatic neurocutaneous melanocytosis, cosmetic implications of having the nevus, cosmetic implications of any resultant surgical scars from their removal, adverse effects that the nevus may have on psycho-social development, and the adverse effects and long-term sequelae of any surgical intervention. The advantages and disadvantages of different modalities used in the treatment of congenital melanocytic nevi are discussed. Organizational flow diagrams are presented to help clinicians in managing patients with different sized congenital melanocytic nevi.

Abstract
The effect of the normal-mode ruby laser (NMRL) and the combined (normal mode plus Q-switched) ruby laser on congenital melanocytic nevi (CMN) was evaluated, and the degree to which both laser treatment regimens remove melanocytes was compared in 15 patients. Each nevus was marked to designate half of the lesion for the NMRL treatment and half of the lesion for combined ruby laser treatment. The efficacy of each laser treatment was correlated with the degree of clinical improvement determined by photographic assessment, histological examination, and melanin reflectance spectrometry before and 3 months after laser treatment. A single treatment using the NMRL with energy fluences of both 20 J per square centimeter and 30 J per square centimeter resulted in a slight, but not significant, improvement in lightening of pigmentation (42.61% and 30.38%, respectively). A better clinical response (excellent to good) and higher percentage of lightening (64.45%-72.43%) was noted in the combined ruby laser-treated areas than the NMRL-treated areas. Histological results showed that the combined ruby laser provided a marked decrease in the number of the nevomelanocytic nests in both the junctional area and the papillary and reticular dermis, whereas the NMRL (with energy fluences of either 20 J per square centimeter or 30 J per square centimeter) caused a decrease in the junctional area and the papillary dermis. None of the nevi had complete clearance of the pigmentation after a single treatment. Therefore, multiple (four to five) treatment sessions are needed to cause complete removal of nevomelanocytic nests in CMN. In conclusion, the combined ruby laser is more effective than the NMRL alone in the treatment of CMN without scarring or textural change of the skin.

Abstract
BACKGROUND Laser surgery for Asians differs from that for Caucasians in several important respects. In Asians, some conditions such as nevus of Ota are frequently seen and certain adverse reactions, especially postinflammatory hyperpigmentation, tend to be more common. OBJECTIVE This article reviews the use of different types of lasers and intense pulsed light (IPL) sources for the treatment of Asian patients. METHODS Various cutaneous conditions amenable to laser treatment, including lentigines, nevus of Ota, acquired bilateral nevus of Ota-like macules, port-wine stains, and acne scarring, are discussed. Strategies for the management of postinflammatory hyperpigmentation are offered. RESULTS Appropriate selection and careful planning of the treatment can lead to excellent clinical outcome. CONCLUSION Lasers and intense pulsed light sources are important tools for the treatment of a wide range of cutaneous conditions in Asians.
