Abstract
Becker's nevus (BN) is a benign hamartoma that may present as a distressing cosmetic problem. The treatment of BN poses a significant challenge as current therapeutic modalities are suboptimal and have an increased risk of adverse effects, such as scarring and dyspigmentation. We present the use of non-ablative fractional laser therapy combined with Q-switched Nd:YAG laser as a possible therapeutic option for BN treatment and review relevant literature to discuss its efficacy and limitations.

Evaluating the Roles of Different Types of Laser Therapy in Becker’s Nevus Treatment. J Clin Med 2022; 11:jcm11144230. [PMID: 35887993 PMCID: PMC9324390 DOI: 10.3390/jcm11144230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/17/2022] [Accepted: 07/18/2022] [Indexed: 02/04/2023] Open
Abstract
Becker’s nevus (BN) is a cutaneous hamartoma of benign nature that develops through adolescence and affects mostly young men. The nevus is usually located unilaterally and is characterized by hypertrichosis and hyperpigmentation. Despite recent advances in treatment modalities, no effective treatment has been established for BN hyperpigmentation. We sought to assess the efficacy and safety of fractional Erbium: YAG 2940 nm and Q-switched Nd: YAG 1064 nm lasers in the treatment of BN hyperpigmentation. Twenty-three patients with BN were included in a prospective, randomized-controlled, observer-blinded, split-lesion comparative technique trial. In each patient, two similar square test regions were randomized to either be treated with a fractional Erbium: YAG 2940 nm laser or with a Q-switched Nd: YAG 1064 nm laser. Each patient was treated with three sessions at six-week intervals. At the follow-up, clearance of hyperpigmentation was assessed by physician global assessment, visual analogue scale, grade of improvement, patient global assessment, and patient satisfaction. Regions treated with the fractional Erbium: YAG 2940 nm laser demonstrated significantly better improvement compared to ones treated with the Q-switched Nd: YAG 1064 nm (p-value = 0.001) laser. Adverse effects such as repigmentation and hypertrophic scarring were not reported during the follow-up period. The outcomes were cosmetically acceptable with overall high satisfaction among the included patients. Our data suggest a superior role for the fractional Erbium: YAG (2940 nm) laser in the treatment of BN hyperpigmentation compared to the Q-switched Nd: YAG (1064 nm) laser, along with being a safer method and having no reported side effects.

Abstract
BACKGROUND Becker's nevus syndrome is a syndrome characterized by the presence of a Becker's nevus with ipsilateral breast hypoplasia or hypoplastic defects of the muscle, skin, or skeleton. The nevus usually consists of a circumscribed, unilateral, irregularly shaped hyperpigmented macule, commonly occurring around the anterior upper trunk, with/without hypertrichosis and/or acneiform lesions. This rare syndrome has not been reported in our locality to the best of our knowledge. CASE PRESENTATION We report the case of a 15-year-old Igbo female patient who presented to our pediatric endocrinology clinic, University of Nigeria Teaching Hospital, Enugu, with complaints of asymmetry of the breasts and hyperpigmented macules on the side. Based on her symptoms, diagnosis of Becker's nevus syndrome was made. The diagnosis of Becker's nevus syndrome is mostly clinical, based on the presence of a Becker's nevus with ipsilateral breast hypoplasia or hypoplastic defects of the muscle, skin, or skeleton. In our patient, there was a Becker's nevus with ipsilateral breast hypoplasia. This syndrome, belonging to the class of epidermal nevus syndromes, is very rare, and is usually benign. She was placed on spironolactone tablets 50 mg daily, which have been associated with an improvement in the size of the hypoplastic breast, and her fears were allayed. CONCLUSION This syndrome has not been reported in our locality to the best of our knowledge and, therefore, has a propensity for misdiagnosis by clinicians because of its rarity. We therefore report this to create awareness among clinicians regarding this condition that is associated with much psychosocial trauma among patients, and that can be easily managed with oral spironolactone.

Abstract
BACKGROUND Becker's nevus is a common skin disorder. Lasers and light instruments are the major modalities for the treatment of Becker's nevus, but the outcomes were mixed. OBJECTIVE To evaluate the efficacy of the intense pulsed light for Becker's nevus in a large Chinese cohort. METHODS We retrospectively analyzed the efficacy of the intense pulsed light for Becker's nevus in a single center. RESULTS A total of 45 patients, including 26 males and 19 females (male to female ratio = 1.4), aged 5-42 years, were included in this analysis. Twenty-seven patients (60%) were with hypertrichosis. Treatments with intense pulsed light resulted in over 75% improvements in pigmentation and hair density in 1 and 2 cases, respectively. One patient displayed 51%-75% reductions in hair density. The rest displayed ≤50% improvements in pigmentation and hair density. Recurrence occurred in all cases within 6 months after the last treatment. Adverse reactions were temporary and mild hypopigmentation, hyperpigmentation, hypertrophic scar, pain, and erythema. CONCLUSION Intense pulsed light does not exhibit long-term benefits for Becker's nevus. Further studies in the large cohort are still required to validate the present results. Moreover, whether changes in the treatment parameters can improve the efficacy of intense pulsed light remains to be explored.

Abstract
Becker's nevus is a common pigmented dermatosis, usually featured by ipsilateral pigmented patch with hypertrichosis. Becker's nevus is often treated with various types of lasers although other regimens are available. However, clinical outcomes appear inconsistent among studies. To summarize the clinical outcomes of Becker's nevus treated with lasers via literature review. A variety of lasers had been used alone or in combination to treat Becker's nevus. Laser wavelengths used for Becker's nevus ranged from 504 to 10,600 nm, while the number of treatment varied from 1 to 12 sessions. The clinical outcomes were mixed although combination of lasers with different wavelengths appeared to achieve a better efficacy. Adverse effects were usually mild to moderate erythema. While lasers are relatively safe, their efficacy for Becker's nevus is moderate. It seems that combination therapy could improve the outcome. However, trials in larger group of patients are required to validate the efficacy of each type of lasers for Becker's nevus.
