ABSTRACT
BACKGROUND: Systemic Janus kinase inhibitors (JAKi) and dupilumab both have emerged as promising therapeutics for atopic dermatitis (AD). While dupilumab has a favorable safety profile, use of oral JAKi has been established in other diseases that carry potential comorbid susceptibilities that influence safety. OBJECTIVE: To provide real-world evidence of the safety of oral JAKi in AD patients. METHODS: The study used observational data from TriNetX (Cambridge, Massachusetts). Patients with AD treated with either oral JAKi (upadacitinib, abrocitinib, and baricitinib) or dupilumab were enrolled. The two treatment groups were propensity-score matched 1:1 based on demographics, comorbidities, and prior medications. Safety outcomes within two years after the initiation of medications were measured by hazard ratios with 95% confidence intervals. RESULTS: A total of 14,716 patients were included, with 942 patients treated with oral JAKi and 13,774 with dupilumab. The two treatment groups included 938 patients after matching. Treatment with oral JAKi was not associated with increased risks of mortality, malignancies, major adverse cardiovascular events, venous thromboembolism, renal events, or serious gastrointestinal events. However, patients receiving oral JAKi showed significantly higher risks of skin and subcutaneous tissue infection, herpes infection, acne, cytopenia, and hyperlipidemia, whereas the risk of ophthalmic complications was higher in those receiving dupilumab. CONCLUSION: This study found that oral JAKi did not exhibit concerning safety issues in treating patients with AD but increased the risk of infections and laboratory abnormalities. Long-term follow-up data are required to validate these findings.
ABSTRACT
Dermoscopy aids in the diagnosis and management of pigmented growths and disorders of pigmentation in children. However, there is limited literature on the dermoscopic appearance of café-au-lait macules (CALMs) and congenital melanocytic nevi in patients with dark skin. We report two cases of young children with dark skin and many hyperpigmented patches in whom dermoscopy was utilized to accurately diagnose CALMs and facilitate testing for neurofibromatosis.
ABSTRACT
Cutaneous BAP1-inactivated melanocytomas (BIM) are melanocytic proliferations defined histopathologically by an epithelioid, predominantly dermal melanocytic proliferation with loss of BAP1, and have been largely characterized in adult patients but less well-described in pediatric cohorts. BIM share overlapping histological features with those seen in Spitz nevi; however, unlike Spitz nevi, the majority of BIM carry both BAP1 and BRAFV600E mutations. This study investigated the potential overlap of BIMs with pediatric Spitz nevi by performing immunohistochemical staining of BAP1 and BRAFV600E on pediatric melanocytic tumors with banal Spitz and dermal features. None of the stained tumors in our study exhibited the concurrent BAP1 loss and BRAFV600E positivity that are characteristic of adult BIM, suggesting that this is a low-frequency mutation among banal tumors in the pediatric population.

BACKGROUND: Pediatric longitudinal melanonychia (LM) can exhibit atypical features that mimic red-flag signs for subungual melanoma in adults and lead to diagnostic uncertainty. Nail biopsy may be unnecessary if clinical inspection and dermoscopy suggest a benign nature. METHODS: We searched PubMed and Embase from inception to February 2023 for studies of any design reporting either the number or proportion of clinical and dermoscopic features in at least five children (≤18 years) with LM. Non-English articles, reviews, and abstracts were excluded. We performed a systematic review and meta-analysis to collate all existing data. RESULTS: A total of 1218 articles were screened and 24 studies with 1391 pediatric patients were included. Nevus was the most common diagnosis (86.3%). The most prevalent sites were fingernails (76.2%) and first digits (45.4%). Pooled proportions of common features were: dark-color bands (69.8%), multi-colored bands (47.6%), broad bandwidth (41.1%), pseudo-Hutchinson sign (41.0%), irregular patterns (38.1%), Hutchinson sign (23.7%), dots and globules (22.5%), nail dystrophy (18.2%), and triangular sign (10.9%). Outcomes included progression (widening or darkening, 29.9%), stability (23.3%), and spontaneous regression (narrowing or fading, 19.9%). Only eight cases of subungual melanoma in situ were reported, and no invasive melanomas were identified. CONCLUSION: Although atypical characteristics are common in pediatric LM, the probability of malignant transformation is exceedingly low. Appropriate evaluation and management of pediatric LM includes careful clinical and dermoscopic inspection with attention to benign features followed by long-term interval follow-up.

Congenital melanocytic nevi (CMN) carry an increased risk of melanoma and may be disfiguring, and consensus regarding treatment recommendations is lacking. While clinical monitoring is the standard of care, many caregivers are interested in its removal to prevent psychosocial burden or to decrease risk. Although melanoma can occur regardless of CMN removal, there are a variety of treatments that may offer improved cosmesis or local symptom control, including surgical excision, laser therapy, and other superficially destructive techniques. Regardless of the selected management, these patients are monitored for ongoing melanoma risk. An extensive discussion with families regarding the risks and benefits of observation versus active intervention is essential. To facilitate these discussions, we herein summarize current CMN management strategies and considerations.
ABSTRACT
BACKGROUND: Pediatric melanoma presents with distinct clinical features compared to adult disease. OBJECTIVE: Characterize risk factors and negative outcomes in pediatric melanoma. METHODS: Multicenter retrospective study of patients under 20 years diagnosed with melanoma between January 1, 1995 and June 30, 2015 from 11 academic medical centers. RESULTS: Melanoma was diagnosed in 317 patients, 73% of whom were diagnosed in adolescence (age ≥11). Spitzoid (31%) and superficial spreading (26%) subtypes were most common and 11% of cases arose from congenital nevi. Sentinel lymph node biopsy was performed in 68% of cases and positive in 46%. Fatality was observed in 7% of cases. Adolescent patients with melanoma were more likely to have family history of melanoma (P = .046) compared to controls. LIMITATIONS: Retrospective nature, cohort size, control selection, and potential referral bias. CONCLUSION: Pediatric melanoma has diverse clinical presentations. Better understanding of these cases and outcomes may facilitate improved risk stratification of pediatric melanoma.

Pediatric melanoma of the scalp has the highest mortality of any anatomic location. We describe five pediatric patients with a diagnosis of scalp melanoma receiving care at Massachusetts General Hospital and/or Boston Children's Hospital from 2018 through 2022. Melanoma presented in diverse contexts: cellular blue nevus-associated, compound nevus-associated, spitzoid, nodular, and superficial spreading subtypes. This study describes a range of melanoma presentations and emphasizes the need for additional compilation of data on pediatric scalp melanomas to promote their recognition and improve patient care.

Importance: Therapy for advanced melanoma has transformed during the past decade, but early detection and prognostic assessment of cutaneous melanoma (CM) remain paramount goals. Best practices for screening and use of pigmented lesion evaluation tools and gene expression profile (GEP) testing in CM remain to be defined. Objective: To provide consensus recommendations on optimal screening practices and prebiopsy diagnostic, postbiopsy diagnostic, and prognostic assessment of CM. Evidence Review: Case scenarios were interrogated using a modified Delphi consensus method. Melanoma panelists (n = 60) were invited to vote on hypothetical scenarios via an emailed survey (n = 42), which was followed by a consensus conference (n = 51) that reviewed the literature and the rationale for survey answers. Panelists participated in a follow-up survey for final recommendations on the scenarios (n = 45). Findings: The panelists reached consensus (≥70% agreement) in supporting a risk-stratified approach to melanoma screening in clinical settings and public screening events, screening personnel recommendations (self/partner, primary care provider, general dermatologist, and pigmented lesion expert), screening intervals, and acceptable appointment wait times. Participants also reached consensus that visual and dermoscopic examination are sufficient for evaluation and follow-up of melanocytic skin lesions deemed innocuous. The panelists reached consensus on interpreting reflectance confocal microscopy and some but not all results from epidermal tape stripping, but they did not reach consensus on use of certain pigmented lesion evaluation tools, such as electrical impedance spectroscopy. Regarding GEP scores, the panelists reached consensus that a low-risk prognostic GEP score should not outweigh concerning histologic features when selecting patients to undergo sentinel lymph node biopsy but did not reach consensus on imaging recommendations in the setting of a high-risk prognostic GEP score and low-risk histology and/or negative nodal status. Conclusions and Relevance: For this consensus statement, panelists reached consensus on aspects of a risk-stratified approach to melanoma screening and follow-up as well as use of visual examination and dermoscopy. These findings support a practical approach to diagnosing and evaluating CM. Panelists did not reach consensus on a clearly defined role for GEP testing in clinical decision-making, citing the need for additional studies to establish the clinical use of existing GEP assays.

Acne fulminans (AF) is an uncommon variant of inflammatory acne with abrupt eruption of painful nodules, pustules, and hemorrhagic ulcerations, often associated with systemic symptoms. Paradoxical adverse reactions to tumor necrosis (TNF)-alpha inhibitors have been reported, and rare cutaneous complications include pyoderma gangrenosum, Sweet syndrome-like hypersensitivity eruptions, and pustular folliculitis. We report an unusual case of AF in a patient with Crohn disease that worsened with doses of adalimumab, which is considered a second-line treatment for AF. This case highlights that acneiform eruptions may be an underreported paradoxical adverse reaction to anti-TNF alpha therapy.

Cutis verticis gyrata (CVG), characterized by cerebriform overgrowth of the scalp, is rarely observed in congenital melanocytic nevi (CMN). We describe a 13-year-old male with autism and a large CMN of the scalp with numerous satellite nevi whose scalp nevus exhibited evolution with poliosis and CVG. Given the potential association of CVG (independent of CMN) with seizures, neuropsychiatric, and ophthalmologic disorders, and nevus-associated CVG (cerebriform intradermal nevus) with melanoma, multidisciplinary evaluation of CMN patients with CVG is important to guide management and treatment.

The diagnostic trends of Gorlin syndrome (GS) in the pediatric population are not well understood. In an international survey conducted by the Gorlin Syndrome Alliance, 118 individuals who were diagnosed with GS when aged 18 years and under provided information about their diagnosis. Oral surgeons and dermatologists were the most commonly reported physicians involved in diagnosis for 48.3% and 28% of cases, respectively. For 50% of children, the diagnosis was made within a year from presenting sign(s), while 27% report over 4 years to receive GS diagnosis. Of individuals who reported >4 years between presenting signs and diagnosis, 81.3% attributed the delay to insufficient medical team knowledge and 65.6% attributed to lack of personal awareness that presenting signs were related to GS, emphasizing the need for patient and physician education of GS for prompt diagnosis.
