Of note, immunotherapy has substantially improved survival outcomes, even in advanced stages. Nevertheless, reliable biomarkers for early relapse detection, risk stratification, and treatment monitoring remain an unmet clinical need. Conventional surveillance tools, including imaging, lactate dehydrogenase (LDH), and S100B, are limited by their sensitivity and specificity, particularly in patients with low tumor burden. The use of liquid biopsy, the analysis of body fluids such as blood, with its wide range of analytes and highly sensitive analysis methods, may represent a novel strategy to overcome the limitations of conventional biomarkers. In particular, the analysis of circulating cell-free nucleic acids from the tumor released to the blood, referred to as circulating tumor DNA (ctDNA), has emerged as a minimally invasive approach capable of capturing tumor-derived molecular information from plasma in solid tumors. ctDNA holds promise as a tool for the detection of minimal residual disease (MRD), early relapse, clonal evolution, and actionable genomic alterations. Technological advances have expanded ctDNA applications from single-mutation assays to comprehensive personalized NGS strategies and multi-modal approaches incorporating methylation profiling and fragmentomics. Clinical studies increasingly demonstrate that ctDNA detection and ctDNA dynamics provide prognostic and potentially predictive information across both (neo)adjuvant and advanced melanoma settings. In this review, we summarize the current methodological approaches and clinical evidence supporting ctDNA as a biomarker for prognosis, risk stratification, and therapy monitoring in melanoma.</p></div>","PeriodicalId":7706,"journal":{"name":"American Journal of Clinical Dermatology","volume":"27 5","pages":"977 - 995"},"PeriodicalIF":11.4,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40257-026-01056-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148381471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing evidence indicates that head and neck atopic dermatitis is not merely a regional extension of generalized disease, but a distinct phenotype shaped by the convergence of regional barrier fragility, a lipid-rich sebaceous microenvironment, microbiome imbalance, particularly involving <i>Malassezia</i> species, and a mixed immune signature integrating type 2, type 17, and type 22 inflammatory pathways. These factors promote persistent inflammation, psoriasiform features, and relative treatment refractoriness in the head and neck region. The clinical relevance of this phenotype has increased in the era of targeted therapies, as persistent or de novo facial involvement has been reported during biologic treatment, most notably with interleukin-4Rα blockade. Dupilumab-associated head and neck dermatitis exemplifies a pathway shift characterized by suppression of type 2 inflammation alongside exaggerated interleukin-22 and aryl hydrocarbon receptor-driven epithelial stress responses, providing mechanistic insight into paradoxical inflammation and incomplete regional control. Advances in immunobiology are beginning to translate into more tailored therapeutic strategies. Interleukin-13-selective biologics, systemic and topical Janus kinase inhibitors, and emerging agents targeting tissue-resident memory T-cell pathways offer new opportunities to address the dominant inflammatory circuits active in this region. Although comparative data remain limited, these approaches raise the possibility of improved control in selected patients with difficult-to-treat head and neck involvement.

Obesity and metabolic dysfunction are highly prevalent in HS, contributing to disease severity. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), widely used in type 2 diabetes and obesity, have shown additional anti-inflammatory properties that may be relevant in HS.However, data on their clinical benefit remain limited.</p><h3>Methods</h3><p>We performed a systematic review of PubMed/MEDLINE, Scopus, Web of Science, and Embase through June 2025, following PRISMA guidelines. Studies reporting outcomes in HS patients treated with GLP-1RAs were included. Information on clinical severity, quality of life, metabolism, inflammatory markers, and healthcare use were extracted.

A narrative review of the literature was conducted from January 2010 to October 2025 using terms related to photoprotection, sunscreen innovation, visible light, oral photoprotection, microbiome interaction, climate change, and personalized approaches. Articles in English and Spanish were selected based on scientific relevance. Advances in photoprotection include the development of new topical filters targeting UVA1 and visible light, as well as the incorporation of iron oxides and, in some formulations, pigmentary titanium dioxide in tinted sunscreens to enhance protection against visible light. In addition, the use of antioxidants and DNA repair enzymes has been explored to mitigate oxidative stress and address field cancerization. Natural and eco-friendly bioactive ingredients derived from botanical and marine sources show growing potential as photoprotective agents. Additional considerations such as the role of skin microbiome, and personalized photoprotection strategies tailored to skin phototype, lifestyle, diseases, and high-exposure conditions further refine preventive practice. Photoprotection is evolving into a multidimensional approach that integrates advanced topical formulations, oral agents, and individualized recommendations.

Up to 85% of patients with Fitzpatrick phototypes IV–VI develop post-inflammatory hyperpigmentation following inflammatory acne lesions. Acne-induced hyperpigmentation (AIH) results from increased melanin production and deposition triggered by inflammatory mediators, while acne-induced macular erythema reflects vascular alterations. Both AIH and acne-induced macular erythema can persist for months or even years, significantly contributing to the psychosocial burden of acne and negatively impacting patients’ quality of life — sometimes to a greater extent than active acne itself. Female individuals, darker skin color, severe acne, facial sites, excessive sunlight exposure, and traumatized lesions are important risk factors for AIH. Diagnosis relies on visual inspection, acne history, and skin phototype assessment. Treatment options include topical agents such as azelaic acid, retinoids, antioxidants, and hydroquinone, as well as systemic therapies such as isotretinoin, oral antibiotics, and oral tranexamic acid.
