RESUMO
Keratosis pilaris atrophicans faciei (KPAF) and frontal fibrosing alopecia (FFA) present diagnostic challenges due to their similar clinical characteristics. Dermatologists often employ overlapping treatment regimens, which may hinder accurate diagnosis and treatment expectations. Genetic testing offers promise for precise diagnosis and tailored treatment strategies, yet its utility in these conditions remains underexplored. This manuscript presents a unique case study of a 36-year-old male with symptoms of both KPAF and FFA, who underwent genetic testing. Despite testing negative for this mutation, the case underscores the potential of genetic testing to enhance diagnostic accuracy and optimize treatment outcomes.
RESUMO
This cohort study describes the clinical features, patient characteristics, and treatment of anti-melanoma differentiationassociated gene 5 (MDA5) dermatomyositis.

Importance: Janus kinase (JAK) inhibitors are an effective treatment option for patients with certain skin-related conditions, such as atopic dermatitis, alopecia areata, and vitiligo, but there is a current US Food and Drug Administration (FDA) boxed warning label for oral and topical JAK inhibitors regarding increased risk of major adverse cardiovascular events (MACE), venous thromboembolism (VTE), serious infections, malignant neoplasm, and death. However, this boxed warning was precipitated by results of the Oral Rheumatoid Arthritis Trial (ORAL) Surveillance study, which only included patients with rheumatoid arthritis, and the same association may not be observed in dermatologic conditions. Objective: To determine the risk of all-cause mortality, MACE, and VTE with JAK inhibitors in patients with dermatologic conditions. Data Sources: PubMed and ClinicalTrials.gov were searched from database inception to April 1, 2023. Study Selection: This review included phase 3 randomized clinical trials with a placebo/active comparator group of JAK inhibitors used for a dermatologic indication with FDA approval or pending approval or with European Union or Japanese approval. Studies without a comparison group, case reports, observational studies, and review articles were excluded. Data Extraction and Synthesis: This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Adverse events using odds ratios (ORs) and 95% CIs were calculated using a random-effects model and the DerSimonian-Laird method. Studies were screened, data abstracted, and quality assessed by 2 independent authors. The protocol was prospectively registered with PROSPERO. Main Outcomes and Measures: Primary outcomes were a composite of adjudicated MACE and all-cause mortality, and VTE. Results: The analysis included 35 randomized clinical trials with 20â¯651 patients (mean [SD] age, 38.5 [10.1] years; male, 54%) and a mean (SD) follow-up time of 4.9 (2.68) months. Findings did not show a significant difference between JAK inhibitors and placebo/active comparator in composite MACE and all-cause mortality (OR, 0.83; 95% CI, 0.44-1.57) or VTE (OR, 0.52; 95% CI, 0.26-1.04). Conclusions and Relevance: In this systematic review and meta-analysis, use of JAK inhibitors was not associated with increased risk of all-cause mortality, MACE, and VTE compared to the placebo/active comparator groups. Additional trials with long-term follow-up are needed to better understand the safety risks of JAK inhibitors used for dermatologic indications.

Alopecia is one of the most common dermatologic conditions affecting black patients, with a significantly negative impact on quality of life.1,2 Timely and accurate diagnosis is therefore critical in order to reverse or halt progression of disease.3 Unfortunately, lack of representation of skin of color (SOC) patients in the current literature may contribute to misdiagnosis as providers may be unfamiliar with the clinical spectrum of alopecia presenting in darker scalps.4 Some scarring alopecia subtypes such as Central Centrifugal Cicatricial Alopecia (CCCA) are more prevalent in certain racial groups. However, focusing solely on patient demographics and gross clinical findings may obscure accurate diagnoses. To distinguish alopecia findings in Black patients, a dedicated approach using a combination of clinical exam findings and patient history, along with trichoscopy and biopsy, is essential to prevent misdiagnosis and improve clinical and diagnostic outcomes. We present three cases of alopecia in patients of color which the initial suspected clinical diagnosis did not correspond with trichoscopic and biopsy results. We challenge clinicians to reexamine their biases and fully evaluate patients of color with alopecia. An examination should include a thorough history, clinical examination, trichoscopy, and potentially a biopsy, particularly when findings do not correlate. Our cases highlight the challenges and disparities that exist in diagnosis of alopecia in Black patients. We emphasize the need for continued research regarding alopecia in skin of color and the importance of a complete workup for alopecia to improve diagnostic outcomes.Balazic E, Axler E, Nwankwo C, et al.

BACKGROUND: Mesotherapy, a technique of transdermal microinjections of specific preparations, is increasingly used in fields such as dermatology and specifically for alopecia treatment. Its popularity stems from its ability to deliver drugs in a targeted manner while minimizing systemic side effects. OBJECTIVE: To assess and review current knowledge regarding the use of mesotherapy to deliver alopecia medications and highlight future directions for research. MATERIALS AND METHODS: The authors used research databases including PubMed and Google Scholar to identify current literature on mesotherapy and alopecia. The following search terms were used among other terms: "Mesotherapy" or "Intradermal" AND "Alopecia". RESULTS: Recent studies are promising for the intradermal delivery of dutasteride and minoxidil in the treatment of androgenetic alopecia. CONCLUSION: Although limitations exist with dutasteride and minoxidil therapies, further research regarding the preparation, delivery, and maintenance of these drugs is warranted as mesotherapy could establish this technique as a safe, effective, and viable treatment option for androgenetic alopecia.

Lichen planopilaris (LPP) is a cicatricial alopecia that presents with patchy or diffuse hair loss at the vertex or parietal scalp. The literature has limited evidence on treatments for this challenging disease, with most reports involving small groups of patients with varied or suboptimal clinical responses. Amongst individuals who do respond to therapy and eventually achieve disease remission, hair regrowth within scarred alopecic patches is rare.1 Herein, we report a patient with biopsy confirmed LPP who demonstrated remarkable hair regrowth at a previously scarred alopecic patch after initiating low-dose naltrexone (LDN) and platelet-rich plasma (PRP), despite minimal response to 4 months of prior therapy with intralesional corticosteroids, topical clobetasol, topical minoxidil, finasteride, doxycycline, and ketoconazole shampoo. This case highlights the importance of remaining flexible and diligent in therapeutic approaches to LPP and the need for more robust literature on prognosis and treatment options for LPP patients.

ABSTRACT: Papillary dermal elastolysis has been described in the setting of experimental combination nivolumab and cabiralizumab immunotherapy. We report a third patient with distinctive, generalized atrophic macules that developed after a morbilliform eruption during a clinical trial for treatment of metastatic pancreatic adenocarcinoma. Histopathological findings demonstrated diminished elastic fibers in the papillary dermis, associated with a histiocyte-rich infiltrate and increased dermal mucin, features that should clue the dermatopathologist to this condition.

BACKGROUND: Psoriasis is associated with increased cardiovascular risk that is not captured by traditional proinflammatory biomarkers. OBJECTIVE: To investigate the relationship between Psoriasis Area and Severity Index, circulating proinflammatory biomarkers, and vascular health in psoriasis. METHODS: In patients with psoriasis and in age and sex-matched controls, 273 proteins were analyzed with the Proseek Multiplex Cardiovascular disease reagents kit and Inflammatory reagents kit (Olink Bioscience), whereas vascular endothelial inflammation and health were measured via direct transcriptomic analysis of brachial vein endothelial cells. RESULTS: In psoriasis, chemokine ligand 20 (CCL20), interleukin (IL) 6, and IL-17A were the top 3 circulating proinflammatory cytokines. Vascular endothelial inflammation correlated with CCL20 (r = 0.55; P < .001) and less so with IL-6 (r = 0.36; P = .04) and IL-17A (r = 0.29; P = .12). After adjustment for potential confounders, the association between CCL20 and vascular endothelial inflammation remained significant (ß = 1.71; P = .02). In nested models, CCL20 added value (χ2 = 79.22; P < .001) to a model already incorporating the Psoriasis Area and Severity Index, Framingham risk, high-sensitivity C-reactive protein, Il-17A, and IL-6 (χ2 = 48.18; P < .001) in predicting vascular endothelial inflammation. LIMITATIONS: Our study was observational and did not allow for causal inference in the relationship between CCL20 and cardiovascular risk. CONCLUSION: We demonstrate that CCL20 expression has a strong association with vascular endothelial inflammation, reflects systemic inflammation, and may serve as a potential biomarker of impaired vascular health in psoriasis.
