Background: The ALLEGRO phase IIa and IIb/III (NCT02974868 and NCT03732807) studies have demonstrated that ritlecitinib is effective and well tolerated in adults and adolescents with alopecia areata (AA) up to 48 weeks., Objectives: To assess the efficacy of ritlecitinib through month 24 and safety through data cutoff in the ALLEGRO phase IIb/III study and the ongoing long-term open-label phase III ALLEGRO-LT study (NCT04006457)., Methods: Patients aged ≥ 12 years with AA and ≥ 50% scalp hair loss from ALLEGRO IIb/III who rolled over to ALLEGRO-LT after up to 48 weeks were included. Proportions of patients with responses based on clinician-reported Severity of Alopecia Tool (SALT) scores of ≤ 20 and ≤ 10, eyebrow assessment (EBA) and eyelash assessment (ELA), patient global impression of change (PGI-C) and patient satisfaction with hair growth were reported through month 24 for patients who received ritlecitinib 50 mg daily with or without a 200-mg 4-week daily loading dose. Observed and imputed data [last observation carried forward (LOCF)] were reported up to 9 December 2022. Safety was assessed throughout., Results: At month 12, a SALT score ≤ 20 was achieved by 45.1% and 45.9% (observed) and 40.3% and 41.8% (LOCF) of the 191 and 194 patients who received ritlecitinib 50 mg and ritlecitinib 200 mg/50 mg, respectively. At month 24, these proportions increased to 60.8% and 63.1% (observed) and 46.1% and 50.8% (LOCF), respectively. Patients with abnormal EBA or ELA scores at baseline achieved responses at month 24 [EBA observed: 57.6% (50 mg), 61.0% (200/50 mg); EBA LOCF: 46.8% (50 mg), 50.9% (200/50 mg); ELA observed: 51.2% (50 mg), 62.7% (200/50 mg); ELA LOCF: 43.2% (50 mg), 51.7% (200/50 mg)]. PGI-C response was achieved by patients at month 24 [observed: 70.0% (50 mg), 76.4% (200/50 mg); LOCF: 56.6% (50 mg), 65.5% (200/50 mg)]. Safety profiles for both treatment groups were consistent with the known safety profile of ritlecitinib., Conclusions: Ritlecitinib has clinically meaningful and sustained efficacy beyond 1 year with a favourable safety and tolerability profile, supporting its long-term use in patients aged ≥ 12 years with AA., Competing Interests: Conflicts of interest: M.P. has been a consultant and/or investigator for Pfizer, Eli Lilly and Procter & Gamble.

Background: Afro-textured hair exhibits distinct physicochemical properties with possible variations in measurable hair parameters. Standardized documentation of trichoscopic norms of afro-textured hair in indigenous Africans is notably lacking., Methods: A cross-sectional study involving 122 South Africans of both genders of African ancestry (mean age 20.9 ± 3.3 years) with natural afro-textured hair was performed to establish trichoscopic norms. Standard images, one overview, and five microimages (one 20× and four 50× magnifications) were captured with the FotoFinder Medicam1000V2 videodermoscope. Hair density (HD; N/cm 2 ); hair shaft thickness (HST; μm); the proportion of thin, mid, and thick hairs (%); cumulative hair thickness (mm/cm 2 ); and follicular units (FU; N/cm 2 ) were assessed., Results: The average HD was 139.1 ± 33.88 hairs/cm 2 with significant variations across different scalp areas. The average hair thickness was 62.59 ± 8.45 μm with the frontal scalp showing the greatest HST, the proportion of thick hairs, cumulative hair thickness, and FU densities; the temporal had the greatest proportion of thin hairs, whereas the occipital showed the highest proportion of triple hair FU. Male participants exhibited significantly greater average hair thickness, more thick hairs, and more double and triple FU, whereas females had higher cumulative hair thickness density, more thin and intermediate hairs, and more single follicular units., Conclusion: Baseline trichoscopic values for natural afro-textured hair in indigenous South Africans reveal lower hair densities, variations in shaft diameters, and follicular unit patterns compared to other racial groups. Significant gender-based differences are evident in some of the measured parameters. Tailored reference values are essential for accurate clinical evaluations and hair transplant planning., (© 2025 the International Society of Dermatology.)

Background: Lichen planopilaris (LPP) is the most common form of scarring alopecia in adults. The disease may also occur in children and adolescents. The aim of this systematic review is to evaluate clinical, trichoscopic, and histopathologic features of pediatric LPP. Therapeutic management is also discussed., Methods: The systematic review was performed according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines by searching PubMed, Scopus, and EBSCO databases with the last search on June 18, 2024., Results: A total of 12 studies including 20 children were analyzed. Male predominance was observed. The typical presentation of LPP in children included scarring, perifollicular erythema, scaling, and plugging; atrophy, and follicular hyperkeratotic papules, located most commonly in the vertex. The most common trichoscopic findings were scaling and blue-gray dots, perifollicular erythema, and the absence of follicular ostia. Histopathological examination revealed perifollicular fibrosis, perifollicular interface lymphocytic inflammation, pigment incontinence, cytoid bodies, and scarring in the dermis. Complete or partial response was observed in children treated with topical, intralesional, and systemic corticosteroids, methotrexate, pioglitazone, and tocilizumab., Conclusions: LPP is a rare cause of scarring alopecia in children. The disease should be taken into consideration in the differential diagnosis of patchy hair loss in children., (© 2024 Wiley Periodicals LLC.)

Background: Lichen planus (LP) is a chronic inflammatory disease that can present with significant morbidity, particularly in children. Erosive lichen planus (ELP), its rare destructive subtype, can be particularly difficult to diagnose and manage. We present a rare pediatric case of ELP with multisite involvement and discuss the differential diagnosis. Case Presentation : A 12-year-old boy presented with painful erosions and ulcers on the lateral tongue and dystrophic nails. His six-year history of tongue and nail lesions prompted several comprehensive examinations. Laboratory tests did not reveal any abnormalities. Histopathological examination of the tongue lesions was representative of ELP. Line-field confocal optical coherence tomography (LC-OCT) examination of the tongue lesions showed features that strongly correlated with histopathology. The patient was later hospitalized due to dysphagia and esophageal food impaction, during which esophageal ELP was confirmed. The patient was initially managed with topical corticosteroids. He was later started on systemic therapy in the form of methotrexate and low-dose naltrexone to address his symptoms and disease presentation. Conclusions: This case highlights the complexities of diagnosis and management of ELP in pediatric patients. A multidisciplinary approach and regular follow-up are necessary to manage symptoms, prevent complications, and improve quality of life.

Background/Objectives : Minoxidil, in addition to its vasodilatory effect, has also immunomodulatory properties that may be partially responsible for its efficacy in alopecia areata. The aim of the study was to evaluate the efficacy of monotherapy with topical or oral minoxidil in alopecia areata. Methods : A systematic review and meta-analysis of the efficacy of monotherapy with minoxidil in alopecia areata was conducted following the PRISMA guidelines. Efficacy of minoxidil in alopecia areata was evaluated separately for three groups of the patients: (1) treated with 5% topical minoxidil, (2) less than 5% topical minoxidil, and (3) oral minoxidil. Therapeutic response was defined as any regrowth of terminal hair. Results : Of 244 articles, 13 were considered eligible for the further analysis. The study included 372 patients with alopecia areata (338 using topical minoxidil and 34 taking oral minoxidil). The mean time of treatment ranged from 2 to 60 weeks (mean: 27 weeks). The response rate for 5% topical was 82% (95% CI 0.7-0.93) and 58% (95% Cl 0.5-0.67) for the less than 5% topical minoxidil group. For the group of patients treated orally, the response rate was 82%. Conclusions : Minoxidil, both topical and oral, may be beneficial in monotherapy in patients with alopecia areata. 5% topical minoxidil is characterized by significantly higher efficacy compared to minoxidil at a lower concentration. There are no sufficient data to recommend minoxidil as a first-line therapeutic option for alopecia areata.

Frontal fibrosing alopecia (FFA) is a primary cicatricial alopecia characterized by hairline recession, pruritus, and facial papules (FP). Various therapies are used to stabilize disease activity and induce remission. However, FP of FFA is resistant to treatment in many cases. In this review, we searched the PubMed and Google Scholar databases to screen the published literature on treatment options for FP in the context of FFA. Overall, 12 studies were included in this review. Available literature suggests a noticeable improvement in resistant-to-treatment FP in FFA patients with oral isotretinoin. The available evidence is limited and is derived from retrospective studies and case reports/series. Systemic isotretinoin can be considered a promising therapeutic regimen for treating resistant-to-treatment FP of FFA patients. However, more extensive, well-designed studies are necessary for confirmatory evidence., (© 2024 the International Society of Dermatology.)

Red scalp is a common complaint that may constitute a diagnostic and therapeutic challenge in daily clinical practice. Among the numerous diseases to cause diffuse scalp erythema are psoriasis, seborrhoeic dermatitis, contact dermatitis, diffuse lichen planopilaris, dermatomyositis and scalp rosacea. Accurate diagnosis is crucial for optimal treatment outcomes. Histology most frequently discriminates the underlying condition, but it requires scalp biopsy. In many cases, the combination of clinical examination and trichoscopy is sufficient for establishing the correct diagnosis. The main trichoscopic features of psoriasis are silver-white scaling, regularly distributed dotted (glomerular) vessels or twisted red loops, and punctate haemorrhages. Yellowish-white scaling and thin arborizing vessels are typical features of seborrhoeic dermatitis. Contact dermatitis is characterized by the presence of yellow exudate and polymorphic vessels, while perifollicular scaling and erythema with the lack of follicular openings are typical findings in lichen planopilaris. In scalp dermatomyositis, tortuous and arborizing vessels with interfollicular and perifollicular pigmentation may be detected. The most characteristic features of scalp rosacea are perifollicular scaling and polygonal/arborizing vessels. This review also summarizes histological features and therapeutic options for these conditions., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (© The Author(s) 2023.

Background: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease. Due to its high prevalence, considerable morbidity, and chronicity, there is a need for the accurate in vivo evaluation of treatment efficacy. Line-field confocal optical coherence tomography (LC-OCT) is a new emerging imaging technique able to perform a non-invasive, real-time examination of the epidermis and the upper dermis. LC-OCT may represent a promising tool in the diagnosis and treatment follow-up of chronic eczematous skin diseases with barrier defects., Objectives: We aimed to investigate the role of LC-OCT in the non-invasive monitoring of the treatment effect on five patients with severe atopic dermatitis during dupilumab treatment., Materials and Methods: LC-OCT imaging was performed on five patients (three women and two men) aged between 14 and 85 years old at the baseline and at 2, 4, and 6 weeks of treatment with dupilumab. The LC-OCT scans were performed at two sites, the lesional skin in the antecubital fossa and the extensor part of the arm, considered a control site on each patient for comparison. The captured images were later evaluated. Descriptive statistics and a t -test were used to compare the analyzed parameters over time and between involved atopic skin and clinically healthy skin., Results: The LC-OCT imaging was able to detect the difference in stratum corneum (SC) thickness and quality and epidermal thickness (ET) and the changes before and after treatment with high accuracy. The main findings include a significant reduction in the epidermal and stratum corneum thickness and decreased epidermal spongiosis and inflammation, with better quality of the stratum corneum indicating restoration of its tightness at both lesional and control sites., Conclusions: This study demonstrates that clinical improvement of affected and unaffected atopic skin under dupilumab treatment correlates with the LC-OCT findings. LC-OCT represents a novel, non-invasive tool examining the in vivo skin barrier and inflammation and can help to monitor the treatment efficacy among patients with atopic dermatitis in daily practice.

Trial Design: Pemphigus is a rare but life-threatening autoimmune disease requiring long-term treatment that minimizes corticosteroid (CS) exposure while providing consistent disease control. The phase 2 pemphigus study of oral, reversible, covalent Bruton tyrosine kinase inhibitor rilzabrutinib demonstrated rapid and sustained efficacy with well-tolerated safety., Methods: Adults (aged 18-80 years) were randomized 1:1 to 400 mg rilzabrutinib (n = 65) or placebo (n = 66) twice daily (with CS ≤ 0.5 mg/kg/d) for 37 weeks in the phase 3 PEGASUS study in moderate-to-severe pemphigus vulgaris/pemphigus foliaceus., Results: The primary endpoint of complete remission from week 29 to week 37 with the amended endpoint CS dose ≤10 mg/d was not significant for 13 of 54 (24%) rilzabrutinib versus 10 of 55 (18%) placebo patients with PV (P = .45). Secondary endpoints showed numerical but nonsignificant improvements with rilzabrutinib (vs placebo) in reduced CS use, prolonged complete remission duration, and faster time to first complete remission., Conclusions: Overall, rilzabrutinib was well-tolerated, with similar adverse events reported in both groups. Using minimal CS dose ≤10 mg/d and excluding remote observations, the primary efficacy endpoint was not met. However, results from a prespecified sensitivity analysis using CS dose ≤5 mg/d, considering all observations, and including all patients support Bruton tyrosine kinase inhibition as a viable therapeutic approach for pemphigus., (Copyright © 2024 The Authors.

Introduction: Diagnosis of persistent erythematous, scaly patches, or plaques can be complex since psoriasis (Ps), eczematous dermatitis (ED), and mycosis fungoides (MF) can be considered. Dermoscopy, which is a noninvasive diagnostic tool, is commonly used to examine blood vessels, scales, and background color; however, research on hair shaft evaluation in inflammatory dermatoses remains scarce. The aim of the study was dermoscopic evaluation of hair shafts in skin lesions localized on the non-scalp skin areas in patients diagnosed with MF, Ps, and ED., Methods: This was a retrospective evaluation of 55 patients diagnosed with MF, Ps, and ED. Photographic and dermoscopic documentation of these patients and detailed medical history were evaluated., Results: A total of 21 patients with MF, 21 patients with Ps, and 13 patients with ED were evaluated. The examination revealed the presence of various abnormalities of hair shafts (e.g., numerous pili torti, single pili torti, 8-shaped hairs, pigtail hairs, broken hairs, hair shafts rapidly tapered over long sections, hair shafts irregular in thickness, angulated hairs, branched hairs, the presence of trichorrhexis nodosa, and monilethrix-like hairs), yellow dots, and black dots. The presence of pili torti was found in 80% of patients with MF, compared with 16% of patients with Ps and 8% of patients with ED (p < 0.005), with multiple pili torti found only in MF patients (67%) (p < 0.005). Statistically significant differences also applied to hair shafts rapidly tapering over long sections and 8-shaped hairs, which occurred only in MF patients (p < 0.005 and p = 0.035, respectively)., Conclusions: The presence of hair shaft abnormalities such as numerous pili torti, 8-shaped hairs, and hair shafts rapidly tapering over long sections is an important criterion that should be considered in the dermoscopic differentiation of the patchy/plaque mycosis fungoides and inflammatory dermatoses, such as psoriasis and eczematous dermatitis localized on the non-scalp skin areas., (© 2024.

Background: Onychoscopy is a noninvasive method helpful in diagnosing nail disorders. The aim of the study was to review literature on the usability of onychoscopy in nail psoriasis, nail lichen planus, and nail lichen striatus., Summary: Onychoscopic features of nail psoriasis are pitting, onycholysis with erythematous border, salmon patches, splinter hemorrhages, dotted vessels in lateral and proximal folds, and hyponychium. Onychoscopic features of nail lichen planus are onychorrhexis, onycholysis, longitudinal melanonychia, and red lunula. The literature on the usability of onychoscopy in nail lichen striatus is scarce., Keynotes: Onychoscopy facilitates evaluation of nail abnormalities compared to the clinical examination. Lunular alterations, salmon patches, erythematous border of onycholysis as well as splinter hemorrhages in nail psoriasis are better visualized with onychoscopy compared to the naked eye. Onychoscopy enhances detection of melanonychia, dyschromia, and lunular changes in nail lichen planus. Onychoscopic features are different in fingernails and toenails., Competing Interests: The authors have no conflicts of interest to declare., (© 2024 S. Karger AG, Basel.)

To date, more than 400 types of human papillomavirus (HPV) have been identified. Despite the creation of effective prophylactic vaccines against the most common genital HPVs, the viruses remain among the most prevalent pathogens found in humans. According to WHO data, they are the cause of 5% of all cancers. Even more frequent are persistent and recurrent benign lesions such as genital and common warts. HPVs are resistant to many disinfectants and relatively unsusceptible to external conditions. There is still no drug available to inhibit viral replication, and treatment is based on removing lesions or stimulating the host immune system. This paper presents the systematics of HPV and the differences in HPV structure between different genetic types, lineages, and sublineages, based on the literature and GenBank data. We also present the pathogenesis of diseases caused by HPV, with a special focus on the role played by E6, E7, and other viral proteins in the development of benign and cancerous lesions. We discuss further prospects for the treatment of HPV infections, including, among others, substances that block the entry of HPV into cells, inhibitors of viral early proteins, and some substances of plant origin that inhibit viral replication, as well as new possibilities for therapeutic vaccines.

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this consensus provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes., (© 2024 European Academy of Dermatology and Venereology.)

Background: There is limited insight into the current disease burden and everyday clinical management of moderate-to- severe AD in Poland, Czechia, Russia, and Turkiye. Therefore, this study aimed to get information-driven insights regarding the current disease burden and clinical management of patients with moderate-to-severe AD with common and differentiating aspects of the patient journey and establish a consensus., Methods: In this modified 2-round Delphi panel, 133 questions were asked in total to 27 dermatologists. A consensus was achieved when 70% of the panel members strongly agreed or agreed (or strongly disagreed or disagreed) with an item. Statements with <40% agreement dropped from the Delphi rounds and were not repeated., Results: The results state that AD has a significant impact on the quality of life for both patients and their families with social and economic consequences in these countries. While there were significant dissimilarities regarding the current treatment approach by preference order and treatment duration among participants, there was also a high percentage of consensus on literature and guideline-based statements. Current topical therapies and the immune response modifiers were not found to be sufficient by panelists to cover the therapeutic needs of patients with moderate-to-severe AD. Moreover, panelists highlighted the significant burden of adverse events with the off-label use of currently available immunosuppressants., Conclusions: These results underlined that there is a significant disease burden with an unmet treatment need for patients with moderate-to-severe AD in Poland, Czechia, Russia, and Turkiye., Competing Interests: All panel members/authors received honoraria from Pfizer for their consultancy on answering the questionnaires.
