Our aim was to characterize patient-reported factors beyond scalp hair loss that contribute to AA severity while modifying for socioeconomic factors.Methods: Patients with AA were recruited to take a survey. Multivariable linear regression was performed to evaluate lifetime AA severity while adjusting for socioeconomic variables, current AA severity at the time of survey, and patient-reported disease burden.Results: Patient-reported AA severity was associated with scalp hair loss (OR: 4.19, 95% CI: [1.35-13], p = 0.013), facial hair loss (OR: 3.55, 95% CI: [1.75-7.21], p < 0.001), increased financial burden (OR: 2.41, 95% CI: [1.21-4.8], p = 0.013), and greater emotional burden (OR: 2.96, 95% CI: [1.48-5.93], p = 0.002), while presence of comorbidities were linked to less severe AA (OR: 0.38, 95% CI: [0.17-0.84], p = 0.017).Conclusion: Survey population was homogeneous and may not reflect the general community with AA. Self-reported data may introduce recency or recall bias. Scalp and facial hair loss, along with emotional and financial burdens, correlate with increased patient-reported AA severity. This suggests factors beyond scalp hair loss should be considered when assessing AA severity.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":" ","pages":"1-6"},"PeriodicalIF":1.4,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12105852/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144162374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it predominantly presents before the age of 40, AA can occur at any age and is strongly associated with genetic predisposition. Environmental, hormonal, and psychological factors have been implicated in disease onset and progression. Recent evidence highlights the immunomodulatory role of vitamin D, traditionally recognized for its functions in bone metabolism and calcium homeostasis, in skin health and immune regulation, raising interest in its potential relevance to AA pathogenesis and treatment.Summary: This review examines the epidemiology, genetic predisposition, and immunological mechanisms underlying AA, emphasizing the loss of immune privilege in hair follicles as a key pathogenic event. Additionally, it examines the role of vitamin D and its receptor (VDR) in hair follicle homeostasis, discussing the association between vitamin D deficiency, altered VDR expression, and disease severity. Emerging clinical data suggest that vitamin D supplementation and analogs, such as calcipotriol, may serve as adjunctive therapeutic strategies, with potential benefits in mitigating disease severity and reducing relapse rates.Key messages: (1) Vitamin D serves as a critical immunomodulator in AA, regulating follicular immune privilege and key inflammatory pathways involved in disease pathogenesis. (2) Vitamin D deficiency is frequently observed in patients with AA and has been associated with increased disease severity, prolonged duration, and a higher risk of relapse. (3) Emerging evidence supports the therapeutic potential of vitamin D analogs and supplementation in AA, positioning vitamin D as a promising adjunct or primary treatment modality.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":" ","pages":"1-11"},"PeriodicalIF":1.4,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12105854/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unemployment, history of major stressful events, thyroid disorder, history of hair dyeing, using face soaps, taking supplements, postmenopausal status, and family history of LPP or other types of alopecia had significant relationship with LPP (all p values <0.05).Conclusion: LPP has associations with environmental and non-environmental risk factors and, also, genetic component.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"11 2","pages":"159-165"},"PeriodicalIF":1.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11961126/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143773480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scalp is involved in up to 60% of patients due to the high concentration of antigens in hair follicles. Trichoscopy has been studied in bullous diseases. However, research on pemphigus trichoscopy remains scarce. This study aimed to analyze the main trichoscopic features of pemphigus on the black scalp, a topic poorly appraised thus far.Methods: Ten male and 8 female patients were enrolled, evenly distributed between PV (aged 16-59) and PF (aged 20-72), with Fitzpatrick phototypes equal to or greater than IV. Scalp evaluations were conducted using digital dermoscopy, with 20-to-70-fold magnification. Our results were compared with original research on Caucasian scalp pemphigus.Results: Our study identified the previously published and also novel trichoscopic features. Our patients exhibited higher percentages (p < 0.05) of eight classic structures, considering both PF and PV; PF only; PV only. Aside from yellow dots (p = 0.002), our sample showed no statistically significant differences between the PV and PF groups in black patients.Conclusion: Peculiarities of black scalp trichoscopy did not interfere in the diagnosis of pemphigus. Trichoscopy should be a routine diagnostic tool in patients with bullous scalp diseases, especially in the early stages, and to guide biopsy. To our knowledge, this is the first study focused on trichoscopy of pemphigus affecting black scalp. It indicates that, among other findings, yellow dots may be a relevant hallmark of scalp PV.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"11 2","pages":"147-150"},"PeriodicalIF":1.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11961084/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143773164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After trichoscopy, skin scraping from the patients was taken for direct mycological examination with 10% KOH and cultures in Sabouraud and Mycosel media; patients with positive cultures for M. canis and T. tonsurans were selected. The association between the trichoscopic and etiological findings of Tc was statistically evaluated using Fisher's exact test.Results: Some trichoscopy findings, such as perifollicular desquamation and broken hair, were nonspecific to determine the Tc agent. The presence of Morse code (barcode-like) whitish sheath was more common in M. canis infection, even in the small number of patients of our sample.
