This article highlights the importance of an algorithmic approach to manage multiple opportunistic infections in HIV-infected patients due to the risk of drug interactions and complications, but reports no new clinical results.

Histopathology is crucial for accurately diagnosing eruptive vellus hair cysts.

This study suggests that dermal Vδ1+ T-cells in human skin can promote alopecia areata by interacting with stressed hair follicles, potentially providing a target for new treatments.

This study found that mutant cells in hair follicles can be tolerated or eliminated by surrounding normal tissue, suggesting the potential for wild-type cells to counteract oncogenic mutations.

This study found that notch1 signaling is severely impaired in hidradenitis suppurativa patients with or without NCSTN or other gamma-secretase gene mutations, highlighting a canonical defect at the lesional tissue level.

In this study, researchers observed that oncogenic HrasG12V in single murine epidermal cells leads to an initial increase in progenitor cell renewal, but ultimately results in balanced cell fate choices that limit clone growth.

This study reports a case of GGCX syndrome in a 55-year-old Japanese male, characterized by PXE-like symptoms and coagulation deficiency, with an unreported phenotype of possible spinocerebellar degeneration.

This case report describes a young adult female with late-stage Vogt-Koyanagi-Harada disease featuring panuveitis, retinal detachment, hearing loss, alopecia, and vitiligo, who was successfully treated in a hospital.

This study found that in hidradenitis suppurativa, the proteins SERPINB3/B4 and S100A7/A8/A9 were significantly overexpressed in lesional skin compared to nonlesional skin, suggesting new pathways in the disease's pathogenesis.

In this study, eight patients with hereditary vitamin D-resistant rickets who share a specific VDR mutation showed improved clinical symptoms except alopecia after up to 11 years of treatment.

This report describes two cases of VKH disease and SO where severe alopecia, likely due to incomplete treatment, improved following systemic steroid therapy.

This study reported a case of hereditary vitamin D–resistant rickets caused by a single heterozygous missense mutation in the VDR gene, showing dominant-negative effects and reduced response to 1,25-dihydroxyvitamin D3.

This study found that the HS III element in the K14 gene's regulatory sequence promotes gene expression in inner root sheath keratinocytes, highlighting cooperative interactions in keratinocyte-specific gene regulation.

This study found that in psoriasis patients, the K17 protein probably functions as an autoantigen, with the HLA-Cw*06:02 risk genotype strongly linked to the T cell response size.

This study suggests that the NCSTN knockout mouse could serve as an HS animal model, with tamoxifen potentially used for gene deletion in mice.

This article reviews the therapeutic use of interferons and other cytokines in various viral, tumorous, and inflammatory diseases, discussing their biological effects and potential future applications without presenting new experimental results.

This article offers a viewpoint on hidradenitis suppurativa pathogenesis, suggesting that impaired Notch signalling from γ-secretase mutations may drive inflammation and link the condition to other Th17-driven diseases.

This article discusses skin lesions in chronic graft-versus-host disease and highlights the importance of coordinated care between haematologists and dermatologists for effective management; it presents no new clinical results.

This study found that dermoscopy combined with calcium fluorescent white staining effectively aided in the early diagnosis and treatment evaluation of tinea capitis by highlighting specific hair changes and fluorescent patterns associated with different dermatophyte infections in a sample of 20 patients.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This study found that CMV infection in a mouse model of allogeneic transplantation was associated with increased allo-reactive T cell expansion and exacerbated graft-versus-host disease, highlighting the need for effective GvHD prophylaxis and treatment.

HIV can cause various nail and hair disorders, important for early diagnosis and treatment.

Elderly patients have more severe hidradenitis suppurativa and may need different treatments.

This case report describes the first known association of hypertrichosis lanuginosa acquisita with autoimmune hepatitis, expanding the list of conditions linked to this rare disorder.

This study found that the mutant hairless rhino bald protein in mice interacts with the vitamin D receptor but cannot repress its transactivation and shows abnormal cellular localization.

In this case report, a 17-year-old Korean female with Vogt–Koyanagi–Harada syndrome showed positive improvement in her symptoms following systemic glucocorticosteroid pulse therapy, highlighting the rarity and importance of early disease detection.

This study found that both desmoglein-specific and non-desmoglein autoantibodies may play active roles in Pemphigus vulgaris pathogenesis, with HLA genetics influencing autoimmune specificity.

This study found that untreated hirsute patients have lower expression of type 2 17β-HSD mRNA in scalp hairs, indicating potential disturbances in androgen metabolism, compared to treated hirsute patients.

In this study, researchers identified a novel and two previously reported pathogenic mutations in the HR gene associated with atrichia with papular lesions in five Pakistani families.

This study found that viral warts were the most prevalent skin condition among pediatric patients, emphasizing the importance of HPV prevention in public health efforts for children.
