This review discusses the heterogeneity and plasticity of epithelial stem cells in skin homeostasis, wound healing, and tumorigenesis, reporting no new results but emphasizing the need for further exploration of key regulatory mechanisms.

This review discusses the effects of the epidermal growth factor receptor system on skin biology and pathology, relying on animal models to analyze roles in cellular processes, wound healing, and tumorigenesis, but reports no new results.

This article reviews various medical treatments for hidradenitis suppurativa based on the author's experience with over 350 patients, but it reports no new clinical findings.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

This study demonstrates that confocal laser scanning microscopy can effectively visualize the rapid diffusion and penetration pathway of a dye into the hair follicle in fresh human scalp skin.

This review discusses varying views on the pathogenesis of hidradenitis suppurativa and the challenges in achieving a consensus, emphasizing the need for further research rather than providing new findings.

This study found that specific gene upregulations and mutations in hidradenitis suppurativa skin support the role of inflammation, altered epithelial differentiation, and metabolism dysregulation in the disease's pathogenesis.

This review discusses the interactions between immune cells and the skin epithelium and their impact on maintaining barrier function, emphasizing the potential to enhance epithelial barrier function in inflammatory diseases.

This study found that the expressions of CDK inhibitors p21waf1/cip1 and p27kip1 were higher during the anagen phase compared to telogen, suggesting a role in follicular epithelial cell differentiation.

This review discusses various perspectives on the pathogenesis, classification, and contributing factors of hidradenitis suppurativa and reports no new experimental results; the authors call for further studies to advance understanding and treatment.

This review discusses genetically-engineered mouse models for studying melanocytes and reports no new experimental findings; it emphasizes their potential to address unanswered questions in melanoma biology.

This review hypothesizes that nicotine plays a crucial role in the pathogenesis of hidradenitis suppurativa by promoting inflammation and microbial growth, suggesting that anticholinergic agents might be a potential treatment strategy, but reports no new clinical findings.

This review elaborates on the concept of cutaneous mosaicism and its link to acneiform conditions, but it reports no new clinical results.

This review examines the clinicopathologic features of perifollicular elastolysis and indicates that, while its presentation is consistent, there is a lack of high-certainty evidence for effective treatments.

This study found that ethosomes containing 30% ethanol slightly improved the targeting of dutasteride to hair follicles in vitro, with a higher targeting factor compared to dried ethosomes and controls after 24 hours on porcine skin.

This review discusses the genetic causes and pathogenesis of Olmsted syndrome, emphasizing the potential for a genotype-phenotype correlation due to TRPV3 mutations, and explores avenues for individualized treatment developments for this condition.

This study reports that Hair RiseTM microemulsion, made from plant extracts, significantly enhanced hair follicle cell growth and improved hair growth signaling pathways, suggesting it as a plant-based alternative for androgenetic alopecia treatment.

This study is the first to detail major geriatric diseases in aged Julia Creek dunnarts, particularly highlighting hormonal issues like cystic glandular hyperplasia in females and testicular degeneration in males, suggesting these conditions are linked to aging and potentially hormonal dysregulation.

This report describes a case study of a 23-year-old female exhibiting multiple trichodiscomas, a type of benign tumor of the hair follicular discs common in familial cases and potentially linked to Birt-Hogg-Dube syndrome, though genetic testing was not performed due to financial constraints.

This source highlights the challenges in treating cicatricial alopecia, noting that follicular unit extraction hair transplantation offers a minimally invasive and successful option to improve cosmetic outcomes for patients with permanent hair loss from scarring.

In this scoping review, researchers observed that while AI-assisted trichoscopy holds promise for standardized assessments of hair and scalp disorders, its clinical translation is limited by small proprietary datasets, inconsistent validation protocols, and a scarcity of real-world clinical studies.

This article describes adult female acne as a complex condition affected by genetic, hormonal, and environmental factors, with hormonal therapies highlighted as particularly valuable for treatment.

In this research, authors found that skin-resident ILCs regulate sebaceous gland function and microbial balance, emphasizing an immune-epithelia system that supports host-microbe symbiosis.

This study identified genetic variants in the DSG4 gene associated with the autosomal recessive form of monilethrix in Chinese patients, expanding the understanding of its phenotypic spectrum and clinical features.

Stem cell therapies might help with hair loss, but more research is needed to confirm their safety and effectiveness.

This study highlights IGF-1's role in promoting hair follicle proliferation, vascularization, and growth, suggesting its potential as a treatment target for hair loss disorders like androgenetic alopecia, though more research on delivery methods and long-term effects is needed.

The study observed that patterned fibrosing alopecia, a type of scarring hair loss, appears in some patients after hair transplants, facelifts, and other surgical interventions, sharing features with lichen planopilaris and androgenetic alopecia.

This review discusses the significant progress in the diagnosis and treatment of hair loss disorders over the last 30 years and reports no new clinical results.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This study revealed that Patched receptors establish a Hedgehog signaling gradient in developing hair follicles, which may influence their formation and potentially offer a diagnostic tool for distinguishing Hedgehog-driven tumors.
