This review discusses the complex relationship between anabolic substances and colorectal cancer risk, reporting ambiguous findings on their carcinogenic properties, potential synergy with risk factors, and protective roles.

This study found that patients with vitiligo and alopecia areata had significantly higher serum granulysin levels compared to healthy controls, indicating a potential pathogenic role and suggesting that elevated levels may serve as a biomarker for monitoring disease activity, particularly in active vitiligo cases.

This study reports that vitiligo prevalence in a Saudi cohort is similar to global figures, with stress as a common trigger, frequent lesional pruritus, and widespread thyroid issues and low vitamin D levels.

This study reported that depleting the pro-apoptotic protein Bax in hair follicle stem cells enables these cells to kill nearby viable cells by sequestering TNFα, which increases the stem cell pool and accelerates tissue regeneration, suggesting potential implications for therapies targeting tissue repair and cancer.

This article discusses the potential involvement of hair follicle melanocytes in follicular vitiligo, noting a pattern of depigmentation centered on follicles and supported by inflammatory infiltrates, without reporting new clinical results.

This article reviews the rare skin disorder ichthyosis with confetti, highlighting the potential for future therapies using revertant stem cells, and reports no new clinical results.

This study found clinical markers like leukotrichia and trichrome lesions in non-segmental vitiligo patients were linked to greater disease extent and poor response to treatment.

This review discusses the roles of hormonal pathways in regulating male sexual function, particularly highlighting the impact of testosterone, and reports no new research findings.

This study found that hyperpigmentation following contact immunotherapy for severe alopecia areata may indicate poor treatment responsiveness and aligns with characteristics of pigmented contact dermatitis.

This meeting report discusses the first symposium on natural gene therapy for skin, preceding the 41st annual meeting of the European Society for Dermatological Research, and reports no new experimental findings.

Topical eyedrops may cause eyelash whitening and skin lightening around the eyes.

Turning scar-forming cells into fat cells can reduce scarring.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This review explores the causes and mechanisms of alopecia areata and discusses current treatments, reporting no new clinical findings.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This article describes the development milestones and recent approvals of ritlecitinib for treating severe alopecia areata, with approvals in the USA and Japan and ongoing regulatory reviews in other regions.

This review discusses evidence for alopecia areata treatments, highlighting their ability to stimulate hair growth but noting limited data on long-term efficacy and impact on quality of life.

Graft-versus-host disease is a complication where donor immune cells attack the recipient's body, often affecting the skin, liver, and gastrointestinal tract.

This review discusses updated treatment guidelines for alopecia areata in Japan, highlighting new options like corticosteroid pulse therapy, but reports no new clinical results.

This review examines topical immunotherapy for severe alopecia areata, noting that diphencyprone and squaric acid dibutylester are non-mutagenic options with similar efficacy but different practical considerations, and reports no new clinical results.

This review discusses topical and intralesional treatments for alopecia areata, providing a management strategy based on patient age and disease severity, but reports no new clinical results.

This article discusses less commonly used and experimental treatments for vitiligo, focusing on therapies other than psoralen, but does not report new clinical results.

This review discusses various treatment options for alopecia areata tailored by age and severity, providing a practical algorithm, but reports no new clinical results.

This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.

This study reports cases of androgenetic alopecia patients with depigmented macules on sun-exposed scalp areas, suggesting potential ultraviolet-induced scalp leukoderma not covered in existing dermatology texts.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

This study suggests that hydroxypinacolone retinoate (HPR) may be an effective alternative to tretinoin for anti-aging skin treatments, offering similar collagen production benefits without increased skin irritation.

This review discusses the pathomechanism and pathology of alopecia areata, its classifications, and associated diseases, but reports no new clinical results, highlighting the importance for current and future treatment considerations.
