This article presents a case of an 8-year-old boy with Recklinghausen's disease showing features such as café-au-lait spots, alopecia, and developmental anomalies, but reports no new findings beyond observation.

This study found that the switch-off of melanogenesis during the hair cycle in C57 BL-6 mice is a gradual and stochastic process starting in mid anagen VI, with specific biochemical markers indicating the transition to catagen.

People of African or Asian descent have unique skin issues that need special care.

This study found that ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

In this study, researchers classified melanomas by filaggrin expression levels and found that in filaggrin^High melanomas, there are significant changes in FGFR signaling and impaired GNA14 and Th1 signatures, linked to genetic and immune alterations associated with pruritus.

SPRY1 deficiency in skin cells causes stem cells to move to the skin surface, leading to increased pigmentation.

This article reviews the clinical presentations, pathophysiology, and treatment options for various skin conditions in children with skin of color and reports no new findings.

This review discusses the potential autoimmune etiology of vitiligo and its association with other autoimmune diseases but provides no new research findings; the authors highlight various treatment options.

This case report suggests that identifying hyperpigmentation on the upper eyelid with specific dermoscopy patterns could help diagnose facial lichen planus pigmentosus without needing a facial biopsy.

In this study, Desmodesmus pannonicus water extract demonstrated significant antioxidative properties, inhibited melanin production, promoted wound healing in human keratinocyte cells, and showed potential for hair growth enhancement in human follicle dermal papilla cells, suggesting its promise for future dermatological applications.

This case study documented a black male newborn developing large bullae that healed with hypopigmentation, suspecting proteolytic enzymes in keratinocytes caused the collagenolysis responsible for the condition.

This review discusses the role of various cells outside the hair follicle in regulating melanocyte stem cells and hair graying, but reports no new clinical results.

This case report details the lack of confluent repigmentation in an 8-year-old girl with vitiligo after three years of trioxsalen and ultraviolet light treatment.

In this study, researchers found that patients with psoriasis had a higher probability of achieving and maintaining a clinical response using brodalumab compared to ustekinumab over 52 weeks, as measured by a multistate modelling approach based on absolute PASI scores.

This review discusses the role of zebrafish as a model for studying human hereditary pigmentary disorders and reports no new experimental results, emphasizing their genetic similarities and the genetic tools available.

This case report documents an unusual instance of follicular vitiligo in a young woman, characterized by selective hair depigmentation on the forearms, distinctive dermoscopic and Wood's lamp findings, and histological evidence suggesting functional impairment rather than complete loss of follicular melanocytes.

This case report describes a black male newborn who developed bullae that healed with hypopigmentation, linked to collagenolysis and RER vacuoles potentially containing proteolytic enzymes.

This study found that mitochondrial fusion regulator Opa1 is crucial for maintaining melanocyte stem cells during the hair follicle cycle in mice, with Opa1 deficiency leading to impaired SCF-KIT signaling, reduced melanocyte populations, and early hair graying.

This review highlights the role of the skin's photosensory system in mediating responses to UVA radiation, contributing both to immediate protective effects and to broader circadian and seasonal adaptations, but reports no new experimental results.

This review examines the pathogenesis of premature hair graying and potential treatment avenues, but reports no new experimental outcomes, highlighting ongoing research challenges and hopes for drug development.

RAPK is a rare skin disorder with pigmented spots, mainly on hands and feet, starting in youth.

Two patients had a rare combination of red skin spots and white scaly skin lesions not on the genitals.

This article discusses mouse genetic studies to explore factors influencing melanogenesis, highlighting pH and cysteine's roles, and proposes a hypothesis for human hair color diversity; it reports no new results.

Hair graying may help prevent cancer by protecting stem cells.

In this study, researchers found that cyclophosphamide treatment unexpectedly reduced splenic melanin deposition in a murine model, whereas this effect was down-regulated more by the normal and dystrophic catagen phase of the hair cycle.

In this study, lower serum adiponectin levels and altered lipid profiles were observed in patients with periorbital melanosis, suggesting an association with metabolic syndrome.

This case study describes a 21-year-old male diagnosed with Becker's nevus, characterized by hyperpigmented and hypertrichotic lesions that developed over several years.

This review discusses the clinical manifestations and genetic basis of pigmentary mosaicism, highlighting its varied phenotypic expressions, but reports no new clinical results.
