This case report highlights a 40-year-old Indian male diagnosed with follicular vitiligo, presenting as graying hair and depigmented patches, and emphasizes the importance of distinguishing this rare variant from similar conditions like alopecia areata due to its unique presentation.

This study reported a gap between podiatrists' frequent encounters with suspicious pigmented foot lesions and their lack of formal melanoma detection training, highlighting a need for improved education and referral pathways.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

Keratins change and are modified differently in skin layers and body parts.

This narrative review discusses lichen planus pigmentosus, including its variations, associated triggers, and management strategies, but reports no new clinical results.

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 study found no evidence that HDGF expression transforms melanocytes into tumors in a mouse model, although it may play a role in cell differentiation and tumor progression.

This case report describes a giant pigmented tumor of the scalp in a 47-year-old woman and suggests a possible dual origin involving neural crest differentiation.

This review discusses how certain skin disorders, pigmentation issues, and hair problems are more common in black individuals than white individuals and does not report new clinical results.

This study suggests that melatonin may promote hair growth properties by activating the AKT/GSK3β/β-catenin signaling pathway in dermal papilla cells.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study found that collagen and its compound may have antioxidant effects and reduce melanin in guinea pigs, while increasing skin moisture and hydroxyproline content in mice.

This review discusses the changes in hair follicles with aging, particularly graying due to decreased melanocyte activity, and suggests potential for hair repigmentation under certain conditions, but reports no new results.

This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.

In this study, only European-ancestry females showed a linear increase in cutaneous malignant melanoma risk with age, potentially due to the loss of HPV-infected androgenic follicles after menopause.

This study reports that aging in mice leads to curved hair follicles and an increase in white hairs, potentially due to changes in keratinocyte and melanocyte stem cells.

This review discusses recent developments in targeted melanoma therapies, including BRAF/MEK/ERK pathway inhibitors and challenges like resistance and skin toxicities, but reports no new clinical results.

This study describes vitiligo as an autoimmune disease marked by depigmented skin and mucosal patches, and reviews its complex pathogenesis and diagnostic features. Treatment aims for disease control and repigmentation through various topical and systemic therapies, phototherapy, and surgical options, emphasizing personalized, multimodal approaches.

This study found that temporary or permanent leukotrichia may occur after intense pulsed light therapy for hair removal, likely due to differing thermal effects on melanocytes and hair follicle cells.

This study found that mimosine dipeptide enantiomers inhibit melanogenesis and cyclooxygenase enzymes in B16F10 melanoma cells, suggesting potential for treating skin hyperpigmentation and inflammation.

This review examines the diagnostic significance of yellow and orange colors in skin lesions and concludes that their role is often underrepresented in the literature.

This study found that gene expression changes in hair bulb cells are linked to graying hair, affecting processes like melanogenesis and cell-cell interaction.

A pregnant woman's skin condition improved after giving birth, possibly due to high estrogen levels during pregnancy.

This study observed that white hair follicles in vitiligo patients may repigment following epithelial grafting and phototherapy, suggesting potential cosmetic improvements in vitiligo treatment.

In this study, researchers found that among women with frontal fibrosing alopecia and hyperpigmented facial lesions, most cases were diagnosed with lichen planus pigmentosus, while some were identified as melasma or drug-induced.

This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.

This study found that pimozide, d-butaclamol, and pituitary pars intermedia grafts darken hair color in agouti C3H Avy mice, suggesting dopaminergic inhibition influences peptide-controlled hair color cycling.

This study found that the novel dermal cooling system was an effective and safe treatment for reducing pigmentation in benign pigmented lesions in Asian patients, with minimal side effects.
