In this case report, the authors found that pigmented demodicosis, caused by Demodex mites, led to facial hyperpigmentation in a 16-year-old male and showed significant improvement with oral isotretinoin and topical ivermectin treatment.

The document concludes that skin and nail changes can indicate various underlying health conditions.

This study found that non-vitiliginous melanocyte stem cells from vitiligo patients were unaffected by the disease and could effectively differentiate into melanin-producing melanocytes, suggesting their potential for use in cellular therapy for vitiligo repigmentation.

This letter to the editor raises the possibility of a new medical entity characterized by symptoms such as poikiloderma, hyperpigmentation, alopecia, malformed bones, lymphedema, and decreased cortisol, but provides no clinical results.

This review discusses various therapeutic roles of melatonin, particularly its antioxidant and sleep-regulating properties, for skin and scalp conditions, and reports no new clinical results.

Fibroblasts can be turned into melanocytes for potential skin treatments.

This review discusses various skin diseases with endocrinological origins and reports no clinical results, highlighting the need for interdisciplinary understanding in diagnosis.

This study concluded that hair pigmentation, as measured by eumelanin-to-pheomelanin ratio, is not a risk factor for developing alopecia areata when compared to androgenetic alopecia patients.

This animal study observed that while topical MBEH and intraperitoneal phenol induced hair graying in eumelanic mice, they had little effect on pheomelanic mice, and amcinonide reduced certain epidermal melanocytes in both.

This article discusses two cases of the rare combination of frontal fibrosing alopecia and lichenoid pigmentation in women, but reports no new clinical results.

This study found that oxidative stress in hair follicle melanocytes contributes to premature aging and apoptosis, providing insights into graying as a model for studying aging and testing antiaging therapies.

This review discusses the clinical characteristics, causative factors, and treatment options for vitiligo and reports no new research findings.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

This article reviews skin disorders in Parkinson's disease, highlighting the potential of skin studies and stem cell research to advance understanding and treatment of the neurodegenerative disorder, without presenting new results.

Intradermal PRP significantly improved melasma in dark skin, with lasting results and no relapse after 3 months.

This article reviews the role of melanins in determining human hair color and discusses the specialized regulation of hair melanocytes during growth, with no new findings reported.

This study observed that the aqueous extract of roasted Alocasia macrorrhizos tubers led to hair follicle repigmentation and reduced epidermal thickness in a murine model of Vitiligo.

This study reviewed existing literature and reported two cases of perinevoid alopecia, suggesting that melanocyte antigens may be involved in its development.

This article discusses melatonin's role in mammalian coat color and its potential in melanoma treatment when used with chemotherapy, but reports no new clinical results.

This review evaluated the evidence on skin disorders linked to levodopa treatment for Parkinson's disease, suggesting a possible association with melanoma, though evidence remains inconclusive and further studies are needed.

This study found that non-pigmented hair follicles have significantly lower expression of nucleotide excision repair genes, which may be associated with reduced melanin production capacity in these follicles.

This case study reports a patient with Rothmund-Thomson type congenital poikiloderma, showing primarily skin changes and hair loss, along with slightly elevated lysine and cystine levels in urine.

This case report describes koebnerization-induced vitiligo in a woman following repeated eyebrow microblading, suggesting a link between the procedure and the phenomenon in susceptible individuals.

In this study, researchers observed that Melan A, a melanocytic marker, was significantly expressed in hair follicles of alopecia areata patients and correlated with immune infiltrates, suggesting melanocytes might contribute to the autoimmune response in this condition.

This study highlights restorative dermopigmentation as a growing field in aesthetic medicine, aiming to address skin concerns like alopecia and age-related pigment loss by improving aesthetic and structural dermal deficits.

This study found that Sox2 within dermal papilla cells in the hair follicle regulates hair pigmentation, influencing the type and production of melanin.

In this study, researchers identified key genes such as EDNRB2, GPNMB, TRPM1, TYR, and DCT that regulate melanin deposition in the breast muscles of black-boned chickens, contributing to their unique pigmentation during embryonic development.

This review highlights the diverse roles of melanocytes in pigmentation, immunity, and hearing among other functions, their involvement in disorders, and their emerging potential in regenerative medicine, including applications in disease modeling and therapy development using advanced technologies.
