This article discusses pigmentation disorders in veterinary dermatology, focusing on the role of melanogenic pigmentation, and reports no new research results.

This case report details a 21-year-old woman with dermatopathia pigmentosa reticularis, presenting with generalized reticulate hyperpigmentation, diffuse noncicatricial alopecia, onychodystrophy, palmoplantar keratoderma, and poorly developed dermatoglyphics.

In this study, stable types of leucoderma such as segmental vitiligo and piebaldism showed 100% repigmentation after melanocyte transplantation, suggesting surgery as the preferred method for these conditions.

This review discusses the diagnosis and treatment of pityriasis rubra pilaris and reports no new clinical results.

This paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

A new gene mutation may allow some piebaldism patients to regain skin color in white patches.

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 case report suggests that melanin, as an energy generator, may offer a new perspective on studying and treating autoimmune disorders such as alopecia areata.

This case report describes a rare instance of melanocytic matricoma, a benign pigmented papule found in sun-damaged skin of an elderly individual, highlighting its distinct clinical and pathological features.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

Repigmentation in vitiligo may come from melanocyte stem cells in the skin.

This report discusses a case of an intradermal nevus in a 42-year-old woman and provides no clinical findings beyond a biopsy showing hyperkeratosis and cellular pigmentary changes.

This study reported that gain-of-function mutations in TRPV3 lead to hair loss in mice by disrupting inner root sheath keratinocyte differentiation, ultimately causing follicular keratinocyte stem cell exhaustion and permanent follicle disruption.

This review examined and discussed the role of dermis-derived factors in the regulation of melanogenesis, noting their significance in both normal and abnormal mammalian skin conditions, suggesting an underexplored area of study compared to dermal and epidermal influences.

A 73-year-old man's grey-white hair turned dark brown after eczema treatment.

This article reviews the effects of melatonin on skin pigmentation from frogs to humans and presents no new experimental findings, highlighting the need for further research into its dermatological applications.

This case study describes an elderly woman with distinctive black hair patches and scalp pigmentation, but it does not provide a diagnosis or new findings.

This abstract contains navigation and subscription information for JAMA Dermatology and reports no new clinical findings.

This case report describes a rare instance of reversible melasma-like hyperpigmentation linked to vitamin B12 deficiency due to pernicious anemia, and explores possible mechanisms for this association.

This article discusses dermatological issues associated with black skin, such as postinflammatory pigmentation and keloids, and highlights the need for practitioners to understand these racial characteristics; it reports no new clinical results.

In this case report, a 20-year-old man with a birthmark was identified as having a supernumerary nipple, a developmental anomaly, using dermoscopy to distinguish it from other pigmented skin lesions such as melanocytic nevus or basal cell carcinoma.

This article reviews literature indicating that specific dermatoses manifest differently in black skin compared to lightly pigmented skin, with some conditions more prevalent or unique to black skin, emphasizing the need for tailored clinical recognition and management.

This study confirms that human CD34+ melanocyte stem cells can be differentiated into melanin-producing cells, suggesting potential for cellular therapy in treating skin degenerative diseases.

This case report describes perifollicular melanocyte regeneration in the affected skin of a patient with bullous pemphigoid, highlighting an underreported aspect of the condition in skin of color patients, and emphasizing the need for increased awareness and earlier diagnosis in this demographic.

This source explores melatonin's roles beyond circadian rhythm regulation, reporting its benefits in skin conditions like dermatitis, melasma, alopecia, psoriasis, and skin aging due to its antioxidant, anti-inflammatory, and immunomodulatory properties, while highlighting the need for more trials on optimal dosing and long-term safety.

This review discusses the early phases of melanomagenesis and the factors influencing melanoma cell variability and reports no new clinical results.

This study introduced and evaluated a new dermoscopic feature, pigmented rings with central clearing, for improving the diagnosis of melasma and differentiating it from similar conditions.

This study investigated the pigments and cells causing discoloration in stasis dermatitis but did not clarify the role of melanin or melanocytes in this condition.

Vitiligo causes white skin patches and is linked to autoimmune issues.

This article reviews the clinical features of dermatopathia pigmentosa reticularis, highlighting its characteristic triad of symptoms, but provides no new research results.
