This chapter reviews a case of colour dilution alopecia in a Dobermann, offering insights into the clinical progression, differential diagnoses, and treatment options but reports no new findings.

This review found that dermatological manifestations often indicate systemic diseases, with endocrine-metabolic disorders, autoimmune diseases, and renal or hepatic conditions frequently linked to specific skin changes, highlighting the diagnostic importance of skin examination in internal medicine and endocrinology.

This case study described a Staffordshire Bull Terrier diagnosed with alopecia by color dilution, characterized by gradual hair loss and confirmed through clinical examination and histopathology.

This review discusses the mechanisms of hair repigmentation and reports no clinical results; the authors suggest further research into topical treatments for reversing gray hair.

This case study describes a unique patient with dermatomyositis who exhibited features of pityriasis rubra pilaris and porokeratosis, suggesting markers for malignancy warranting thorough investigation and monitoring.

This study identified a compound heterozygous mutation in a hairless rhesus macaque, which was associated with skin abnormalities similar to those in hairless mice and humans with APL.

This case report describes a healthy 27-year-old woman with progressive alopecia and hyperpigmentation on her forehead and frontal scalp, with limited response to triamcinolone acetonide treatment.

This study observed an outbreak of dermatophytosis caused by Trichophyton species in farmed mink in the USA, affecting primarily dark-colored kits with skin lesions.

This study explored spontaneous repigmentation after phenol-croton oil peels in skin of color, finding that temporary hypopigmentation resolved by day 21 in both a black-skin domestic pig model and human clinical observations, highlighting potential for these procedures despite past concerns about pigmentation issues.

Older men's scalp damage increases with age and sun exposure, a baby girl in the Philippines has Schimmelpenning syndrome, and thyroid screening is advised for children with hair loss and certain risk factors.

This study reported that a bioderived melanoidin/tannic acid nanocomplex forms a durable, antioxidant-active coating on hair fibers, providing enhanced UV protection and improving tensile resilience by suppressing oxidative stress and activating endogenous antioxidant pathways.

In this study, researchers found that exosomes derived from Pinctada martensii mucus can effectively inhibit melanin production in melanoma cells and zebrafish without adverse effects, potentially offering a promising therapeutic strategy for treating pigmentary disorders by modulating the NF-κB signaling pathway.

Postinflammatory hyperpigmentation causes dark skin patches and needs personalized treatment.

Older adults commonly experience wrinkles, itchy skin, psoriasis, fungal infections, skin growths, grey hair, hair loss, and nail ridging, but no skin cancer was found in this group.

This study reports two cases where lichen planus developed only in depigmented areas of vitiligo, supporting possible theories of trauma or photodamage triggering this occurrence.

This article evaluates reflectance confocal microscopy features of scalp melanoma but reports no new clinical results, suggesting further investigation is needed.

This study found that dual inhibition of BACE1 and BACE2 in mice affects melanosome maturation and causes dose-dependent hair depigmentation without altering retinal morphology.

This study found that adult patients with Myotonic Dystrophy type 1 exhibited a higher prevalence of various morphofunctional, inflammatory, and proliferative skin disorders compared to healthy controls.

This review summarizes physiologic skin changes during pregnancy and specific pregnancy-related dermatoses but reports no new clinical results.

In this study, dogs with Vitamin A deficiency showed significant clinical and hematological improvement after receiving Vitamin A supplementation.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This case report describes an 18-year-old man with pili annulati, characterized by a "shagreened" appearance of the hair shaft with alternate bright and dark bands and wide holes throughout the cortex.

This case series describes Erythromelanosis follicularis faciei et colli in five Indian patients, suggesting it may be more common than currently reported.

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.

In this case report, a 14-year-old boy was diagnosed with nevus comedonicus, a condition characterized by dilated follicular openings filled with keratin, presenting in a Blaschkoid pattern; treatment with topical tretinoin 0.1% cream was recommended.

This study found that Notch signaling is crucial for maintaining proper melanocyte distribution and preventing premature differentiation in the melanocyte lineage within hair follicles.

This study observed that skin pigmentation significantly attenuates bioluminescent signals in C57Bl/6 mice, complicating quantitative optical imaging and requiring consideration in experimental design.

This abstract provides no research results, focusing instead on navigation and subscription details for JAMA Dermatology content access.

This report describes a rare case of a three-day-old male with ichthyosis hystrix type of epidermal nevus, featuring specific skin and hair symptoms but no nail or skeletal abnormalities.

This article discusses hair and nail research contributions in dermatology but reports no new clinical findings.
