This case report describes an unusual nail tumor termed "onycholemmal horn" in a 77-year-old woman, highlighting its distinct histopathological features and the importance of excisional biopsy for accurate diagnosis.

This case study details the successful use of metyrapone to manage severe Cushing’s disease symptoms and stabilize a patient’s biochemical parameters before she underwent pituitary surgery.

In this case report, an African American male with signs of acne keloidalis nuchae highlights the condition's chronic nature and need for early intervention to minimize permanent scarring and its psychosocial impact.

Focal palmoplantar callosities may help diagnose non-Herlitz junctional epidermolysis bullosa.

In this study, researchers found that the cornification process in the nuptial pads of Xenopus frogs involves the expression of the type II hair keratin homolog, krt59, and is regulated by the transcription factor hoxc13, showing similarities to mammalian hair evolution.

This study reports that a new nude allele, nu(StL), encodes a truncated Whn transcription factor affecting T-cell development and keratin gene expression, with notable differences from the original Whn(nu) mutation.

This study found that nail and hair changes were predominantly observed in patients with stage 5D chronic kidney disease, with the most common changes being half and half nails and sparse scalp hair.

Excision and laser techniques can effectively treat acne keloidalis nuchae.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

In this report, an 11-year-old girl and her 14-year-old brother developed marking nut dermatitis from an amulet, highlighting the importance of recognizing cultural practices in diagnosing skin conditions.

This article describes the "naked" mouse mutation, which results in hair loss and is linked to chromosome 15, noting similarities and differences with human ectodermal dysplasia, but provides no new experimental findings.

This study explores ear pinna development in mice and reports that elastic cartilage formation is disrupted in a short ear mutant, correlating with increased adult adipocytes and impaired chondrogenesis.

In this study, researchers found that skin pigmentation alterations in a mouse model of Carney complex may be caused by specific dermal fibroblasts promoting melanogenic signaling.

This study identified that patients with compound heterozygous mutations in FOXN1 exhibited severe T-cell lymphopenia but retained normal hair and nail development, indicating a distinct clinical phenotype from classic FOXN1 cases.

This review discusses advances in understanding tickling sensations and proposes that knismesis hypersensitivity in autism spectrum disorder may be due to impaired sensory integration.

This study found significant correlations between scalp and nail involvement and laboratory findings in Korean patients with chronic cutaneous lupus erythematosus, highlighting their importance for diagnosis and management.

Mouse tail skin has different keratinization near hair follicles and scales.

In this study, Flii overexpression in mice enhanced fingertip regeneration and nail formation after both distal and proximal amputations, suggesting a role in digit and hair follicle regeneration possibly involving Wnt signaling.

This case report found that a 48-year-old woman with idiopathic twenty-nail dystrophy experienced significant improvement in nail appearance after six months of treatment with oral Upadacitinib.

This case report describes a unique presentation of porokeratotic eccrine ostial and dermal duct nevus with lesions on the dorsum of the hand and a focal lichenoid infiltrate, differing from typical palm and sole involvement.

This study found that while most mice lacking MK6a and MK6b genes died from tongue epithelium disintegration, about 25% survived and showed no hair or nail defects due to a newly discovered MK6hf gene.

This study suggests that the NCSTN knockout mouse could serve as an HS animal model, with tamoxifen potentially used for gene deletion in mice.

This study found that sensory and sympathetic innervation in the mystacial pads of mice is governed by a balance of neurotrophin signaling, highlighting the roles of NGF/trkA and NT-3/trkC pathways.

This study assessed the use of a levered nail trimmer, finding that it may improve ease of nail trimming, enhance personal comfort, and potentially benefit general health and wellness, including reduced injury risk for bald individuals of all ages and backgrounds.

This study identified a new pathogenic variant, c.1081G>T; p.(Glu361*), in the KRT31 gene as a cause of autosomal-dominant monilethrix, highlighting the role of hair keratin proteins in hair and nail tissue disorders.

This study suggests that the structural integrity and physical proximity of Whn's DNA binding and activation domains are crucial for hair keratin gene activation and may explain the nude phenotype.

This article discusses recent advances in understanding the mechanisms of tactile end organs in the epidermis and hair follicles from studies of mouse hairy skin, but it reports no new clinical results.

This study reports that four Indian patients with acne keloidalis nuchae also exhibited acanthosis nigricans, suggesting a potential link to metabolic syndrome, though further research is needed to confirm this association.

This study explored the dermatological phenomena associated with sports and clinical scenarios, detailing unique conditions like "Athlete's nodule," "Runner's toe," and "Swimmer's ear," along with their diagnostic features and management strategies, uncovering how sports activities inform dermatological terminology and practice.
