This study found that the yellow dot pattern observed in dermoscopy of alopecia areata corresponds to inefficient follicular structures containing hair remnants, as corroborated by reflectance confocal microscopy and pathological findings.

This study reported that imaging characteristics of sebaceous nevus vary significantly by age group, revealing dynamic developmental changes that can be effectively identified through dermoscopy and reflectance confocal microscopy, offering noninvasive diagnostic potential.

This study found that combining dermoscopy with reflectance confocal microscopy is more sensitive and specific than using either method alone for assessing vitiligo disease activity and treatment response. Additionally, specific characteristics observed via these techniques correlated with either good or poor treatment outcomes.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

Polarizing light microscopy can easily and reliably diagnose congenital keratinizing disorders like Netherton syndrome.

This study found that multiphoton microscopy imaging allows for detailed observation and quantitative analysis of collagen alterations in the progression of endometrial cancer, potentially offering a faster, more accurate method for early diagnosis compared to current protocols.

This study found that intracorneal vacuoles were common in various parakeratotic skin diseases in dogs, but large vacuoles were exclusively observed in congenital follicular parakeratosis.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This case report describes a patient with trichothiodystrophy presenting with autism, mental retardation, and seizures, characterized by distinct hair abnormalities under microscopy.

This study found that loose anagen syndrome was more common in females and observed across all hair colors and skin types.

This review outlines the diagnostic criteria for congenital and hereditary hair shaft abnormalities and emphasizes the need to understand the weathering process in assessing these disorders.

This case report describes a 45-year-old woman with diffuse nonscarring alopecia characterized by hair thinning, increased catagen/telogen follicles, and mild inflammatory infiltrate, highlighting the diagnostic findings via scalp dermoscopy and biopsy.

This study found that careful light microscopy using fluid-mounted hair improves detection of the pili annulati phenotype, which varies widely in expression and affects hair fragility.

This article discusses the complexities in diagnosing hair shaft disorders and the potential insights hair microscopy can provide, without reporting new clinical findings.

Dermoscopy greatly improves melanoma diagnosis and reduces unneeded surgeries.

A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.

This abstract provides no results; it is a website notification about cookies and general access to JAMA content.

This review discusses hair shaft disorders, noting the lack of specific treatments and recommending general care practices to prevent hair damage, with some improvement possible during puberty or with treatments like minoxidil.

This article describes various hair and scalp examination techniques, including noninvasive, semi-invasive, and invasive methods, noting that trichoscopy is a simple, well-accepted, noninvasive technique for evaluating hair loss patients and monitoring treatment.

This case report describes an instance of autosomal recessive uncombable hair syndrome caused by maternal uniparental disomy of chromosome 1.

This report describes a new case of isolated trichothiodystrophy with characteristic brittle hair and suggests a simplified classification scheme for understanding sulfur-deficient hair disorders.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

This case report describes a 6-year-old girl diagnosed with the rare concurrence of monilethrix and trichorrhexis nodosa, characterized by sparse, brittle hair, who showed minimal clinical improvement with low-dose oral and topical minoxidil treatment.

This article discusses various forms of alopecia, emphasizing the need for light microscopy to investigate hair shaft disorders, and does not report new clinical findings.

This study suggests that while low-cost USB microscopes can correctly identify certain hair shaft features, their ability to detect other crucial trichoscopic features is limited, indicating they are not reliable for routine scalp assessments without further trials.

This article reviews advances in the histologic evaluation of alopecia and hair-related disorders, without presenting new clinical results.

This study highlights how examining hair histology under a microscope helps forensic analysts identify animal species by distinguishing specific microscopic features, which supports accurate reference database creation and aids crime scene investigations.

Sorafenib may cause hair loss in a way similar to alopecia areata.

A young man was unexpectedly diagnosed with basal cell carcinoma after a scalp examination and confocal microscopy.
