This study found that line-field confocal optical coherence tomography effectively visualized microscopic alterations in alopecia areata, suggesting its potential use in diagnosis and monitoring.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study describes a modified reduction-osmication method for staining human scalp hair that improves reagent penetration and visualization of hair cortex features using transmission electron microscopy.

In this study, a system was developed utilizing advanced image processing to analyze hair and scalp conditions, aiding professionals in diagnosing diseases like alopecia and monitoring treatment by extracting and comparing key parameters from microscopic images.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This report provides the first microscopic description of pachyonychia congenita-associated alopecia, identifying a combination of histological features that might be unique to this condition.

This study investigated the hair structure of wild pigs in the Balıkesir region using stereomicroscopy and scanning electron microscopy, finding distinct bifurcation patterns, but concluded that pig bristles used in brushes likely wouldn't retain these features, complicating species identification.

This study examined the morphological variations of terminal hair from different body regions of a Caucasian male, finding notable differences in diameter and features like "steak-boning" in specific hair types.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This study concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

This article reviews the clinical and diagnostic features of hair shaft disorders, emphasizing the role of structured patient assessments and the avoidance of hair trauma, but reports no new results.

This case report describes the characteristic clinicopathological features of trichodysplasia spinulosa in two boys with acute lymphocytic leukemia, highlighting its resolution as immune function normalizes.

This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

This pilot study employed in-vivo multiphoton microscopy to visualize pigment-producing melanocytes in vitiligo patients, aiming to enhance understanding of treatment impacts and potentially improve transplantation therapies.

This study reported that connective tissue nevi show distinctive dermoscopic and RCM features, with RCM being particularly helpful for diagnosing lesions of less than one year in duration.

This study observed that human hair keratin showed distinct morphological features depending on the dissolution speed, which could have potential applications in clinical settings for developing self-tendons.

This article reviews trichoscopic techniques for diagnosing common hair loss conditions and presents a revised algorithm for identifying specific features of cicatricial and noncicatricial alopecia, but reports no new clinical results.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This review discusses the epidemiology, risk factors, clinical features, and management of scalp melanomas, highlighting their high mortality rates and specific challenges in diagnosis and treatment; it reports no new research findings.

In this study, researchers used a hypospadiac rat model to demonstrate abnormal genital development, similar to human penoscrotal hypospadias, highlighting the model's value for studying penile growth and differentiation.

This study identified distinct microscopic characteristics of acne scars, including inflammatory infiltrates and insufficient collagen deposition, suggesting that treatment should consider these histopathological findings and employ combination therapy.

This study reports that flaky skin mice exhibit skin and nail features that closely resemble human psoriasis vulgaris, suggesting they may serve as a natural model for this condition.

This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

The document concludes that diagnosing hair loss requires evaluating multiple histological features, as no single feature is definitive on its own.

This study suggests that RCM may be a promising non-invasive diagnostic tool for alopecia areata incognita, showing substantial agreement with histopathology while noting some discrepancies.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.
