Lupus erythematosus panniculitis on the scalp can cause unique geometric hair loss patterns.

This article discusses the use of a high-magnification digital video microscope for diagnosing and treating androgenetic alopecia and reports no new clinical results.

This review discusses primary cicatricial alopecias, detailing their classification, pathogenesis, clinical features, histopathologic findings, and treatment, without reporting new experimental results.

The document's conclusion cannot be provided because the content is not accessible.

This study identified a new variety of central centrifugal cicatricial alopecia that includes patchy hair loss on the lateral and posterior scalp in African-American women, which could be misdiagnosed as traction alopecia without dermatoscopy and pathology.

This study generated a transcriptomic map of human hair follicle compartments, providing a database for identifying compartment-specific gene expression which may aid in developing targeted treatments for hair follicle disorders.

This study reports that yellow dots in a higher number per field of vision were the most consistent dermoscopic finding in severe cases of alopecia areata.

Different types of scarring alopecia may be stages of one disease, and accurate diagnosis is crucial to prevent permanent hair loss.

This case report describes the trichoscopic and histological features observed in a 7-year-old boy with morphea en coup de sabre and details the positive response to systemic immunosuppressive therapy.

This review discusses the use of trichoscopy in diagnosing and managing pediatric hair and scalp disorders and reports no new experimental findings.

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.

This report describes how ultraviolet-induced fluorescence dermoscopy helped accurately diagnose scalp disorders, specifically alopecia areata and tinea capitis, in pediatric patients.

This report documents the second known case of Castleman's disease in the lacrimal gland, diagnosed in an 84-year-old woman through histological examination after excising a left upper lid mass.

This study found that adnexal acantholysis does not reliably distinguish pemphigus vulgaris from pemphigus foliaceus, but the level of acantholysis and degree of dyskeratosis serve as distinguishing features among acantholytic disorders.

This study found that the BASP classification system for pattern hair loss showed better reproducibility and repeatability compared to the Norwood-Hamilton classification.

This study found that human hair follicle dermal papilla cells and keratinocytes self-assembled differently in 3D spheroid co-cultures, providing insights into cell distribution and organogenesis during skin regeneration.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

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.

A 4-year-old girl had a rare hair disorder affecting only part of her scalp.

In this study, trichoscopic examination found distinct hair characteristics for diagnosing eyebrow loss: alopecia areata is marked by features like exclamation mark hairs, while frontal fibrosing alopecia shows dystrophic hairs and distinctive regrowth patterns.

This study found that trichoscopy can diagnose genetic hair shaft abnormalities without plucking or cutting hair, by visualizing characteristic features in a single session.

This study observed that keratosis pilaris is the most prevalent follicular keratotic disease, especially in adolescent and young adult females, and emphasized the key role of dermoscopy and histopathology in distinguishing it from other similar disorders and aiding in diagnosis.

This review discusses the characteristic trichoscopy patterns useful in differentiating lichen planopilaris and frontal fibrosing alopecia from similar conditions but reports no new clinical results.

This study found that the most common form of cicatricial alopecia was lichen planopilaris (27.5%), followed by discoid lupus erythematosus (25%), while perifollicular fibrosis was the prevalent histopathological feature (65%).

This review discusses the histologic features of nonscarring alopecia and highlights the importance of clinical-pathological correlation for accurate diagnosis, but reports no new clinical results.
