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 study found that specific dermoscopic signs, such as diameter diversity of leukotrichia and Pohl-Pinkus constrictions, were associated with progressive vitiligo, and early-stage melanin synthesis was impaired in vitiligo-associated leukotrichia.

In this case report, an elderly woman was diagnosed with tinea capitis and eyebrow involvement, which was initially misdiagnosed as alopecia areata, illustrating the importance of trichoscopy in correctly identifying this infection even in uncommon sites like the eyebrow.

This study observed that different hair types on Tianzhu white yaks have similar ultrastructures, but coarse hair fibers show distinct structural differences across body parts.

This review assessed trichoscopic findings in folliculotropic mycosis fungoides of the scalp, reporting features like milky-red globules and distinct vascular patterns, but noted the predominance of small studies and the need for larger research to validate trichoscopy's diagnostic utility for this condition.

This study reported that using photomnemonics facilitated accurate histopathologic interpretation of horizontal scalp sections in distinguishing between nonscarring and scarring alopecias by dermatopathologists and residents in a validation test.

This study observed that trichoscopic examination revealed specific signs of secondary post-traumatic cicatricial alopecia in patients with mine-explosive injuries and burns, and reported an 84.1% hair survival rate following transplantation and PRP therapy, with marked improvements in scalp condition after 12 months.

Examining scalp biopsies in different ways helps better diagnose hair loss types.

This article discusses the diagnostic methods for differentiating alopecia areata from similar hair loss conditions and emphasizes the importance of accurate diagnosis, but it reports no new research findings.

This study systematically reviewed clinical findings in trichothiodystrophy patients and suggested a new clinico-genetic classification to help better understand the ichthyotic phenotype and its management.

Dermoscopy can help diagnose tinea capitis in children by looking for comma hairs, black dots, and broken hairs with white bands.

In this study, focal atrichia was associated with late-onset female pattern hair loss, providing a clinical clue to its diagnosis, particularly separating it from other hair disorders.

This study presents a microscopic analysis of the pruritic variant of trichostasis spinulosa in two patients and reviews existing literature, reporting no new clinical results.

This study found that comma hairs are a distinctive feature of tinea capitis caused by Microsporum canis, distinguishing it from alopecia areata, which is characterized by exclamation mark hairs.

This study found that 'black dots' seen under trichoscopy are not specific to alopecia areata and may occur in various other hair and scalp conditions.

In this study, LC-OCT was used to distinguish between subtypes of scarring alopecia, laying the groundwork for further hypotheses and future research in larger and longitudinal studies to examine treatment responses.

In this case report, trichoscopy was highlighted as a vital diagnostic tool for pediatric alopecia areata, showing significant hair regrowth in a 4-year-old girl with toxoplasma-related alopecia after six weeks of therapy, emphasizing its role in tracking therapeutic progress.

This case series reports three novel and atypical morphological patterns of alopecia areata, termed the central sparing, paw, and punctate patterns, highlighting their importance for dermatologists in improving diagnosis and management of the condition.

This preliminary study suggests that Raman micro-spectroscopy can help differentiate basal cell carcinoma from hair follicles in skin tissue sections, although some misclassification of hair follicles as carcinoma was observed.

This study found that trichoscopy is crucial for distinguishing lupus erythematosus-specific alopecia from alopecia areata, leading to more accurate diagnoses and better outcomes for patients.

This study found that white females with female pattern hair loss had higher hair density in the occipital scalp area, while Asian females had thicker hair diameters in both frontal and occipital areas.

This study concluded that dermoscopy enhances the diagnostic capability for cicatricial alopecia beyond clinical inspection and identified novel dermoscopic features such as blue-grey dots.

This study found that histopathologic features such as a catagen/telogen shift, melanin in fibrous tracts, and small dystrophic follicles can help differentiate alopecia areata from pattern hair loss in the absence of peribulbar infiltrates.

This report introduces Barcelona - TrichoScan as a novel software tool purported to effectively analyze hair growth in patients with androgenetic alopecia or androgenetic effluvium, but it provides no clinical data.

This study found that high-frequency ultrasonography may effectively distinguish different stages of alopecia areata and differentiate it from other scalp conditions.

This article reviews trichoscopic signs of chemotherapy-induced alopecia, including exclamation marks, but reports no new clinical results.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

This study found that while ethnic hair types share a common fibrous keratin structure, variations in keratin-associated proteins and lipids may lead to different macroscopic hair characteristics.
