This study found that trichoscopy was 73.77% concordant with histopathology in diagnosing patchy alopecia, highlighting its usefulness as a diagnostic tool for conditions like alopecia areata, lichen planus pigmentosus, and discoid lupus erythematosus.

This article reviews various hair abnormalities observable through trichoscopy in conditions like monilethrix, trichorrhexis nodosa, and ectodermal dysplasias, with no new clinical findings reported.

This study described two cases of trichoblastomas in the tactile hair skin of aged house musk shrews, highlighting that their histological structure differs from that in humans and other animals.

Trichoscopy helped diagnose and treat a child's fungal scalp infection by spotting specific hair shapes.

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.

In this study, sweat duct differentiation was found to be a rare feature in trichilemmal cysts, occurring in only 0.97% of cases, and was likely under recognized.

This study reported that genetic changes in trichilemmal carcinoma resemble those in other skin cancers, with TP53 mutations associated with aggressive clinical outcomes.

This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

This report describes a case where a sex reassignment patient on estrogen therapy experienced complete hair regrowth on a previously fully alopecic scalp.

In this case study, a 74-year-old woman improved her scalp hair condition by reducing chronic rubbing, leading to hair regrowth without ongoing abnormalities after behavior modification.

This review summarizes the main trichoscopic findings for diagnosing common hair and scalp disorders, but reports no new clinical results.

This study observed that the thinning and structural abnormalities in monilethrix-affected hair occur at the internodes due to possible periodic dysfunction of the hair matrix, particularly in the cortex.

This study found that keratin 15 expression in trichoepitheliomas and some basal cell carcinomas suggests a link to hair follicle stem cells in the bulge.

This study examined 50 patients with alopecia areata and found that trichoscopy can identify specific patterns, such as white dots in 90% of cases and black dots in 80%, aiding in assessing disease activity and severity without invasive procedures.

This study found that trichilemmal carcinoma shares genetic changes with other skin cancers, suggesting a similar pathogenesis, particularly in those with aggressive clinical courses linked to TP53 mutations.

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.

The document concludes that the trichogram is a useful tool for diagnosing hair loss and suggests semi-organ cultures for practical trichological research.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

In this study, researchers observed that trichoscopy could reliably identify features such as anisotrichosis and signs associated with inflammation and fibrosis in female pattern hair loss, which may aid in assessing disease severity and guiding treatment decisions.

Advanced imaging techniques are crucial for accurately diagnosing Monilethrix, a rare hair disorder.

This article discusses a hypothetical model of androgenic hair trichophore composed of various chemical components, but it reports no new empirical findings; the authors emphasize the model's potential impact on hair cosmetics.

Ingrown hairs are a common feature in scarring alopecias due to follicular damage.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

This study found that dermoscopy improves clinical diagnosis accuracy for trichostasis spinulosa and proposes a new dermoscopic classification with implications for treatment outcomes.

This article discusses monilethrix, a rare human hair dysplasia caused by mutations in hair keratins, but reports no new clinical findings.

This case report describes a rare instance of trichogerminoma with unusually numerous mitotic figures and a higher Ki67 proliferative rate, distinguishing it from previously documented cases.

This report describes a patient with trichothiodystrophy exhibiting both specific hair abnormalities and developmental delay, contributing to the understanding of this rare disorder's clinical presentation.

This study reports two cases of trichoblastic neoplasms with histologic features suggesting they may be distinct, locally aggressive trichoblastic carcinomas separate from basal cell carcinoma.

This case report describes a 19-year-old woman with typical clinical and histopathological findings of trichofolliculoma, a rare hair follicle hamartoma usually located on the face or scalp.

This study reviewed the usefulness of trichoscopy in diagnosing and monitoring alopecia areata, noting that the technique identifies specific hair features like yellow and black dots, which are linked to the disease's chronic nature and treatment response.
