The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This paper presents two cases of rare intraorbital ophthalmic artery aneurysms associated with arteriovenous malformations and discusses their clinical presentation, pathogenesis, and management, but reports no new clinical outcomes.

This study found that Hoxc13-/- rabbits exhibit complete hair loss on the head and dorsum, providing a potential model for understanding human ECTD-9 and related dermatological conditions.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This report describes the clinical and histopathological features of lipoid proteinosis in a brother and sister with lid lesions, highlighting the importance of recognizing such lesions for diagnosis.

This study found that Wnt5a regulates hair follicle differentiation in mice by mediating epithelial-mesenchymal interactions and influencing dermal papilla cell activities.

This study found that mutations in the Sgk3 gene cause defective hair follicle development and altered hair cycling in mice, with variable phenotypic outcomes depending on different dysfunction patterns of the SGK3 protein.

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 article reviews hair and nail disorders in children, emphasizing their prevalence, congenital and acquired origins, and the diagnostic challenges compared to treatment, but reports no new clinical results.

This case report details a 65-year-old woman who developed malignant melanoma in her right eye socket following previous eye trauma, treated by orbital exenteration.

Finasteride use during early pregnancy may cause limb deformities in babies.

This study presents two cases correlating the clinical appearance of adult-onset foveomacular vitelliform dystrophy with optical coherence tomography findings, describing the location of the yellow vitelliform material.

This article discusses the association between chronic diffuse telogen hair loss in women and iron deficiency, supporting the view that iron's role is unclear and often overstated, but reports no new clinical results.

This article discusses the late presentation of myotonic dystrophy but reports no new clinical findings.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This study reported that wound-resident mesenchymal cells can be reprogrammed to generate epithelial tissues, aiding in the closure of large, non-healing ulcers without signs of malignant transformation.

This study identified a small population of PAX3+/CD34+ cells in human foreskin tissue that may serve as transition cells between melanocyte stem cells and hair follicle stem cells, characterized by specific marker expressions.

This study found that inhibiting mTORC1 activity with rapamycin increased both hair growth and pigmentation in human scalp hair follicles, suggesting a potential strategy for treating greying and hair loss.

This study found that Manganese PCA, Cinchona succirubra, and Leontopodium alpinum extracts may promote hair growth by enhancing VEGF secretion and activating the Wnt/b-catenin pathway in Human Hair Follicle Dermal Papilla Cells.

This study found that the human hairline is closely linked to several cranial, cerebral, and vascular structures, enabling precise localization of key neuroanatomical landmarks, which could assist in planning neurosurgical procedures.

Hair follicle stem cells and mitochondria are key for hair growth, and targeting their activity could lead to new hair loss treatments.

This study found that hair follicle stem cells, when transplanted in a rat model of ischaemic stroke, migrated to affected areas, expressed neuron-specific markers, and reduced infarct volume, suggesting potential therapeutic benefits.
