This case study found that a skin lesion in a Samoyed dog did not match any single known follicular cyst or neoplasm type described in the literature.

In this study, researchers used 3D bioprinting to successfully create engineered skin tissues with hair follicle-like structures, potentially enhancing skin grafts and safety testing for chemical compounds by more closely mimicking natural skin complexity.

This study found that dermal papilla and sheath cells can induce hair follicle formation in vitro and in vivo by interacting with hair follicle epithelial cells.

This article reviews sPLA2-mediated phospholipid metabolism using sPLA2 transgenic/knockout mice and lipid mass spectrometry, offering insights into the distinct roles of sPLA2 enzymes in various biological events.

This case report describes a 3-year-old boy with atrichia with papular lesions, emphasizing that dermoscopy, showing the 'cluster of stars' appearance, facilitated diagnosis without needing a skin biopsy.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This source describes the development, structure, and types of skin appendage tumors, noting both benign and malignant forms, potential associations with syndromes, and categories based on follicular differentiation.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

In this case report, researchers observed multiple trichofolliculomas in family members, noting this as a rare manifestation of typically singular hair follicle hamartomas.

This review summarizes recent findings on keratins 6, 16, and 17, highlighting their role in keratinocyte behavior and nuclear functions, and discusses their potential as biomarkers for various skin pathologies, including damage, inflammation, and cancer, rather than in healthy skin.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

In this case report, a benign trichoadenoma was identified in a 42-year-old man as a skin-colored nodule on the cheek, with histopathology confirming the diagnosis and differentiating it from similar conditions like pilomatricoma and sebaceous cyst.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This retrospective case series reports on the use of STRAVIX PL, a shelf-stable human umbilical tissue allograft, in managing recurrent pilonidal cyst wounds, suggesting potential benefits in reducing recurrence and providing durable wound coverage compared to traditional methods.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

This study found that deleting the FoxN1 gene in mice disrupted the 3D thymic epithelial structure and led to 2D epithelial cysts, revealing its crucial role in thymus organization but not causing athymia.

This review highlights that skin organoids, advanced three-dimensional models mimicking human skin, are emerging as effective alternatives to traditional culture models and human skin, overcoming limitations of two-dimensional systems and ethical concerns, and are being increasingly used in areas like developmental biology and disease modeling.

This article reviews the steps and methods involved in preparing skin tissues for three-dimensional volumetric imaging, highlighting its potential to provide detailed insights into skin structure not possible with traditional 2D histology, but reports no new findings.

In this study, researchers reported two cases of the rare and benign follicular tumor called panfolliculoma, highlighting its differentiation across all hair follicle components, which is distinct from similar conditions like trichofolliculoma.

This study reported that human induced pluripotent stem cell-derived skin organoids, used to model epidermolysis bullosa, have an epidermal-dermal junction largely lacking type VII collagen, which is important for skin structure.

The document concludes that accurate diagnosis of male and female gonadal disorders is crucial for effective treatment and better patient outcomes.

This paper discusses the role of steroid sulfatase in hormone-dependent tumors and highlights the development of potent inhibitors, noting the commencement of a phase I trial for one inhibitor in postmenopausal breast cancer patients.

This review article discusses ultrasound's potential as a non-invasive tool for diagnosing and treating hair disorders, highlighting its advantages in visualizing scalp structures and enhancing drug delivery, while noting the need for standardized protocols and further research to optimize its clinical application.

This review discusses the crucial role of sex hormones in maintaining and influencing skin health, suggesting ongoing research into hormonal treatments for skin conditions due to life stage changes.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

Treatments for hair loss include estrogen therapy and special shampoos.

This review discusses the regenerative potential of hair follicle stem cell populations and current approaches to reconstructing folliculogenesis for alopecia therapy, but reports no new clinical results.

This review discusses recent findings on molecular changes in cutaneous adnexal tumours and reports novel markers and pathways involved, highlighting the diverse oncogenic drivers and tumour suppressor alterations.

This review discusses the use of lipid nanoparticles for topical and transdermal delivery of pharmaceuticals and cosmeceuticals and reports no new clinical results.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.
