This study details the presence of two types of cysts in rhino mouse skin, with utricles derived from hair canals and deeper cysts from hair root sheath epithelium.

Cortisone may help hair regrow by altering the local environment, with regrowth starting 3-4 weeks after treatment, but its use is not widely recommended.

Keratosis Pilaris Atrophicans causes skin scarring and might be treated with a new synthetic retinoid.

This study found that KRTAP2 proteins predominantly express in the hair shaft cortex of humans, interact with hair keratins, and play crucial roles in hair shaft keratinization.

This article discusses the multifactorial etiopathogenesis of acne vulgaris, highlighting the roles of sebum production, keratosis, bacterial development, and inflammatory mediators, but reports no new clinical results.

This review discusses the role of zinc and its transporters in skin health and disorders, providing an overview without presenting new clinical results.

This book reviews the various types of acne and acneiform conditions, as well as their treatment options, with expert insights from multiple fields.

In this study, researchers observed that loose anagen hair syndrome is an autosomal dominant disorder characterized by abnormal hair follicle structure and premature keratinization, possibly due to signaling and desmosomal component disturbances.

This study reported that antimicrobial and topical retinoid therapies led to significant changes in the lipid profiles of sebaceous follicular infundibulum, with increased triglycerides and ceramide subfractions observed.

Disulfide bonds are crucial for hair structure during keratinization.

This review discusses azelaic acid's mechanisms and uses in dermatology, noting its effectiveness in treating conditions like rosacea, acne, and melasma, but reports no new clinical results.

This study found that acne lesion formation involves early hyperkeratinization and inflammation around hair follicles, creating a self-sustaining cycle that may progressively worsen acne.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

This case study and literature review describe eruptive vellus hair cysts as uncommon, potentially inherited or acquired lesions, associated with other skin conditions, and challenging to treat despite being benign.

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

This letter to the editor discusses an observed case of hair repigmentation linked with etretinate therapy but reports no new research findings.

This study examined the expression patterns of various cytokeratins in the outer root sheath of human anagen hair follicles, noting distinct differentiation patterns and localization of keratin markers.

This case report describes an 89-year-old woman with a recurrent benign proliferating trichilemmal tumor on her back, highlighting its misdiagnosis as a sebaceous cyst and successful excision with free margins.

This study found that glycolic acid treatment reduced oxidative stress and inflammation in UV-induced skin photoaging in rats, promoting collagen recovery and reducing photoaging signs, potentially by inhibiting the PI3K/Akt and NF-κB pathways.

This article discusses promising therapies for perifolliculitis capitis abscedens et suffodiens and reports no new clinical results; management includes isotretinoin and other medications targeting its underlying causes.

This case study describes a rare cutaneous follicular hybrid cyst intimately associated with syringocystadenoma papilliferum, proposing a potential relationship with the infrainfundibulum based on keratin expression.

This case report describes a treatment approach for frontal and temporal alopecia using oral dutasteride, minoxidil lotion, and triamcinolone injections, with hyaluronic acid successfully treating injection site atrophy.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

This case report details a rare instance of malignant proliferating trichilemmal tumour in a 60-year-old male, emphasizing the significance of histochemical and immunohistochemical markers for accurate diagnosis and differentiation from squamous cell carcinoma.

Acne involves increased lipid production and inflammation, affecting skin cell behavior and treatment resistance.

This case report describes an unusual nail tumor termed "onycholemmal horn" in a 77-year-old woman, highlighting its distinct histopathological features and the importance of excisional biopsy for accurate diagnosis.

This review outlines the complex factors involved in acne pathogenesis—including hormonal, genetic, and environmental influences—and describes current comprehensive management strategies, emphasizing both topical and systemic therapies, while also highlighting emerging treatment options and the significant psychological impact of acne.

This report diagnosed a 68-year-old man with comedonal folliculotropic mycosis fungoides based on clinical and histopathological findings, and found pegylated interferon alpha-2a with isotretinoin beneficial in reducing skin lesions.

This research explored the potential of mesenchymal stem cells in developing therapies for tendon, muscle, and skin injuries in horses and sheep, indicating possible benefits in cellular regeneration and repair.

This review discusses the controversial non-inflammatory alopecia known as alopecia X, highlighting its unknown etiology and the variable effectiveness of various proposed treatments, but reports no new results.
