This article reviews the characteristics, common locations, and causes of epidermoid cysts, noting that surgical excision is the standard treatment, but it reports no new clinical findings.

The document explains how hair follicles develop, their structure, and how they grow.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

This study suggests that fish oil, specifically its components EPA and DHA, play a beneficial role in promoting skin health by supporting epidermal growth and reducing proinflammatory cytokines.

This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This case report describes a rare presentation of nevus comedonicus following the lines of Blaschko, treated with oral isotretinoin and other therapeutic measures, resulting in a reduction of episodic painful cystic lesions.

This case report details the ocular complications of Hutchinson-Gilford Progeria syndrome in a 20-year-old Bangladeshi patient, highlighting symptoms like dry eyes, Meibomian gland dysfunction, and cataracts.

In this pilot study, researchers observed that low-intensity laser radiation at 445±40 nm increased the temperature of gingival tissues in Wistar rats by 8.37°C without exceeding the safety threshold, suggesting potential for clinical trials.

This study found that skin computed tomography may effectively identify epidermoid cysts by revealing features consistent with histopathology, potentially serving as a non-invasive diagnostic alternative to biopsies.

This study found that the HoxC gene cluster is crucial for the development of hair and nails in mice, with key regulation by two mammalian-specific enhancers.

This article discusses the pathogenesis of hidradenitis suppurativa, highlighting follicular occlusion and inflammation as key factors in disease development, but reports no new clinical results.

This study observed that Yuyi hairless mice develop alopecia shortly after birth, with the skin eventually thickening and forming folds, and hair failing to regrow as they age.

This review suggests that the inner root sheath of human hair follicles may have broader regulatory roles beyond structural support, potentially impacting processes like folliculogenesis, anagen phase regulation, and immunomodulation.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.

This research suggests that mouse mutants and genomics can help study hair biology and epithelial differentiation by focusing on the role of the Foxn1 gene.

This source provides a comprehensive review of acne vulgaris, highlighting its pathophysiology, epidemiology, molecular mechanisms, and treatment options, emphasizing the significance of addressing acne's psychosocial burden for adolescents and beyond.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This review discusses the diagnostic criteria and guidelines for managing loose anagen syndrome and differentiating it from non-scarring alopecias, but it reports no new clinical results.

This study found that the distribution of desmogleins is associated with specific types of keratinization and hair anchorage, as well as hypotrichosis.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This review discusses recent advances in understanding acne pathobiology, highlighting the potential for developing new customized therapies, but it reports no new clinical findings.

This article provides a comprehensive review of ichthyoses, including their classification, biochemistry, associated syndromes, and therapeutic approaches, but reports no new clinical findings.

This review examines the histochemistry and keratinization processes of human hair, exploring the structural roles of keratin proteins, protein chains, and lipids, but offers no new results.

This study found that oral isotretinoin achieved good to excellent clinical results in treating severe inflammatory acne, severe rosacea, and gram-negative folliculitis.

This study found that Demodex folliculorum and Demodex brevis mites can cause eyelid follicular and glandular changes, potentially contributing to ocular disease in humans.

This introduction highlights the impact of acne vulgaris on quality of life and the complexity of selecting effective treatments, but it presents no new clinical results.

This study describes five patients with porokeratotic adnexal ostial nevus, a rare skin disorder, highlighting its clinical features and proposing a new encompassing term for related conditions.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

This article presents two cases of keratosis follicularis spinulosa decalvans and reviews its features, highlighting characteristic progression from keratosis pilaris in infancy to cicatricial alopecia in childhood.
