Histopathology is crucial for accurately diagnosing eruptive vellus hair cysts.

This report describes a 15-year-old male with widespread papules due to middermal epithelial cysts containing vellus hairs, also observed in his brother and father.

This report discusses the accurate diagnosis of atrichia with papular lesions, emphasizing its distinction from alopecia universalis to prevent unnecessary steroid treatment, and presents a case matching APL diagnostic criteria.

This case study discusses a 36-year-old female diagnosed with a facial variant of eruptive vellus hair cyst, confirmed by skin biopsy, and highlights the importance of considering this condition in the differential diagnosis of asymptomatic facial papules.

This study observed that androgen treatment increased ROS production and TGF-β1 secretion in rat hair follicle dermal papilla cells, suggesting that the androgen-induced TGF-β1 is mediated by ROS.

This review discusses the significance of elastic tissue staining in dermatopathology, particularly for diagnosing primary elastic tissue disorders and other skin conditions, but reports no new clinical results.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

This study found that mutations in the hairless gene in mice disrupt hair follicle integrity during catagen, leading to baldness due to disintegrating epithelial structures and loss of normal dermal papilla.

This review discusses various strategies to enhance drug delivery through the skin barrier, highlighting liposomes as promising carriers for increased dermal concentrations in topical therapies, but reports no new research results.

This case report describes an atypical presentation of eruptive vellus hair cysts on the elbows, where standard diagnostic techniques were unreliable due to the loss of cystic structural integrity.

This study observed that pigmented casts are present in various alopecia types but are not specific to any single diagnosis, with distinct morphological features noted in trichotillomania.

This study found that the retinoid all-trans retinoic acid induced a catagen-like stage in human scalp hair follicles, suggesting upregulation of TGF-beta2 as a contributing mechanism.

Adipose-derived stem cells can be transformed into hair-forming cells using specific extracellular vesicles, offering potential for hair regeneration therapies.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

This study demonstrates that inhibiting SFRP1 with the antagonist WAY-316606 enhances hair growth in human scalp hair follicles ex vivo by facilitating Wnt signalling.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

This study found that using gallate-containing formulations like EGCG or tannic acid increased the solubility and controlled release of finasteride in microspheres, enhancing its dermal penetration in pig skin by 10 to 50 times compared to a control.

This study identified a genetic variant in the CTS6 gene associated with a hypotrichosis syndrome, emphasizing the significant role of cystatin M/E in hair and skin health.

This review highlights the promising potential of microemulsions and nanoemulsions in (trans)dermal drug delivery, noting a gap in understanding their distinct mechanisms and composition-related effects on skin permeability, while emphasizing the limited clarity on mesostructures and cosolvent impacts.

Acne in children varies by age and severity, requires a pediatric treatment approach, and may need diagnostic evaluation for underlying conditions.

This case report presents an 8-year-old girl with congenital atrichia, marked by complete hair loss and papular lesions, linked to mutations in the human hairless gene.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

Skin changes throughout life, from development before birth to aging effects like wrinkles, influenced by both genetics and environment.

Dermatologists give better information on pathology forms, hypersensitivity vasculitis is a common skin issue, misdiagnoses can occur, and various skin conditions are linked to loss of elastin or genetic factors.

This narrative literature review examined how linking embryonic development with non-genetic skin anomalies can improve diagnostic accuracy, guide prenatal counseling, and enrich dermatology education by revealing specific vulnerabilities in skin morphogenesis and supporting advances in regenerative medicine.

This review discusses the protective roles of skin-resident immune cells in maintaining tissue homeostasis and facilitating wound healing, but reports no new experimental findings.

This review examines recent advancements in electrospun nanofibers for wound healing applications, but reports no new experimental results, highlighting their potential in sutures, dressings, and skin regeneration.

This review explores how androgens and growth hormone influence the development of terminal hairs and sebaceous glands, attributing variability in hirsutism and acne to differing genetic sensitivities to androgens, but reports no new experimental data.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.
