This case study reports a rare instance of a virilizing androgen-only secreting adrenal cortical adenoma in a 13-year-old, with symptom resolution after surgical removal.

This study found that angiogenin is expressed in human dermal papilla cells, where it might stimulate hair growth by promoting cell proliferation and local skin angiogenesis.

This study found that androgen/androgen receptor signaling accelerates premature senescence in dermal papilla cells, highlighting a potential target for treating androgenetic alopecia.

Loose anagen hair syndrome causes easily shed hair but usually improves with time.

This narrative review discusses the hormonal control of hair growth, particularly focusing on dihydrotestosterone and its role in the pilosebaceous unit and androgen-related hair conditions, and does not report new findings.

This review discusses the physiological process of adrenarche, its impact on behavior and skeletal maturation, and its variability across sex and race, but reports no new clinical results.

In this study, mouse models with EGFR deficiency showed that disrupted hair follicle cycling leads to increased mast cell numbers and inflammation, suggesting EGFR's role in managing hair cycle transitions and preventing folliculitis.

In this study, using a mouse model, researchers found that inducing senescence in hair follicle stem cells led to hair regeneration failure and sebaceous gland enlargement, akin to androgenetic alopecia features.

This review discusses potential links between early-onset androgenetic alopecia and exposure to endocrine disruptors in adolescents, but reports no clinical results; the authors suggest further investigation.

This case report describes an unusual instance of eruptive syringomas in a 25-year-old man, persisting for about 10 years, which is atypical given the patient's sex and the condition's usual presentation.

In this study, researchers found that oestrogen did not increase adrenal androgen secretion in children with premature adrenarche or in adolescents with gonadal dysgenesis undergoing oestrogen replacement therapy.

This study found that continuous β-catenin signaling in adult mouse epidermis can reprogram hair follicles to form benign tumors, which regress after the signaling is discontinued.

This document details the usage policy for full-text reproduction from Durham E-Theses, providing guidelines for personal, educational, and non-commercial purposes without altering the text.

This study found that the androgen precursors DHEA and androstenedione stimulated androgen-sensitive parameters in the sebaceous glands of the skin in castrated male hamsters.

The researchers reported that DHT may reduce the inflammatory responses induced by C. acnes in androgen-sensitive human sebocyte cells, suggesting a potential link between androgens and infection in sebaceous disorders.

In this case study, researchers reported a 61-year-old postmenopausal woman with virilizing symptoms like hirsutism and voice deepening was found to have an androgen-secreting adrenal tumor, emphasizing the importance of considering this diagnosis in similar cases.

This study suggests that cutaneous lymphadenoma is a distinct benign lymphoepithelial tumor characterized by androgen receptor expression, hair follicle stem cell markers, and common EGFR gene mutations.

This research consisted of a Phase I/II study on androgenetic alopecia where male participants received intradermal injections of HSC, with hair growth efficacy assessed through Trichoscan imaging, although no new clinical results are reported.

This article discusses telogen effluvium, a condition where a large number of scalp hairs prematurely enter the shedding phase, and reports no new clinical results; the authors emphasize the range of potential underlying causes.

In this study, researchers observed that the sebaceous gland niche in mice allows for Wnt-induced hair follicle differentiation, unlike the non-permissive bulge.

This article discusses therapeutic options for managing androgenic alopecia but reports no new clinical results, recommending selective and safe drugs such as growth stimulators and DHT inhibitors.

This research observed that during the catagen phase, the inner root sheath of hair follicles becomes an early target, highlighting its potential role in maintaining hair follicle homeostasis.

This study found that the prevalence of the exogen phase was negligible in women with androgenetic alopecia and telogen effluvium, with exogen accounting for a small percentage of hair in both conditions.

The study suggests that abnormal activation of hair follicle stem cells and Wnt10b/β-catenin signaling may contribute to the development of sebaceous neoplasms.

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 found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.
