This study found that trametinib and vemurafenib increased sebum production and gene expression related to lipid accumulation in hamster sebocytes, which may help explain certain side effects in patients.

This study found a significantly higher density of Demodex mites in sebaceous hyperplasia lesions compared to controls, suggesting a possible link between Demodex and the development of these skin lesions.

This study found a significant reduction in the number and size of sebaceous glands in psoriatic skin lesions, indicating potential involvement in psoriatic alopecia.

This study found that keratin K17 is induced in the suprabasal layer of psoriatic scalp epidermis during epidermal hyperproliferation, suggesting it is not specific to hair follicles.

This article reviews the aging process of sebaceous glands, highlighting the role of intrinsic and extrinsic factors on their degradation and reporting no new clinical findings.

In this histopathology study of nevus sebaceus, researchers observed distinct epidermal, sebaceous, follicular, and apocrine changes, including sebaceous hyperplasia and basaloid adnexal proliferation, which help differentiate it from similar conditions like basal cell carcinoma and trichoblastoma.

This study found that variations in sleep patterns, free testosterone, and 5-alpha-reductase type 1 activity are associated with changes in sebum excretion in women, which may contribute to variability in acne studies.

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

This review identifies sebaceous gland disorders as key indicators of hormonal imbalances, detailing how various hormones affect sebaceous function, and emphasizes a multidisciplinary approach to improve diagnosis and management by integrating endocrine, metabolic, and dermatologic insights.

Excision and laser techniques can effectively treat acne keloidalis nuchae.

This article discusses methods to measure comedogenesis in acne through the presence of microcomedones and reports no new clinical results; the authors outline a skin surface biopsy technique using cyanoacrylate gel.

This study mapped the development of the human pilosebaceous unit in prenatal scalp skin using multi-modal analysis, finding that epithelial-mesenchymal interactions guide cellular fate and validated tissue-patterning through a hair-bearing skin organoid model.

This review discusses recent progress in understanding the cellular mechanisms of sebaceous gland development and maintenance, emphasizing the role of stem and progenitor cells in related skin pathologies, and reports no new results.

This case report describes a 29-year-old Japanese man with follicular mucinosis, suggesting nestin-positive, multipotent hair follicle stem cells may be involved in reticular epithelial degeneration of the outer root sheath.

This study investigated the interdigital glands in sheep, highlighting their apocrine sweat glands' ultrastructural characteristics and positive lectin reaction, but reported no new clinical results.

This review discusses the complex interaction between androgens and hair follicle biology, highlighting the need for a better understanding to improve hirsutism treatments, but reports no new results.

This paper reviews the significance of androgen hormones in hair and skin conditions like alopecia, hirsutism, and acne, and reports no new clinical findings.

This study found that the FOS gene may play a significant role in promoting hair follicle development in Tan sheep, with elevated expression during the Er-mao period.

In this study, the staining properties of two types of cysts, epidermal and pilar, were found to differ, supporting their origins from the epidermis and the trichilemmal hair follicle layer, respectively.

This study found that the co-ablation of C/EBPalpha and C/EBPbeta in adult mouse skin disrupted sebocyte differentiation and epidermal homeostasis, highlighting their critical roles in these processes.

This study found that while epidermal PLCγ1 is not necessary for keratinocyte differentiation in interfollicular epidermis, it is crucial for normal hair and sebaceous gland formation in mice.

This study suggests that eruptive vellus hair cysts often have atypical pathological changes and likely originate from the infrainfundibulum and sebaceous duct based on keratin expression analysis.

This article presents a case of a 45-year-old African American man with firm, hyperpigmented papules and pustules on his cheeks and neck, persisting despite various shaving methods.

This study supports the idea that steatocystoma multiplex is a hamartomatous condition and suggests it may be a variant of eruptive vellus hair cyst, both originating in the pilosebaceous duct.

This research observed that Backhousia citriodora leaf extract effectively reduced sebum production and improved sebum composition across different ethnicities, significantly decreasing skin oiliness and the likelihood of shiny skin when used in a cream applied twice daily for 28 days.

This study found that hair growth is regulated by interactions between epithelial and mesenchymal cells, with various growth factors and hormones influencing different aspects of this process.

This case report describes a 65-year-old man diagnosed with a trichofolliculoma, a benign tumor originating from hair follicles, which appeared as a persistent pore on his cheek.

This case report describes an 18-year-old male with a rare acquired smooth muscle hamartoma on his face, characterized by hyperpigmented plaques and increased hair growth, suggesting a histological overlap with folliculosebaceous cystic hamartoma.

The authors concluded that milia, steatocystoma multiplex, and eruptive vellus hair cysts may be subtypes of multiple pilosebaceous cysts with overlapping histologic features.
