This case report establishes the diagnosis of seborrheic keratosis in an elderly Indian woman based on histopathological examination, highlighting its potential to mimic malignant tumors and emphasizing the importance of differential diagnosis.

This discussion reviews the classification and naming of cutaneous cysts, proposing that cysts typically named cutaneous keratocyst and steatocystoma should be unified under the term "sebaceous duct cyst," but it reports no new clinical results.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

This review discusses the influence of androgens on hair and sebaceous growth, emphasizing that response may depend more on peripheral sensitivity than on hormone levels; it reports no new empirical results.

This study proposes the sebogenic hypothesis, suggesting that hair follicles evolved from primitive sebaceous glands to facilitate lipid transport and improve water retention in early land-dwelling animals.

This study found that trichostasis spinulosa was present in some seborrheic keratoses, indicating they may partly originate from hair follicle cells.

This article reviews the role of androgens in skin metabolism and diseases like acne and androgenic alopecia, but reports no new clinical results; the authors note unresolved issues regarding androgen interactions in skin structures.

This study suggests that the newly characterized sebocytic progenitor cells HSGC1 and HSGC2 from different skin sites may have proliferative and differentiating potential in response to DHT.

This paper discusses the role of androgen hormones in regulating sebum production and hair growth via androgen receptors in the pilosebaceous unit, but reports no new findings.

This study found that the absence of sebaceous glands may be an early factor in the development of keratosis pilaris, leading to hair shaft and skin barrier abnormalities, independent of filaggrin mutations.

In this case report, a 16-year-old African American girl with sebaceous filaments on her face was successfully treated with topical tretinoin, highlighting the importance of recognizing and treating this under-reported condition for improved appearance and quality of life.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This study found that among 120 men, two antidandruff shampoos increased sebum excretion rate, while one shampoo decreased sebum output, highlighting distinct effects on the follicular reservoir.

This study found that SZ95 sebocytes and HaCaT keratinocytes exhibit distinct enzyme expressions and activities, implicating their different roles in androgen metabolism and homeostasis in vitro.

The document concludes that scalp health is influenced by complex factors affecting sebaceous glands, including hormones, aging, and various substances.

This study found that pubic hair from Korean males has a thicker cuticle layer with more scales compared to scalp hair, offering better protection against chemical damage, and hypothesizes this evolved as a defense mechanism against exposure to urine and ammonia.

This review identifies excessive sebum, decreased elasticity, and increased hair follicle volume as key factors contributing to enlarged skin pores, emphasizing the need for individualized treatment based on underlying causes.

This study suggests that both the sebum composition and microbial imbalance on the scalp may play a role in the development of androgenetic alopecia among Japanese males.

This study suggests that artificial sebum L may serve as an effective substitute for human sebum in drug transport studies, due to its similar physicochemical properties.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This review highlights recent findings on the importance of signalling pathways in sebaceous gland morphogenesis and differentiation, but reports no new clinical results.

This study found that both hard and soft selenium disulphide-based detergents significantly increased triglyceride levels in human hair, suggesting enhanced sebum production with reduced lipolytic activity, but showed no significant differences between their effects.

This study found that human meibomian glands differ significantly from free and hair-associated sebaceous glands in morphology and lipid composition, making them highly specialized holocrine glands.

This study found that gastrointestinal dysfunction is a significant risk factor for sebaceous gland diseases in adolescents, with correlations observed between these conditions and various GI symptoms.

Hormones and signaling pathways control sebaceous gland function and could help treat acne.

This case report describes a 19-year-old male with alopecia totalis and comedones over the bald scalp, suggesting the importance of terminal hair for sebum drainage to prevent preliminary acne lesions.

Among cultured sebocytes, this study found that bilobetin significantly inhibited lipid production induced by IGF-1, suggesting potential for use in acne treatment.

This study identified a novel skin site called the follicular epidermis that is prone to cancer, with unique Axin2+ stem cells regulating its homeostasis. The findings suggest current therapeutic approaches may need reconsideration due to new insights into obstruction mechanisms at this site.
