This study suggests that the transcription factor Gata6 plays a role in maintaining the structure of the upper hair follicle and may be implicated in conditions marked by its abnormal expansion, such as acne or cystic diseases.

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.

Hair follicles grow hair and release it through the skin.

This case report describes a rare instance of sebaceous trichofolliculoma identified in an 18-year-old boy, characterized by a dermal nodule on the nasal bridge with distinct histological features.

This study found that the transcription factor Gata6 regulates the sebaceous duct lineage identity and plays a crucial role in epidermal wound healing by enabling dedifferentiation and broader lineage capabilities in post-mitotic cells.

This study found HLA and beta 2-microglobulin antigens in various skin structures, with specific localization patterns in keratinocytes and hair follicle components, but not in eccrine or apocrine glands.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

This study observed that lectin-binding patterns in skin appendage tumors reveal differences in sweat gland tumors compared to normal tissues, but pilosebaceous tumors maintained a similar lectin-binding pattern to their corresponding normal structures.

This classification proposal introduces a novel system for categorizing cutaneous adnexal cysts based on their origin in the folliculosebaceous unit and sweat glands, aiming to simplify and enhance understanding of these skin lesions.

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 study describes two new types of dermal keratinous cysts of the eyelids, derived from the pilosebaceous apparatus, each presenting distinct management challenges.

This study found that topical transplantation of green fluorescent protein-labeled bone marrow mesenchymal stem cells significantly improved regeneration of deeper wounds, with increased blood vessel formation, compared to control in a rat model.

This study found that peribulbar lymphocytic infiltration can effectively differentiate between alopecia areata and androgenetic alopecia using T-cell infiltration patterns in skin tissue.

This review revisits mechanisms underlying acne lesion formation and suggests that preventing comedone development requires controlling critical factors in the pilosebaceous follicle before acne involvement.

This review discusses possible mechanisms of SARS-CoV-2 transmission through the skin and sweat and reports no new clinical results, calling for further research on this potential route of infection.

In this study, Dsc 1 was highly expressed in certain layers of fetal epidermis and hair follicle but not in basal cells or oral mucosa, indicating its potential role in maintaining epithelial integrity.

This study found that topical mupirocin resulted in excellent or good treatment responses for feline acne in 24 out of 25 cats, despite some having concurrent dermatophyte or yeast involvement.

This study found that specific histologic features in skin biopsies can help support a diagnosis of traumatic alopecia (trichotillomania), but not all markers are distinct to the condition.

This study found evidence that polythelia pilosa, previously excluded from classification, should be reintroduced as it marks true aberrant mammary structures in men and hirsute women.

This article discusses various types of epidermal nevi and associated syndromes but presents no new research findings.

This review discusses the possible roles of skin and intestinal microbiota in acne pathogenesis and covers related research on traditional Chinese medicine treatments, without reporting new clinical results.

This study found that K6a expression in mouse sebaceous gland ducts correlates with Hedgehog signaling, suggesting a role in duct fate.

This case report documents the first known instance of an ectopic sebaceous gland and duct within a hair follicle in a 21-year-old male with persistent acneiform eruption.

This study demonstrates that sebaceous gland loss is a common early feature in primary scarring alopecia and suggests that inflammation of sebaceous glands or ducts may contribute to follicular damage.

This article reports no new data; it describes the role of sebum in influencing the skin microbiome and epithelial tissues and discusses its altered composition during transit through the sebaceous duct.

This abstract discusses the classification of scarring alopecia, distinguishing it from secondary scarring alopecia and detailing its subtypes based on inflammation patterns and cells present during the disease's active phase, but reports no new clinical results.

The Naked gene in mice causes abnormal sebaceous glands and disrupts hair follicle organization.

Mutations in Far2 mice cause hair loss due to sebaceous gland issues.

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 canine hair follicle stem cells are located in the isthmus/bulge region of the hair follicle, surrounded by telocytes.
