This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

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 study reports various immunophenotypical patterns in apocrine mixed skin tumors, resembling the structures of hair follicles, sebaceous glands, and apocrine glands.

This review highlights the limited research on sebocyte lipid droplets and their proteins despite their role in sebocyte differentiation and potential involvement in skin diseases like acne and alopecia, and reports no new results.

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

This study highlights the positive roles of sebaceous glands in skin health, including lubrication of hair follicles, delivery of antimicrobial lipids and vitamin E, and involvement in vitamin D conversion, contrasting their traditional association with skin conditions like acne.

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 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.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical 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 report presents the first known case of a proliferating hybrid cyst containing both epidermoid and trichilemmal components on the scrotum of a 44-year-old man.

This case report describes a rare instance of multiple sebaceous cysts over the scrotum in a 22-year-old man, highlighting the effectiveness of ultrasound imaging for diagnosis and the need for surgical intervention in severe cases.

This study describes three adult dogs with sebaceous gland dysplasia, reporting that two showed moderate to marked improvement in symptoms with treatment, though ongoing management is required as the condition cannot be cured.

The authors concluded that Lrig1-positive stem cells are essential for sebaceous gland formation in mice, as their ablation led to temporary sebaceous gland disappearance without affecting hair growth.

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 observed that sebaceous gland atrophy in psoriatic lesions correlates with the down-regulation of specific lipid biosynthetic gene modules, potentially affecting hair appearance without damaging follicles.

In this case report, the authors identified that sebaceous gland atrophy, traditionally associated with psoriatic or drug-induced alopecia, can also appear in seborrheic dermatitis, complicating the histopathological evaluation of alopecia biopsies and emphasizing the need to consider seborrheic dermatitis in differential diagnoses.

This study found that Blimp1+ cells from mice can generate sebaceous gland organoids in vitro, which mimic natural gland traits and may aid in studying acne vulgaris.

This study found that follicular acantholysis is a common histopathological feature in pemphigus, with differences in depth between pemphigus vulgaris and pemphigus foliaceus lesions that may aid in diagnosis.

The side gland of Suncus murinus is a good model for studying human sebaceous glands.

This study found that gray mongooses have more numerous and well-developed sebaceous glands compared to domestic cats, suggesting they may benefit from enhanced lipid-derived skin protection.

This report describes two cases of nevus lipomatosus superficialis with the unusual feature of dilated hair follicles, emphasizing the need for precise histopathological diagnosis to differentiate from similar conditions.

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 describes pilar cysts, common dermal cysts often seen in young women, which typically require surgical removal.

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 report describes a rare case of multiple trichofolliculomas on the face, which clinically resembled multiple trichoepitheliomas.

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.
