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

This case study reported a 15-year-old girl with a nevus sebaceus of Jadassohn, where a secondary neoplasm potentially developed into either pigmented trichoblastoma or pigmented basal cell carcinoma, highlighting the importance of early recognition and evaluation of such lesions for effective management.

This review discusses recent findings related to sebaceous gland conditions, including updated recommendations for screening in sebaceous neoplasms and potential treatments for acne vulgaris, though no new definitive clinical results are reported.

This study found that sex steroid hormone receptors are largely maintained during the transformation of skin appendages to neoplasms, except for androgen and estrogen receptors in sweat and sebaceous gland tumors.

This retrospective study at a tertiary care hospital observed that follicular tumors were the most common type of skin adnexal tumors (42.9%) among 42 analyzed cases, with malignancies making up 7.1% of the cases.

This study found that cellular retinoic acid-binding proteins and fatty acid-binding proteins are dynamically expressed in skin development and respond differently to retinoic acid, β-catenin, and Notch signaling.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

This source describes the development, structure, and types of skin appendage tumors, noting both benign and malignant forms, potential associations with syndromes, and categories based on follicular differentiation.

This review summarizes major surveys on Behcet's disease, highlighting its systemic manifestations, with primary morbidity linked to ocular involvement causing severe vision loss or blindness.

This study found that transient activation of c-Myc in transgenic mice stimulates keratinocyte proliferation and sebocyte differentiation, affecting normal epidermal and hair follicle development.

The document concludes that permanent hair loss conditions are complex, require early specific treatments, and "secondary permanent alopecias" might be a more accurate term than "secondary cicatricial alopecia."

This study found that the distribution of hair keratin family proteins varies in normal scalp hair follicles, which may aid in identifying the origin of hair neoplasms.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

In this case report, an 18-year-old male's cheek lump initially diagnosed as a sebaceous cyst was found to be a pilomatrixoma after surgical excision and histopathological examination.

This study found that calretinin immunoreactivity may help identify the innermost cell layer of the outer root sheath in anagen hair follicles and certain cutaneous adnexal proliferations with follicular, sebaceous, and eccrine differentiation.

The document explains how hair follicles develop, their structure, and how they grow.

This study found that maternal exposure to artificial food coloring additives altered the expression of CYP1A1, various glutathione S-transferases, and VEGF in rat skin, which could influence skin disease development.

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 review outlines the clinical and histopathological features that aid in classifying tumors arising from the folliculosebaceous apparatus and reports no new research results.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

This review discusses the role of signaling networks in sebaceous gland development and disorders, highlighting recent insights from mouse models and cell line studies, but reports no new experimental results.

This review discusses the pathogenesis of common sebaceous gland diseases and their molecular pathways, but it reports no new clinical findings.

This study found that TGF-β1 expression in follicular tumors correlates with differentiation degree and suggests its potential role alongside p63 in differentiating between sebaceous and follicular tumors.

This review discusses various pathologies involving sebaceous glands, primarily and secondarily, but reports no new clinical findings.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

SACUMAN, a rare condition causing hair loss without clear signs, is often misdiagnosed and needs scalp biopsies for accurate detection.

This review discusses the mechanisms by which isotretinoin and hormonal therapy treat acne through their effects on sebaceous glands, reporting no new clinical results.

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.

A rare benign skin tumor showed unusual features of sebaceous and sweat glands, important for correct diagnosis.

In this study, researchers observed that human sebaceous glands can regenerate in a mouse model using transplanted human skin, potentially offering a tool to study sebaceous gland biology and regeneration.
