This case report identifies a potential new syndrome characterized by trichoepitheliomas and alopecia, which may be associated with myasthenia gravis.

This review discusses recent advances in understanding hair follicle stem cell dynamics and interactions, but it reports no new experimental findings.

This study observed that transgenic mice expressing keratin K10 under bovine K6beta control developed severe oral abnormalities, suggesting keratin composition changes can affect the physiology of epithelial cells, especially in the oral mucosa.

This case study reports on a rare benign skin tumor known as Pilomatricoma in the lower left orbital region of a 32-year-old male, highlighting its characteristic histopathological features and emphasizing the importance of surgical excision for successful treatment and minimal recurrence risk.

This study found that while malignant pilomatricomas maintain some keratin expression patterns seen in benign counterparts, they notably express additional epithelial keratins, potentially influencing tumor calcification.

This study found that Ber-EP4 immunoreactivity is present in specific areas of hair follicles across different stages of the hair cycle, particularly in the secondary hair germ, but not in mature anagen follicles.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

In this research, most cases of mammary and extramammary Paget disease were reported to express PRAME, expanding the understanding of its presence in cutaneous epithelial tumors, though its diagnostic utility is limited by overlap with other conditions.

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.

In this report, two pediatric cases of solitary basaloid follicular hamartoma, a rare benign skin malformation often misdiagnosed, were documented using dermoscopy, highlighting its clinical diversity and the need for accurate diagnosis.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

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.

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 review discusses the development of targeted therapies for basal cell carcinoma that interfere with Hedgehog signaling and reports no new research findings.

This study reports that epidermal neural crest stem cells from dogs (cEPI-NCSC) can generate neural crest derivatives and may offer a new cell-based therapy for canine spinal cord injury, with potential as a model for human treatments.

This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.

This review examines the potential of K18 as a diagnostic and prognostic marker in epithelial-derived tumors, highlighting its specific expression in tumor tissues and interaction with proteins involved in tumor progression, without reporting new clinical findings.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This article discusses the potential for targeted therapies in hair loss by exploring inflammatory and cytokine-mediated processes, but it presents no new clinical results.

In this case report, a 65-year-old man's neck lesion was initially misdiagnosed as benign but later identified as trichilemmal carcinoma, with the authors recommending Mohs Micrographic Surgery as the preferred treatment option for this rare condition.

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.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

Long-standing benign tumors can become cancerous, especially in people with weakened immune systems.

This study found that permanent alopecia can occur after certain chemotherapy treatments and presents as nonscarring hair loss similar to androgenetic alopecia, with specific histological features that could be misdiagnosed without proper clinicopathological correlation.

This case study describes a unique instance of warty dyskeratoma involving two adjacent hair follicles within one lesion.

This review systematically analyzed literature to differentiate desmoplastic trichoepitheliomas from other cutaneous tumors based on clinical, histopathological, and immunohistochemical features but reports no new clinical results.

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

This article discusses a unique case of permanent chemotherapy-induced alopecia in a patient receiving chemotherapy for breast cancer, characterized by a distinctive histologic finding and excludes bone marrow transplantation, but reports no new clinical results.
