This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

This study found that pilomatricomas exhibit co-expression of hair keratin hHa5 and HOXC13 in lower transitional cells, but lack LEF1 and β-catenin co-expression necessary for canonical Wnt signaling pathway-controlled cortical differentiation.

This review discusses recent findings on molecular changes in cutaneous adnexal tumours and reports novel markers and pathways involved, highlighting the diverse oncogenic drivers and tumour suppressor alterations.

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 case study describes an unusual instance of separate trichoadenoma and melanocytic naevi occurring simultaneously on the face, with the cause of their association remaining uncertain.

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.

This chapter classifies various benign skin tumors and discusses their characteristics, treatment indications, and potential for recurrence, but reports no new clinical findings.

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.

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 observed that benign skin tumors were more common than malignant ones, with squamous cell carcinoma being the most frequent type among malignant tumors.

This study found that in thin cutaneous melanomas, tumor regression is associated with a higher risk of sentinel lymph node involvement.

This study found that skin adnexal tumors are mostly benign, with 98.6% of cases being non-cancerous, and highlighted histopathological examination as essential for accurate diagnosis and management, given their frequent clinical misdiagnosis.

This case study reports a near-complete response of a proliferating trichilemmal tumor to neoadjuvant radiotherapy in a 79-year-old woman, highlighting radiotherapy's role in managing this condition when patients are unsuitable for surgery.

This study identified a genetic locus associated with rhabdomyosarcoma susceptibility in mice and found that specific differentiation markers are linked to the regression of basal cell carcinoma.

This case report highlighted the rarity and diagnostic challenges of a giant solitary trichoepithelioma occurring on the neck, noting that while typically benign, these tumors can rarely transform malignantly into basal cell carcinoma.

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.

This case report describes how personalized treatment based on Encyclopedic Tumor Analysis successfully led to durable regression in a woman with advanced pilomatrical carcinoma, unresponsive to standard care.

In this study, the authors emphasize that IFK, though rare in young patients, should be considered when diagnosing scalp lesions in all age groups, highlighting the importance of recognizing its dermoscopic and histopathologic features to avoid misdiagnosis and ensure proper management.

This article reports a case of late onset linear and unilateral basaloid follicular hamartoma in an elderly male, highlighting the clinical presentation, histopathological findings, and planned treatment approach.

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.

Cylindromas likely originate from hair follicle stem cells, not sweat glands.

This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

This case report presents the first documented instance of basal cell carcinoma and cutaneous leiomyosarcoma occurring as a collision neoplasm in the same biopsy specimen.

In this case report, a rare instance of pilomatrixoma was identified in the left hand of a 40-year-old patient, with successful surgical treatment and no recurrence observed after four years of follow-up.

This report discusses a case of pilomatrixoma, an uncommon benign skin tumor, and emphasizes the importance of histopathological analysis for accurate diagnosis to avoid misdiagnosis as malignancy.

This report presents a rare case of trichoadenoma occurring in the vulva, adding to the limited instances documented in medical literature.

This case report provides the first evidence of clinical and histopathological findings of cutaneous diffuse basaloid follicular hamartomas in a young domestic short hair cat.

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

This review examines the diagnostic significance of yellow and orange colors in skin lesions and concludes that their role is often underrepresented in the literature.

This study indicates that the OVOL1-OVOL2 axis may play a significant role in hair follicle differentiation and growth, potentially serving as therapeutic targets for hair disorders like alopecia and in the tumorigenesis of pilomatricoma.
