The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

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 abstract contains only journal subscription and informational content and does not present any research findings.

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

This study found that synthetic melanin particles applied topically in mouse injury models improved wound healing, showing potential as a therapy for accelerated healing, including in human skin explants.

This review discusses recent advances in understanding Merkel cell carcinoma biology, including the development of genetically-engineered mouse models and potential therapeutic targets, but reports no new clinical results.

This study found that the development of Merkel cell carcinoma from hair follicles in mice can be driven by in vivo reprogramming with ATOH1 and relies on p53 loss for progression.

This article reviews topics from the American Academy of Veterinary Dermatology and American College of Veterinary Dermatology Annual Meeting and contains no new clinical findings.

In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.

Skin problems like acne, dry skin, and nail and hair changes are common in patients taking EGFR inhibitors.

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 article reviews the identification and assessment of cutaneous drug reactions, emphasizing the importance of early recognition and the need for accurate diagnosis to prevent serious complications; it reports no new clinical results.

Minoxidil showed a 30% success rate for hair growth in a study, and various skin treatments were effective, but some had limitations or side effects.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This article discusses methods for diagnosing and managing diffuse hair loss and reports no new results; the authors emphasize systematic evaluation and the importance of psychological support.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

In this case report, an 18-year-old male with an oral epidermoid cyst experienced trouble swallowing and respiratory distress, but recovered well following surgical removal of the cyst.

This article discusses using cosmetic hair products alongside medical treatments for hair conditions to enhance patient self-esteem and quality of life, without reporting new clinical results.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study found that basal cell epithelioma resembles fetal primary epithelial germ based on specific cellular characteristics.

This study reports that the monoclonal antibody BKN-1 specifically stained basal cell epithelioma cells and certain normal skin structures, indicating a similarity in keratin expression between the tumor and follicular epithelium below the isthmus portion.

This study reported that distinct stem/progenitor populations in the ocular surface epithelium have different cell division frequencies and respond differently to injury, with specific spatial compartmentalization and migration behaviors.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

In this study, rat primary thymic epithelial cells demonstrated a clonogenic growth pattern in vitro and were able to integrate into functional thymus or differentiate into skin derivatives, similar to skin multipotent stem cells.

This dissertation reports that horizontal basal cells in the olfactory epithelium undergo symmetric divisions balanced by population asymmetry, which supports their renewal and differentiation during tissue homeostasis and regeneration.
