This article discusses various hair and nail abnormalities linked to paraneoplastic conditions and cancer treatments, emphasizing their potential role in diagnosing and managing internal malignancies and reports no new clinical findings.

This study in female beagle dogs found that long-term exposure to oral contraceptive steroids resulted in significant reproductive and mammary gland changes, with the relevance to human tumor risk remaining uncertain.

In this study, activation of oncogenic K-ras in a mouse model caused the oral mucosa to rapidly progress from squamous hyperplasia to carcinoma within 14 days, demonstrating its acute sensitivity.

This study determined that the incidence of Discoid Lupus Erythematosus at the Government General Hospital, Chennai, from 2006 to 2008 was 1.7 per 1000, with localized and disseminated forms manifesting distinctive demographic and clinical patterns.

This study found that transgenic mice overexpressing human ATF3 showed hyperplastic and dysplastic changes in epithelial tissues, with a high incidence of oral cancer, suggesting potential oncogenic properties of ATF3.

This study found that feeding norethindrone acetate to albino rats over two years caused various dose-related health effects, such as growth retardation and liver changes, but did not increase overall tumor incidence.

This review discusses the role of skin manifestations as early markers and prognostic indicators of HIV infection in children but reports no new clinical results.

This review discusses how skin lesions and haircoat changes in adult horses can indicate systemic diseases, emphasizing the need for veterinary evaluation, and reports no new clinical findings.

This case report describes a 10-year-old British Shorthair cat with lethargy, weight loss, alopecia, and spontaneous pruritus, revealing severe skin changes upon examination.

In this study, researchers investigated the penetration and cellular responses to nanoplastics in human skin models with compromised barriers, finding that nanoplastics can penetrate the skin, accumulate in cells, and trigger inflammatory responses through specific signaling pathways.

A man with both skin lesions and lung cancer improved quickly with chemotherapy, suggesting the skin condition might be a reaction to immune system injury.

This study demonstrated that the highly divergent WDSV rv-cyclin significantly stimulates eukaryotic cell proliferation, leading to hyperplastic skin lesions in transgenic mice.

This review discusses the significance of elastic tissue staining in dermatopathology, particularly for diagnosing primary elastic tissue disorders and other skin conditions, but reports no new clinical results.

This review concludes that current clinical and preclinical evidence does not indicate oncologic safety concerns linked to photobiomodulation therapy for skin rejuvenation, including no clear evidence of increased cancer risk.

This report is the first to associate Cronkhite-Canada syndrome with multiple myeloma, describing regenerative pseudopolyps in a 58-year-old woman rather than true adenomatous polyps.

In this review, the authors discuss how hair may protect against scalp skin cancer by enabling IL-17-biased immunosurveillance, while hair loss could permit tumor development by reducing this immune protection.

In this review, the authors propose that hair on the scalp may protect against non-melanoma skin cancer by maintaining an IL-17 biased immunosurveillance, with hair loss potentially increasing the risk of skin cancer due to disrupted immune monitoring.

This study suggests that human skin contains distinct fibroblast subsets with unique expression profiles and functions, which can be isolated to investigate their role in skin pathogenesis.

This report describes a neurometabolic disorder linked to gain-of-function variants in the ODC1 gene, characterized by developmental delay, ectodermal abnormalities, and notable facial and neuroimaging features.

This study found that one year of finasteride treatment significantly reduced PSA levels and prostate volume in men with elevated PSA and negative prior biopsy, potentially aiding prostate cancer diagnosis.

In this animal study, rats given high doses of ethynylestradiol showed dose-related estrogenic effects, delayed tumor onset in females, and no overall increase in tumor incidence compared to controls.

This review discusses types of hair loss in elderly women, highlighting diagnostic challenges and treatment limitations, but does not present new research findings.

This review discusses various skin lesions associated with endocrinologic disorders such as Cushing's syndrome and adrenal insufficiency, and it reports no new clinical results.

This study found that β-catenin stabilization in specific mammary epithelial lineages leads to cellular changes and the formation of hyperplastic lesions, revealing its role in initiating mammary neoplastic development.

This review discusses lesser-known concerns in transgender dermatology, including neovaginal issues, neoplastic and autoimmune conditions, and the effects of unapproved injectable substances, but reports no new clinical findings.

This chapter reviews the male accessory sex glands in rats and their responses to hormonal influences, detailing common spontaneous changes and effects of compounds, but it provides no new experimental findings.

This monograph reviews the significant progress in skin biochemistry research over eight to ten years, highlighting key areas and identifying gaps in interpretation.

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.

A 90-year-old woman's hand lesion was a rare, aggressive skin cancer treated successfully with surgery.

This review discusses the distinctive non-infective skin presentations of HIV infection from a dermatological perspective and reports no new clinical findings.
