This proof-of-concept study reported that a new, ultra-fast, one-step immunohistochemistry method improved the interpretation of Mohs surgery slides, particularly for poorly differentiated tumors.

This review summarizes the clinical, dermoscopic, and histopathological features of keratoacanthoma and discusses treatment strategies, emphasizing dermoscopy's role in diagnosis and individualized treatment planning.

This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

This case study in a renal transplant patient observed that eruptive KA-type SCCs exhibited aggressive behavior and genetic expression changes following intralesional chemotherapy, indicating potential caution against routine use of such treatments in similar cases.

This study evaluated krokot extract as a hair tonic and found it to be microbiologically safe, effective at extending and increasing hair weight, non-irritating, and generally well-received in terms of aroma and color when tested on rabbits.

Lack of TrkC receptor delays hair follicle development.

In this study, KY19382 was observed to promote hair regeneration and de novo hair follicle formation in mice by activating Wnt/β-catenin signaling, suggesting its potential as a therapeutic for alopecia.

This study found that overexpression of PKCepsilon in transgenic mice reduced papilloma development but accelerated carcinoma formation in a skin tumor promotion model.

This study found that 2% ketoconazole solution stimulated hair growth significantly in a mouse model, suggesting potential benefits for male pattern hair loss.

ITK inhibitors may effectively treat alopecia areata.

This study found that overexpression of PKCepsilon in mouse epidermis was associated with increased susceptibility to metastatic squamous cell carcinoma, potentially through a mechanism involving tumor necrosis factor-alpha.

In this phase I study, CT-707, a new ALK inhibitor, showed a 77% response rate among Chinese patients with advanced ALK-rearranged non-small cell lung cancer, suggesting clinical effectiveness despite some adverse events like diarrhea and liver enzyme elevation.

This study found that trichoblastic fibroma and basal cell carcinoma cannot be differentiated by cytokeratin expression patterns, while trichoepithelioma lacks CK7 expression, distinguishing it from the other two neoplasms.

In this study, researchers observed that keratoacanthoma exhibits dynamic follicular differentiation throughout its stages, with changes in specific keratin expressions, and regressed lesions showing epidermal rather than follicular characteristics.

This report suggests that TCDD may alter human epidermal stem cell populations by upregulating c-Myc, potentially leading to increased stem cell turnover during chloracne development.

This study found that subthermal CRET treatment increased keratinocyte proliferation and modulated cytokine production, affecting the inflammatory response in human keratinocytes through EGFR and ERK1/2/NF-κB pathways.

In this study, TCDD administered to male rats down-regulated EGF receptor in liver plasma membranes and increased protein kinase activity, suggesting EGF receptor–mediated toxicological effects.

This study found that overexpression of PKCα in mouse epidermis increases expression of specific proinflammatory mediators and induces inflammation but does not significantly affect epidermal differentiation, proliferation, or tumor promotion with TPA.

This study evaluated the effect of 2% ketoconazole lotion for androgenetic alopecia, but the results regarding its effectiveness on clinical appearance remained unclear.

This study identified a radio-resistant population of Krt15+ stem cells in the mouse small intestine that can initiate tumors, suggesting potential targets for colon cancer therapy.

This study suggests that KRTAP2-3 may serve as a novel biomarker to identify cells in the polyaneuploid cancer cell state, which is linked to therapy resistance and poor prognosis in prostate cancer.

In this study, topical inhibition of casein kinase 1 in mice was found to enhance melanocyte precursor migration and eumelanin production, suggesting potential applications for treating vitiligo and graying hair through KitL/c-Kit signaling pathway activation.

This research reports that KCV and its palmitoylated derivatives show strong effectiveness in strengthening hair proteins, indicating their potential for use in advanced hair care products.

This article discusses the human KRT72 wild-type allele's role in hair formation and reports no new research findings.

Krt6a-Cre transgenic mice help study gene effects on hair follicle development and tumor suppression.

This review investigates laser-induced Koebner-related reactions and highlights how different laser types, targets, and session frequencies affect the development of these skin responses, particularly in individuals with darker skin phototypes.

In this study, kartogenin promoted hair growth by enhancing cell proliferation and migration in vitro and extended hair length in mice, suggesting its potential as a treatment for hair loss.

This research indicates that KCED-1 and KCED-2 effectively induce adiponectin production in human subcutaneous fat, which may promote hair growth on the scalp.

This study observed that cytokeratin 19 expression in cutaneous carcinomas correlates with the grade of squamous cell carcinomas, with more expression in higher-grade SCCs.

This case report describes a unique instance of keratoacanthomas developing within a red ink tattoo on a 51-year-old male, eight years after tattoo placement, and highlights the importance of monitoring for these lesions in tattoos, particularly red ink.
