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 study explains how the development of keratin-associated proteins in embryonic epidermis is crucial for forming protective barriers in vertebrates, enabling them to adapt to terrestrial environments.

In this case report, the authors describe a rare cystic panfolliculoma in an 84-year-old man's right conchal bowl, noting its potential to mimic other tumors like basal cell carcinoma, which complicates diagnosis.

This review highlighted that despite existing treatments, chronic nonhealing leg ulcers remain a significant therapeutic challenge, necessitating the development of new methods that are effective, safe, and affordable for patients.

In this study, transitioning a dairy herd from a tie-stall to a free-stall barn improved the health of carpal and hock joints, but increased heel horn erosion and cortisol levels suggested heightened stress.

This article discusses the structure and protective function of pangolin scales, emphasizing their composition of α-keratins and β-keratins, and highlights evolutionary keratin diversification in tetrapods; it reports no new empirical findings.

Stem cells are in deep skin layers, while differentiating cells are in shallow layers.

In this study, a bioengineered construct using a biodegradable polycaprolactone mat cocultured with human keratinocyte and rabbit dermal fibroblast cells demonstrated potential as a tissue-engineered skin substitute, showing good cell adhesion and growth.

This case report identifies hand-foot and stump syndrome as a potential side effect of sorafenib therapy in a 47-year-old man with a leg amputation.

This study describes two new types of dermal keratinous cysts of the eyelids, derived from the pilosebaceous apparatus, each presenting distinct management challenges.

This review highlights that trichofolliculomas can resemble certain skin cancers, emphasizing the importance of recognizing their clinical features to avoid unnecessary surgery; it reports no new clinical results.

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

This study found that overexpression of the intercellular adhesion protein Necl2 in hair follicle stem cells was associated with reduced cell proliferation and delayed wound healing in both cultured cells and transgenic mice.

This case report concludes that the presence of distinctive histiocytic responses in a Cambodian woman's eyelid lipogranulomas suggests surreptitious silicone injections despite her denial of prior procedures.

This case report describes a 65-year-old man diagnosed with a trichofolliculoma, a benign tumor originating from hair follicles, which appeared as a persistent pore on his cheek.

This case report highlights a 34-year-old woman with traction alopecia, where diagnosis was clarified by the presence of peripilar keratin sheaths, a useful dermoscopic clue.

This report presents a rare case of lichen spinulosus in a 52-year-old woman, featuring hyperkeratotic follicular papules and a dense lymphohistiocytic infiltrate in affected skin areas.

This study found that composite skin constructs containing dermal papilla cells promoted better skin healing and hair regeneration in nude mice, highlighting their role in tissue-engineered skin for severe injuries.

This case study reported that reducing glucocorticoids resolved calcinosis cutis in a dog with hypoadrenocorticism, while demodicosis was treated with a fluralaner chewable tablet.

This study found distinct skin surface changes, including faint mosaic melanoderma and atypical scaliness, on long-standing sun-exposed balding scalps that may be associated with actinic field carcinogenesis.

In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.

This case report describes a 26-year-old woman with a giant cell tumor in the left proximal fibula, presenting atypically alongside pseudopseudohypoparathyroidism features, which remain rare in such contexts.

This review discusses the role of neural crest stem cell-like states in adult neural crest-derived tissues, suggesting they may contribute to tissue repair by generating new cell types and activating repair programs.

This essay discusses the role of the nail in mammalian digit tip regeneration and explores whether nail stem cells are solely responsible for this regenerative ability, with no new results presented.

This study suggests that p63 is consistently expressed in the basal cells of the skin and may influence differentiation and the development of common skin carcinomas.

This abstract lists affiliations and states no financial interests but provides no research findings to summarize.

This study reported that transitioning dairy cows from a tie-stall to a free-stall barn significantly reduced carpal and hock lesions, but increased stress and heel horn erosions.

This study found that calretinin immunoreactivity may help identify the innermost cell layer of the outer root sheath in anagen hair follicles and certain cutaneous adnexal proliferations with follicular, sebaceous, and eccrine differentiation.
