900-930 / 1000+ resultsresearch Ultrastructural characteristics of trichilemmal cysts: report of two cases
Trichilemmal cysts may form from hair follicle outer root sheath growth.
research Horn With Miliary Calcification in Squamous Cell Carcinoma
A unique case of skin cancer showed unusual calcification, possibly linked to calcium-binding proteins.
research Aggressive Squamous Carcinomas of the Scalp
Aggressive scalp squamous cell carcinomas have a high death rate and need early, strong treatment.
research Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
research Trichostasis Spinulosa
The study found clear differences in lesion distribution and microscopic features among trichostasis spinulosa, keratosis pilaris, and eruptive vellus hair cysts.
research Suprabasal change and subsequent formation of disulfide-stabilized homo- and hetero-dimers of keratins during esophageal epithelial differentiation
Keratins K4 and K13 form stable dimers in mature esophageal cells, aiding cell stability.
research Patterns of expression of trichocytic and epithelial cytokeratins in mammalian tissues. I. Human and bovine hair follicles
Human and bovine hair follicles have distinct cytokeratins specific to hair-forming cells.
research Tumor suppressor identity can contribute to heterogeneity of phenotype in hair follicle stem cell‐induced squamous cell carcinoma
The type of tumor suppressor affects the form of skin cancer from hair follicle stem cells.
research Expression patterns of hair and epithelial keratins and transcription factors HOXC13, LEF1, and β‐catenin in a malignant pilomatricoma: a histological and immunohistochemical study
The malignant pilomatricoma showed strong epithelial keratin expression, suggesting it may not calcify.
research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research Histochemistry of the porcine pilosebaceous unit
Porcine and human pilosebaceous units are very similar.
research Ultrastructural abnormalities in the dermal papillae of both lesional and clinically normal follicles from alopecia areata scalps
Alopecia areata affects hair follicle structure, even in non-balding areas.
research Models for Skin Cancer
Malignant melanoma is the deadliest skin cancer, while BCC is the most common but rarely spreads, and SCC is more aggressive than BCC.
research Keratoacanthoma of the lip: A case report with emphasis on histogenesis
Keratoacanthomas on lips may originate differently than those on skin.
research Basal Lamina Changes During Tissue Interactions in Hair Follicles—An In Vitro Study of Normal Dermal Papillae and Vitamin A-Induced Glandular Morphogenesis
research Cytokeratins as Markers of Follicular Differentiation
TB and BCC tumors show similar follicular differentiation patterns.
research Keratinisation status and cytokeratins of the human Meibomian gland epithelium
Hyper-keratinisation in Meibomian glands contributes to gland dysfunction.
research The Fate of Epidermal Tight Junctions in the stratum corneum: Their Involvement in the Regulation of Desquamation and Phenotypic Expression of Certain Skin Conditions
Tight junctions help control skin shedding and may be targets for treating certain skin conditions.
research 663 Squamous Cell Carcinoma of the Scalp Following Synthetic Hair Transplantation: A Case Report
Synthetic hair transplants can lead to skin cancer on the scalp.
research Gutartige epitheliale Neubildungen in der Haut des Hundes
Benign epithelial tumors in dogs don't spread or become cancerous.
research Rat Hair Follicle Dermal Papillae Have an Extracellular Matrix Containing Basement Membrane Components
research No evidence for follicular keratinocyte hyperproliferation in acne lesions as compared to autologous healthy hair follicles
Acne lesions don't show increased keratinocyte growth compared to healthy hair follicles.
research 5a Trichoepithelioma
Trichoepithelioma and desmoplastic trichoepithelioma have distinct features that can be identified using reflectance confocal microscopy.
research Progeny of Lgr5-expressing hair follicle stem cell contributes to papillomavirus-induced tumor development in epidermis
research Canine hair‐follicle keratinocytes enriched with bulge cells have the highly proliferative characteristic of stem cells
Canine hair follicles contain stem-like cells with high growth potential.
research Structural features and sites of expression of a new murine 65 kD and 48 kD hair-related keratin pair, associated with a special type of parakeratotic epithelial differentiation
A new pair of mouse keratins, 65 kD and 48 kD, are found in specific skin areas and are linked to a unique skin differentiation type.
research Rapidly growing hand nodule
A 69-year-old woman has a fast-growing hand lesion that didn't improve with salicylic acid.
research The Formation of Vellus Hair Follicles from Human Adult Epidermis1
Adult human skin can grow new fine hair follicles after a deep exfoliation treatment.
research Squamous cell carcinoma arising within folliculitis decalvans
Chronic scalp inflammation can turn into cancer, so regular check-ups are important.
