810-840 / 1000+ resultsresearch Giant pigmented tumour of the scalp—a diffuse neurofibroma or a congenital naevus showing neurofibromatous changes? Immunohistochemical and electron microscopic studies
The tumor likely shows dual neural crest differentiation.
research Multiple pigmentierte Basaliome im Capillitium bei Myotonia dystrophia Curschmann-Steinert
A woman with myotonic dystrophy had multiple skin tumors on her scalp, suggesting a genetic link.
research Pilomatricoma can differentiate not only towards hair matrix and hair cortex, but also follicular infundibulum, outer root sheath and hair bulge
Pilomatricoma can develop into various hair-related structures.
research Skin tumors with matrical differentiation: lessons from hair keratins, beta‐catenin and PHLDA ‐1 expression
Matrical tumors share a common growth mechanism involving the Wnt pathway and consistent PHLDA1 expression.
research Vascular endothelial cells as signaling niches for epithelial stem cells in the skin
Vascular endothelial cells may significantly influence skin stem cells, but more research is needed.
research Pathologic Quiz Case: An 84-Year-Old Woman With a Skin Cyst Containing Ziehl-Neelsen–Positive Structures
Basal cell carcinoma may originate from vellus hair cysts.
research Expression of the hair stem cell-specific keratin 15 in pilar tumors of the skin.
K15 staining helps distinguish basal cell carcinoma from trichoepithelioma.
research Abstract 10845: Spontaneous Coronary Artery Dissection as the Primary Presentation of Ana-Negative Lupus
SCAD can indicate ANA-negative lupus, especially in women with unusual symptoms.
research Scalp melanoma: Distinctive high risk clinical and histological features
Scalp melanomas are more dangerous and often missed, needing earlier detection.
research Persistent hair growth over a hemangioma in a patient with alopecia areata: A clue to pathogenesis?
research Histochemical observations of lectin-binding sites and keratin distribution in calcifying epithelioma of Malherbe.
Tumor cells in calcifying epithelioma of Malherbe resemble hair follicle cells.
research Scalp Arteriovenous Fistula following Hair Transplantation: A Case Report and Review of the Literature
Hair transplants are usually safe but can rarely cause scalp AVF, which can be effectively treated with surgery or endovascular methods.
research Immunohistochemical staining characteristics of epidermal appendages (hair follicles and eccrine sweat glands) to anti-epidermal keratin antisera
Hair follicles and sweat glands show different keratin staining patterns.
research KERATIN PHENOTYPES IN BASAL-CELL CARCINOMAS OF THE SKIN
Basal cell carcinoma shows keratin patterns similar to hair follicle structures.
research A Prospective Study of Dermoscopic and Ultrastructural Features of Vitiligo-Associated Leukotrichia
The study found that white hair in vitiligo has specific patterns and structures, which vary with the stage of the disease and may be similar to another hair condition.
research Lentivirus-Mediated Expression of VEGF165 in Rat Hair Follicle Stem Cells
Rat hair follicle stem cells can be used to improve blood vessel growth in engineered skin.
research Participation of CD34-enriched mouse adipose cells in hair morphogenesis
CD34+ cells from fat tissue help form hair follicles and blood vessels in skin.
research An immunohistochemical study of the apocrine type of cutaneous mixed tumors with special reference to their follicular and sebaceous differentiation
Apocrine type cutaneous mixed tumors often resemble hair follicles, sebaceous glands, and apocrine glands.
research Single-stage transplantation combined with epidermal stem cells promotes the survival of tissue-engineered skin by inducing early angiogenesis
Epidermal stem cells improve skin graft survival by promoting early blood vessel formation.
research The existence of a linear system consisting of sympathetic endings in rat skin
Rat skin has a linear system of nerve fibers linked to hair follicles and muscles.
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 Leptomeningeal angiomatosis accompanied by hair follicle nevus
A baby had a rare condition with abnormal blood vessels in the brain and unusual skin and hair growth, possibly a new syndrome.
research Temporary radiation-induced alopecia after embolization of a cerebral arteriovenous malformation
Temporary hair loss can occur after brain AVM treatment but usually regrows in 8 weeks.
research Expression and localization of the vascular endothelial growth factor and changes of microvessel density during hair follicle development of Liaoning cashmere goats
VEGF and microvessel density are closely linked and peak during specific hair growth phases in cashmere goats.
research A Woman With Nodules and Depressed Scars
The woman has a skin condition involving nodules, scars, and hair loss.
research Solitary, subcutaneous, fixed, firm, and fast-growing nodule
A man had a non-cancerous, fast-growing skin lump on his arm that was removed with surgery.
research Editors' Picks
Scientists found gene mutations that affect hair loss, skin stem cells, and skin disorders, and identified drugs that may help treat blood vessel and skin conditions.
research Abstract 80
Different levels of shear stress affect where cells move and gather in a 3D-printed model, helping to better understand cell behavior in blood vessels.
research Distinctive histopathologic findings in linear morphea (en coup de sabre) alopecia
The study found unique skin changes in a rare type of alopecia linked to a skin condition called linear morphea.
