390-420 / 1000+ resultsresearch A case of localized follicular hamartoma: an ultrastructural and immunohistochemical study
The hamartoma is an abnormal hair growth with limited development in the upper hair follicle.
research Phylloid terminal hair nevus: A unique clinical entity
A baby had a unique skin condition with a pale patch and surrounding dark hairs, not linked to other health issues.
research [Hair follicles and vascular endothelial growth factor].
research Vibrissa hair bulge houses two populations of skin epithelial stem cells distinct by their keratin profile
There are two types of stem cells in rodent hair follicles, each with different keratin proteins.
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 085 Dermal papilla cells control hair follicle matrix keratinocytes proliferation through versican
Versican in dermal papilla cells is crucial for healthy hair growth.
research Clinicopathological insights into the phenotypic variation of autosomal recessive hypotrichosis/wooly hair by c.736T>A LIPH mutation
The conclusion is that the variation in hair thinness in patients is mostly due to the amount of underdeveloped hairs, and treatments that thicken fine hairs might work for those with mild to severe conditions.
research Eruptive Vellus Hair Cysts: A Case and Review of Literature
research The Morphological Basis of vicuña wool: Skin and gland structure in Vicugna vicugna (Molina 1782)
Vicuña wool's quality is due to a high density of fine secondary hair follicles, and their skin glands may be used for communication.
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 Persistent Papular Eruption in a Young Adult: Importance of Histopathology in Diagnosing Eruptive Vellus Hair Cysts
Histopathology is crucial for accurately diagnosing eruptive vellus hair cysts.
research 877 Small T antigen from a folliculotropic polyomavirus activates canonical Wnt/β-catenin signaling in vivo
A virus protein can activate a pathway that may lead to abnormal hair follicle development.
research Absence of vellus hair in the hairline: a videodermatoscopic feature of frontal fibrosing alopecia
Lack of small, fine hair on the front hairline is a key sign of frontal fibrosing alopecia.
research Trichodiscoma. A Benign Tumor Related to Haarschibe (Hair Disk)
research The ultrastructure of the interfollicular epidermis of the hairless (hr/hr) mouse
research 3 Vascular endothelial cells: targets for studying the activity of hair follicle cell-produced VEGF
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 The germinative epithelium of sheep vibrissae and wool follicles has extensive proliferative potential but is dependent on the dermal papilla
Sheep hair follicle cells can grow a lot but need the dermal papilla to do so.
research Eruptive vellus hair cysts: report of a pediatric case with partial response to calcipotriene therapy.
A child with eruptive vellus hair cysts showed some improvement with calcipotriene cream.
research Spatiotemporal secondary hair follicle development in the Lanyu pig (Sus scrofa taivanus): a novel pelage hair follicle model
The Lanyu pig's hair follicles are similar to human ones, making it useful for studying skin healing.
research Trichoadenoma of Nikolowski- A Rare Tumour with Unusual Presentation Over Vulva
A rare hair follicle tumor was found on a woman's vulva.
research Viewpoint 4
Hidradenitis suppurativa may mainly affect vellus hair follicles, not terminal ones.
research Eruptive vellus hair cysts: an original case occurring in twins
Twins had rare skin cysts likely due to genetics.
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 Basal cell carcinoma possibly originates from the outer root sheath and/or the bulge region of the vellus hair follicle
Basal cell carcinoma may start from parts of tiny hair follicles.
research The three-dimensional microvascular and collagen fibrillar arrangements around rat vibrissa hairs as revealed by scanning electron microscopy
The lower part of rat vibrissa hair gets more blood and is well-protected for growth.
