This study observed that amelanotic melanocytes from human hair follicles appeared morphologically immature, suggesting they might not transfer melanosomes into keratinocytes.

In this case study, a 51-year-old Japanese man was diagnosed with desmoplastic trichoepithelioma after histological examination of surgically excised facial plaques.

This case study documented a black male newborn developing large bullae that healed with hypopigmentation, suspecting proteolytic enzymes in keratinocytes caused the collagenolysis responsible for the condition.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This study identifies a mechanism where dsRNA activates TLR3 to induce RA production, promoting hair follicle regeneration in mice and suggesting a potential role in human tissue regeneration.

The hair follicle structure is more complex than thought, with new findings on protein formation.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

Capitate trichomes have more endoplasmic reticulum and vacuoles, while peltate trichomes have more plastids and larger subcuticular spaces.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This study found that keratin intermediate filaments in the hair of patients with giant axonal neuropathy were structurally altered, resulting in hair that was stiffer, stronger, and more extensible.

This article discusses recent findings on piedra infections in hair and their keratinolytic activities, but reports no new clinical results.

This study found that trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.

This article describes a 9-year-old girl with whitish granules on her hair, evaluated in a dermatology clinic, but the abstract does not report a diagnosis or new results.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

This report describes four trichoblastoma cases rich in Merkel cells, suggesting these tumors may mimic fetal skin development where Merkel cells are numerous.

This study investigated pilomatrixoma, a benign skin tumor, and found that irregular expression of β-catenin and Lef-1 in transitional cells may contribute to amorphous debris and cyst formation.

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 study explored the structure and keratin composition of marsupial hairs, finding similarities in keratin localization to hairs in placental mammals, and highlighting potential roles of trichohyalin and transglutaminase during hair development and shedding.

This study observed that the lower part of vibrissa hair roots in adult Wistar rats receives a richer blood supply and structural protection, compared to the upper part.

This study suggests that Rushton’s hyaline bodies form through both epithelial changes leading to hair keratin production and hemorrhage supplying erythrocytic substances, resolving previous debates about their origin.

This study found that NNAT is localized in both undifferentiated and differentiated cells across various rat tissues and has cell-specific intracellular localization, suggesting distinct functional roles.

A man had a non-cancerous, fast-growing skin lump on his arm that was removed with surgery.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.
