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.

In this study, researchers identified nine cases of hair follicular tumors among 100 dog biopsy samples in Kerala, India, detailing subtypes like trichoblastoma and pilomatricoma, and analyzed their clinical, gross, and microscopic pathology.

In this histopathology study of nevus sebaceus, researchers observed distinct epidermal, sebaceous, follicular, and apocrine changes, including sebaceous hyperplasia and basaloid adnexal proliferation, which help differentiate it from similar conditions like basal cell carcinoma and trichoblastoma.

This case report highlighted the rarity and diagnostic challenges of a giant solitary trichoepithelioma occurring on the neck, noting that while typically benign, these tumors can rarely transform malignantly into basal cell carcinoma.

This source describes the development, structure, and types of skin appendage tumors, noting both benign and malignant forms, potential associations with syndromes, and categories based on follicular differentiation.

This case report provides the first evidence of clinical and histopathological findings of cutaneous diffuse basaloid follicular hamartomas in a young domestic short hair cat.

This case report describes a rare instance of trichogerminoma with unusually numerous mitotic figures and a higher Ki67 proliferative rate, distinguishing it from previously documented cases.

Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.

This report describes a unique benign neoplasm on the nail unit called onychoblastoma, which histologically resembles a trichoblastoma, marking the first documented case of this tumor type.

This study found that magnesium supply significantly influences root hair development in Arabidopsis, affecting reactive oxygen species, calcium signaling, and the expression of genes associated with root hair growth.

This study suggests that low phosphorus and ethylene may influence root hair density through separate pathways, with ethylene manipulation affecting root hair growth in Arabidopsis thaliana.

This study developed mathematical models to simulate phosphate uptake in rice and Arabidopsis, suggesting a phosphate-sensitive repressor could regulate PHO2 mRNA levels, and highlighting potential targets and traits for improving phosphorus-use efficiency.

This study observed that canine follicular tumors are an uncommon type of skin neoplasia in Croatian dogs, often benign but with a small percentage presenting malignancy, and vary based on the breed's hair growth type.

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.

In this study, trichostasis spinulosa was observed in 51 patients with lesions on the nose, where some follicles contained up to 86 hairs each, possibly influenced by endocrine factors and actinic rays.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

This case report details the immunohistochemical study of cytokeratins in a trichofolliculoma, providing insights but no new clinical findings.

This study found that trichocytic cytokeratins, typically found in hair, are also present in nails, filiform papillae of the tongue, and the epithelial reticulum of the thymus.

This abstract provides no results; it is a website notification about cookies and general access to JAMA content.

This study found that trichostasis spinulosa was present in some seborrheic keratoses, indicating they may partly originate from hair follicle cells.

In this study, trichocytes were shown to have potential for alternative differentiation, with mesenchymal cell influences playing a critical role in determining this process.

This study successfully developed and characterized a monospecific monoclonal antibody, LHTric-1, that specifically localizes to the pre-cortical region of the hair follicle and can aid research on hair and nail formation.

This study found that keratin 15 expression in trichoepitheliomas and some basal cell carcinomas suggests a link to hair follicle stem cells in the bulge.

This case report describes a proliferating trichilemmal cyst that underwent malignant transformation, with specific keratins identified in the tumor but no epidermal keratin detected.

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 trichothiodystrophic hair shows reduced and disoriented protein deposition in follicles, with both the cuticle and cortex affected, providing localized structural insights into keratin abnormalities.
