Generalized trichoepitheliomas with hair loss may indicate myasthenia gravis.
research Dissecting the bulge in hair regeneration
Stem cells in hair follicles are diverse and change throughout the hair cycle.
research Severe Abnormalities in the Oral Mucosa Induced by Suprabasal Expression of Epidermal Keratin K10 in Transgenic Mice
Abnormal keratin expression in mice causes severe oral issues, affecting feeding.
research Pilomatricoma in the infraorbital region
Pilomatricoma is a rare, benign skin tumor that requires surgical removal for best results.
research Activated Kras Alters Epidermal Homeostasis of Mouse Skin, Resulting in Redundant Skin and Defective Hair Cycling
Activating Kras in mouse skin causes excess skin and hair loss.
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 Ber‐EP4 antigen is a marker for a cell population related to the secondary hair germ
Ber‐EP4 marks cells related to the secondary hair germ in hair follicles.
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 Quisto matrical. Diagnósticos diferenciais.
The skin lesion was diagnosed as a matrical cyst with unusual features.
research Expression Patterns of Gli-1, Pleckstrin Homology-Like Domain, Family A, Member 1, Transforming Growth Factor-β1/β2, and p63 in Sebaceous and Follicular Tumors
The research suggests that p63 and TGF-β1 may help determine tumor type and malignancy in hair follicle and sebaceous tumors.
research Solitary Basaloid Follicular Hamartoma: A Report of Two Cases.
Basaloid follicular hamartoma is a rare, benign skin growth often misdiagnosed.
research The CD44+ALDH+ Population of Human Keratinocytes Is Enriched for Epidermal Stem Cells with Long-Term Repopulating Ability
Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.
research Recent advances on skin‐resident stem/progenitor cell functions in skin regeneration, aging and cancers and novel anti‐aging and cancer therapies
New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.
research Histopathological Findings and Proliferative Activity of Canine Sebaceous Gland Tumours with a Predominant Reserve Cell Population
High proliferative activity and peripheral invasion indicate malignancy in canine sebaceous gland tumors; the term 'epithelioma' should be updated for clarity.
research Alopecia Universalis Associated with Cutaneous T Cell Lymphoma
Some patients with a type of skin lymphoma can experience a rare, non-scarring hair loss that looks like another hair loss condition but has distinct features.
research Activated Hair Follicle Stem Cells and Wnt/β-catenin Signaling Involve in Pathnogenesis of Sebaceous Neoplasms
Abnormal activation of hair follicle stem cells and Wnt/β-catenin signaling contributes to sebaceous neoplasms.
research Basal Cell Carcinoma, Hedgehog Signaling, and Targeted Therapeutics: The Long and Winding Road
New treatments targeting the Hedgehog pathway can help treat advanced skin cancer but may have side effects and their effectiveness in early stages is unknown.
research Canine Epidermal Neural Crest Stem Cells: Characterization and Potential as Therapy Candidate for a Large Animal Model of Spinal Cord Injury
Canine epidermal neural crest stem cells could be a promising treatment for spinal cord injuries in dogs.
research CD99 Is Strongly Expressed in Basal Cells of the Normal Adult Epidermis and Some Subpopulations of Appendages: Comparison with Developing Fetal Skin
CD99 is highly present in certain skin cells and could help treat skin conditions.
research The relationship between keratin 18 and epithelial-derived tumors: as a diagnostic marker, prognostic marker, and its role in tumorigenesis
Keratin 18 helps diagnose and predict cancer progression and affects cancer growth and spread.
research Alopecia: A Pathologist's View
The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.
research Subtle Trichilemmal Carcinoma of Neck Initially Misdiagnosed as Benign Cyst and Ultimately Treated with Mohs Micrographic Surgery
A neck lesion misdiagnosed as benign was later treated successfully with Mohs Micrographic Surgery.
research Scaling dermatosis in three dogs associated with abnormal sebaceous gland differentiation
Three dogs with a rare skin condition improved with treatment.
