research Histopathological and Ultrastructural Study of Ectodermal Dysplasia/Skin Fragility Syndrome
The study concluded that PKP1 is essential for skin integrity and hair growth, and its dysfunction causes the symptoms of ectodermal dysplasia/skin fragility syndrome.
research Pathologic Diagnosis of Central Centrifugal Cicatricial Alopecia on Horizontal Sections
Horizontal sections of scalp biopsies are good for diagnosing Central Centrifugal Cicatricial Alopecia and help customize treatment.
research Necrobiosis Lipoidica
Necrobiosis lipoidica may need new criteria for accurate diagnosis due to similarities with another condition.
research Development of a Classification System for Extrinsic Hair Damage: Standard Grading of Electron Microscopic Findings of Damaged Hairs
Researchers created a standard system to grade hair damage using microscopic images.
research Basal Cell Carcinoma With Matrical Differentiation: Expression of .-catenin and Osteopontin
Basal cell carcinoma with matrical differentiation is a rare type linked to hair follicles, with .-catenin important for its development.
research Follicular Density and Ratios in Scarring and Nonscarring Alopecia
Nonscarring alopecia has higher hair density than scarring alopecia, and hair density can help diagnose the type of alopecia.
research Histopathology of Hypotrichosis with Juvenile Macular Dystrophy
The research found that a specific gene mutation causes fewer hair follicles and disrupted hair growth cycles, leading to thin and short hair in people with Hypotrichosis with Juvenile Macular Dystrophy.
research An Investigation of Apoptosis in Androgenetic Alopecia
Apoptosis contributes to hair loss in androgenetic alopecia.
research Acquired Localized Longitudinal Pachyonychia and Onychomatrical Tumors: A Comparative Study to Onychomatricomas (5 Cases) and Onychocytic Matricomas (4 Cases)
Larger nail cavity sizes suggest benign tumors, while smaller ones may need further biopsy to rule out cancer.
research Pachyonychia Congenita-Associated Alopecia. A Microscopic Analysis Using Transverse Section Technique
PC-associated alopecia has unique microscopic features.
research Pigmented Casts
Pigmented casts are common in several hair loss conditions and can help diagnose specific types of alopecia.
research Diffuse Alopecia With Stem Cell Folliculitis
Lymphocytes may hinder hair stem cells, causing hair loss without scarring.
research Demodex Folliculitis of the Scalp: Clinicopathological Study of an Uncommon Entity
Demodex mites rarely cause scalp infections leading to hair loss, but when they do, treatment is effective.
research Syndrome of Birt–Hogg–Dubé, a Histopathological Pitfall With Similarities to Tuberous Sclerosis
Birt–Hogg–Dubé Syndrome requires genetic testing for accurate diagnosis due to its similarities with tuberous sclerosis.
research Elastic Staining in Differentiating Between Follicular Streamers and Follicular Scars in Horizontal Scalp Biopsy Sections
EVG staining helps tell apart follicular scars from follicular streamers, aiding in diagnosing different types of hair loss.
research Special Stains and Immunohistochemical Stains in Hair Pathology
Special and immunohistochemical stains are not routinely needed for diagnosing hair disorders.
research Adenolipoma—Eccrine and Apocrine Variants With Evidence for a Hamartomatous Process
Adenolipomas may develop from gland entrapment by fat tissue, showing complex and varied forms.
research Dickkopf-1 Expression in Androgenetic Alopecia and Alopecia Areata in Male Patients
DKK-1 gene linked to hair loss in AGA and AA patients; more research needed for potential therapy.
research Histopathologic Findings of Cutaneous Hyperpigmentation in Addison Disease and Immunostain of the Melanocytic Population
The study found increased skin pigmentation and variable melanocyte density in a patient with Addison's disease.
research Molluscum Contagiosum in an Epidermoid Cyst
Molluscum contagiosum can occur in epidermoid cysts, especially with prolonged steroid use.
research Differentiation and Apoptosis in Pilomatrixoma
Pilomatrixoma involves abnormal hair keratin production and cell death, causing debris and cysts.
research Nail Matrix Pathology in Cronkhite–Canada Syndrome: The First Case Report
Inflammation may cause nail issues in Cronkhite–Canada Syndrome.
research Eccrine Duct Dilation as a Marker of Cicatricial Alopecia
Enlarged sweat gland ducts may indicate scarring hair loss.
research Alterations in Hair Follicle Morphology and Hair Shaft Production After Follicular Unit Transplantation
Hair transplants can make hair follicles larger and hair shafts thicker.
research Punctate Follicular Porokeratosis
Punctate follicular porokeratosis is a skin condition with specific features seen in hair follicles.
research Cutaneous Keratocyst and Steatocystoma Unified as Sebaceous Duct Cyst, a Hamartoma Resembling the Sebaceous Duct
Cutaneous keratocyst and steatocystoma should be called "sebaceous duct cyst" due to their similarities.
research Pili Trianguli et Canaliculi Is a Defect of Inner Root Sheath Keratinization
The hair defect is due to abnormal inner root sheath keratinization.
