research Horizontal and Vertical Sections of Scalp Biopsy Specimens from Dermatomyositis Patients with Scalp Involvement
Scalp biopsies from dermatomyositis patients show chronic hair loss without scarring, with mucin and blood vessel changes being very common.
research Diagnostic and Predictive Value of Horizontal Sections of Scalp Biopsy Specimens in Male Pattern Androgenetic Alopecia
Horizontal scalp biopsy sections effectively diagnose and predict MPAA, with follicular density and inflammation impacting hair regrowth.
research A Comparison of Vertical Versus Transverse Sections in the Evaluation of Alopecia Biopsy Specimens
Using both vertical and transverse sections gives a better diagnosis of alopecia than using one method alone.
research Vertical vs. Transverse Sections of Scalp Biopsy Specimens: A Pilot Study on the Comparison of the Diagnostic Value of Two Techniques in Alopecia
Transverse scalp sections are better for diagnosing non-scarring hair loss, while vertical sections are better for a specific scarring hair loss called lichen planopilaris.
research Scalp Biopsy Technique for the Hair Surgeon
Dr. Robert S. Haber concluded that hair transplant surgeons must master scalp biopsy techniques to quickly diagnose and treat hair loss conditions.
research Skin Biopsy
Correct skin biopsy techniques are crucial to avoid misdiagnosis of skin diseases.
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 A Comparative Study of Histopathologic Features in Alopecia Areata and Pattern Hair Loss
The study found certain scalp biopsy features can help tell apart alopecia areata from pattern hair loss even when typical immune cells are not seen.
research Hair Density in African Americans
African Americans have less hair density than whites.
research Tinea Capitis in Adult Women Masquerading as Bacterial Pyoderma
Tinea capitis can be misdiagnosed as bacterial infection in adult women but is treatable with antifungal medication.
research The Expressions of Androgen Receptors and Estrogen Receptors in Bald and Non-Bald Areas of Androgenic Alopecia
Hair loss in androgenic alopecia may be linked to increased local androgen activities, but not to estrogen levels.
research Classification of Hair Diseases
Classifying hair diseases, like alopecia, is difficult and needs more research to understand their causes.
research Follicular Stem Cells in Androgenetic Alopecia
Hair loss in Androgenetic Alopecia is not caused by damage to follicular stem cells.
research Evaluation of Hair Loss
Detailed patient history and physical exams are crucial for diagnosing hair loss.
research A Histologic Review of 27 Patients with Lichen Planopilaris
The conclusion is that certain scalp tissue changes are characteristic of lichen planopilaris, with mucinous perifollicular fibroplasia being a new feature for diagnosis.
research Histopathologic Diagnosis of Multifactorial Alopecia
Some people's hair loss is caused by multiple factors, with the most common being a mix of AGA and CCCA.
research Follicular Swiss Cheese Pattern: Another Histopathologic Clue to Alopecia Areata
Dilated follicular infundibula and increased catagen/telogen follicles are key indicators for diagnosing alopecia areata.
research The Clinicopathological Spectrum of Trichoepitheliomas: A Retrospective Descriptive Study
Trichoepitheliomas can be hard to distinguish from other skin conditions and often start in teenage years.
research A Comparison of Vertical Versus Transverse Sections for the Histopathologic Diagnosis of Alopecias
Transverse sections are better for non-scarring hair loss, vertical sections are better for lichen planopilaris, and either method works for other scarring hair loss types.
research Retrospective Study: The Presence of Malassezia in Feline Skin Biopsies. A Clinicopathological Study
Malassezia in cat skin biopsies may indicate internal cancer.
research Hypopigmentation in Frontal Fibrosing Alopecia
FFA patients have fewer melanocytes and thinner skin compared to others.
research Cutaneous Immunopathology of Androgenetic Alopecia
Inflammation, possibly triggered by a specific bacteria and activated by UV radiation, may contribute to male pattern baldness.
research S1 Guideline for Diagnostic Evaluation in Androgenetic Alopecia in Men, Women, and Adolescents
Guidelines for diagnosing common hair loss include detailed history, clinical examination, and various diagnostic techniques.
research Elastin Staining Patterns in Primary Cicatricial Alopecia
Elastin staining helps assess late-stage scarring alopecia but is not definitive, and clinical diagnosis is still crucial.
research Diagnostic Usefulness of a Peribulbar Eosinophilic Infiltrate in Alopecia Areata
Eosinophilic infiltrate is not a reliable indicator for diagnosing chronic alopecia areata.
research Tinea Capitis in Adults
Adults with persistent scalp issues unresponsive to typical treatments should be tested for the fungal infection tinea capitis to start the right antifungal medication.
research Perifollicular Inflammation and Follicular Spongiosis in Androgenetic Alopecia
Hair loss in both Androgenetic Alopecia and Alopecia Areata is often accompanied by inflammation around hair follicles, but the location and severity of this inflammation varies.
research Are Sunscreen Particles Involved in Frontal Fibrosing Alopecia? A TEM-EDXS Analysis on Formalin-Fixed Paraffin-Embedded Alopecia Biopsies (Pilot Study)
Sunscreen particles were not found in inflamed or fibrotic areas of skin in FFA patients, suggesting no direct link to the disease.
research Can You Diagnose Hair Loss (Non-Scarring Alopecia)
Non-scarring hair loss can be diagnosed with two 4mm punch biopsies, one cut vertically and the other transversely.
