research Diagnostic Usefulness of a Peribulbar Eosinophilic Infiltrate in Alopecia Areata
Eosinophilic infiltrate is not a reliable indicator for diagnosing chronic alopecia areata.
research Immunohistochemical analysis of T-cell subsets in the inflammatory infiltrates of alopecia areata and its comparison with androgenetic alopecia
This study found that peribulbar lymphocytic infiltration can effectively differentiate between alopecia areata and androgenetic alopecia using T-cell infiltration patterns in skin tissue.
research Histopathology of alopecia areata, acute and chronic: Why is it important to the clinician?
This article discusses the phases and histological features of alopecia areata and reports no new clinical findings; the authors emphasize recognizing these phases for accurate diagnosis.
research Alopecia Areata Incognita and Diffuse Alopecia Areata: Clinical, Trichoscopic, Histopathological, and Therapeutic Features of a 5-Year Study
This study analyzed the features of alopecia areata incognita and diffuse alopecia areata, finding distinct patterns in hair loss regions and trichoscopic signs, and noted a benign course responsive to topical steroid therapy.
research Renbök Phenomenon and Contact Sensitization in a Patient With Alopecia Universalis
This case report describes a patient with psoriasis and alopecia universalis where psoriasis plaques supported hair growth, suggesting cytokine interaction may influence competing immune responses.
research Histopathologic profile of alopecia areata in Indian patients
This study found that in Alopecia Areata, increased non-anagen terminal follicles and peribulbar lymphocytic infiltrate are consistent histological features, even in cases that have progressed to scarring.
research Circumscribed alopecia areata incognita
In this study, two patients with localized hair thinning showed histopathological signs typical of alopecia areata, responding to corticosteroid treatment similarly to classical cases.
research Concomitant presentation of alopecia areata in siblings: A rare occurrence
This article highlights differences in childhood alopecia areata compared to adult cases but reports no new clinical findings.
research Diagnosis: Alopecia areata or not?
This report presents four cases highlighting diagnostic challenges between specific types of alopecia, comparing their clinical and histopathologic features without providing new research findings.
research Sudden onset hair loss and colour change
This case study reports a man with rapid hair thinning, whitening, and sparse beard, linked to an increased proportion of hair follicles in catagen or telogen phase and peribulbar lymphocytic infiltrate.
research ‘Follicular Swiss cheese’ pattern–another histopathologic clue to alopecia areata
The study concluded that a 'Swiss cheese' pattern in hair follicles is a useful sign for diagnosing alopecia areata.
research Alopecia areta: a review
This review outlines the existing understanding of alopecia areata, detailing its autoimmune nature, clinical presentation, histology, and management strategies, with corticosteroids highlighted as the most popular treatment option.
research HISTOPATHOLOGIC FINDINGS OF ALOPECIA AREATA IN VIETNAMESE PATIENTS
This study involving Vietnamese patients with alopecia areata found that histopathological examination is crucial for diagnosis, noting diverse features including peribulbar lymphocytic infiltration and varying hair follicle characteristics across disease stages, with eosinophils and necrosis observed in some cases.
research A patient with diffuse hair loss
This diagnostic discussion reports that diffuse alopecia areata was identified in a patient with diffuse hair loss, based on specific histopathological features observed in a biopsy.
research Non-scarring alopecia in systemic lupus erythematosus patients at the Lagos State University Teaching Hospital: a cross-sectional study of prevalence, pattern, trichoscopy features and histopathological analysis
This study aimed to document and compare the prevalence and characteristics of hair loss in patients with systemic lupus erythematosus, noting the differences in trichoscopic and histopathologic evaluations between those with and without alopecia. Results are not reported.
research Perifollicular inflammation and follicular spongiosis in androgenetic alopecia
This study observed that inflammation in androgenetic alopecia samples was similar to alopecia areata controls, but infundibular and isthmic inflammation were significantly more common in androgenetic alopecia cases.
research Diffuse Alopecia With Stem Cell Folliculitis
This article describes a woman's case of slowly progressive nonscarring alopecia with unique biopsy findings, suggesting the need to reexamine similar cases currently classified as chronic diffuse alopecia areata.
research Syphilitic alopecia
Syphilitic alopecia is a rare hair loss condition in secondary syphilis that looks similar to another condition but can be diagnosed with specific tests and responds to antibiotics.
research Hair Loss after Rhytidectomy
This study identified acute localized telogen effluvium as a potential cause of temporal hair loss following rhytidectomy.
research A comparative study of histopathologic features in alopecia areata and pattern hair loss
This study found that histopathologic features such as a catagen/telogen shift, melanin in fibrous tracts, and small dystrophic follicles can help differentiate alopecia areata from pattern hair loss in the absence of peribulbar infiltrates.
research ‘Follicular Swiss cheese’ pattern - another histopathologic clue to alopecia areata
This study reported that dilated follicular infundibula are a highly useful histopathologic criterion for diagnosing alopecia areata, particularly during its recovery stage.
research A study of the histopathological features of alopecias on transverse sections of scalp biopsies
This study observed that transverse sectioning of scalp biopsies may aid in diagnosing different types of alopecia by revealing distinct histopathological features like follicle miniaturization and specific inflammatory patterns.
research Alopecia Areata Universalis After Phenobarbital-Induced Anti-Convulsant Hypersensitivity Syndrome
This report describes a rare case of alopecia areata universalis developing in a child during the recovery phase of phenobarbital-induced anti-convulsant hypersensitivity syndrome, which suggests a mechanism involving lymphocyte-related immune responses.
research The Contributory Roles of Th17 Lymphocyte and Cytotoxic T Lymphocyte at the Hair Bulge Region as Well as the Hair Bulb Area in the Chronic Alopecia Areata Patients
This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.
research Frontal Fibrosing Alopecia Involving the Limbs Shows Inflammatory Pattern on Histology: A Review of 13 Cases
This study found that limb hair loss in frontal fibrosing alopecia is inflammatory and permanent, but lacks the classic scarring features seen in scalp alopecia, prompting potential misdiagnosis as alopecia areata.
research Topical Mechlorethamine Restores Autoimmune-Arrested Follicular Activity in Mice with an Alopecia Areata-Like Disease by Targeting Infiltrated Lymphocytes
This study found that mechlorethamine restored hair growth in mice with alopecia-areata-like disease by eliminating infiltrated lymphocytes and inhibiting certain pro-inflammatory cytokines in treated skin areas.
research Alopecia areata but not androgenetic alopecia is characterized by a restricted and oligoclonal T-cell receptor-repertoire among infiltrating lymphocytes
This study observed that patients with alopecia areata often have a T-cell receptor repertoire in skin lesions that suggests a specific antigen-driven immune response may be important in the disease's pathogenesis.
