This study found that eosinophils are a useful diagnostic feature for alopecia areata, especially when the typical "swarm of bees" lymphoid infiltrate is absent, helping differentiate it from trichotillomania.

This review examines the histopathologic features of four common types of noncicatricial alopecia and reports no new clinical results.

This study reports that horizontal sections of scalp biopsies improve the diagnosis of alopecia areata, especially when characteristic inflammatory infiltrates are missing.

This case report describes an atypical presentation of alopecia areata in a 53-year-old postmenopausal woman, which may resemble frontal fibrosing alopecia and complicate diagnosis.

This article reviews the differences between scarring and non-scarring alopecias and describes diagnostic methods but reports no new clinical findings.

This article reviews the genetic and potential environmental factors in alopecia areata's pathogenesis and suggests a polygenic model but reports no new clinical findings.

Early stage bald spots are linked to skin inflammation and damage to the upper part of the hair follicle.

This report describes a rare case of alopecia areata coexisting with primary scarring alopecia, diagnosed through detailed trichoscopic investigation, highlighting the importance of comprehensive examination for accurate diagnosis.

Hair loss treatment caused more hair loss in a man.

Alopecia areata is a common autoimmune condition causing varying hair loss, diagnosed by specific patterns of inflammation around hair follicles, with several treatment options available.

This study found that targeting both hormonal and immune pathways improved treatment outcomes in androgenetic alopecia patients with an under-recognized inflammatory component called PIILIF, which may contribute to treatment resistance.

This study observed various patterns of permanent alopecia in breast cancer patients treated with taxanes and adjuvant hormonal chemotherapy, hypothesizing disruptions in hair follicle cycles due to chemoinflammatory and hormonal factors.

This review discusses rodent models of alopecia areata and suggests they are crucial for understanding the autoimmune mechanisms and potential treatments but reports no new clinical results.

This article describes two cases where essential alopecia was the initial sign of syphilitic infection, examining the clinical and histopathologic features observed.

This case report describes two brothers with an unusual, possibly treatment-resistant inflammatory variant of androgenic alopecia, featuring follicular isthmic lymphocytic inflammation and diffuse central scalp hair loss.

This study found that DPCP treatment led to cosmetically acceptable hair regrowth in 38% of patients with chronic severe alopecia areata, while adding 5% minoxidil showed no significant clinical benefit.

This study found that selective downregulation of CD200 in the bulge area might contribute to unusual bulge involvement in a subset of alopecia areata cases.

This study found that anthralin and mechlorethamine were the most effective therapies among those tested in AA-affected rodent models, providing a basis for further analysis of their mechanisms in Alopecia Areata.

This article discusses the potential for targeted therapies in hair loss by exploring inflammatory and cytokine-mediated processes, but it presents no new clinical results.

This case report describes the first dermoscopic evaluation of alopecia areata-like disease in a dog, where the condition mirrored human cases in terms of clinical presentation and treatment response.

In this study, 75% of alopecia areata patients showed improvement after treatment with 35% trichloroacetic acid, leading the researchers to conclude it is a safe and effective option for treating this condition.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This report presents evidence that alopecia areata incognita may be a possible mechanism of hair loss in patients with Cronkhite–Canada syndrome.

This study found that serum MIF levels were significantly higher in patients with extensive alopecia areata compared to those with mild alopecia areata and healthy individuals.

This case report describes a 29-year-old man with a year-long non-itchy skin eruption and hair loss, with distinct papules and plaques across his scalp, beard, body, and suprapubic regions, but no systemic symptoms or family history of autoimmune disease.

In this study, a 12-year-old intact male wirehaired fox terrier with testicular neoplasia and alopecia universalis was successfully treated for the alopecia using a combination of ciclosporin and ketoconazole, leading to complete hair regrowth.

This study found that trichoscopy is crucial for distinguishing lupus erythematosus-specific alopecia from alopecia areata, leading to more accurate diagnoses and better outcomes for patients.

This report describes a rare case of lipedematous alopecia in a young Caucasian man, a condition primarily seen in African-American females, presenting with specific scalp and histological characteristics.

This case report describes successful hair regrowth after removing a nevus in a patient with perinevoid alopecia and concentric regrowth, which are rare patterns of alopecia areata.

This report presents a rare case where a patient with chronic urticaria developed alopecia areata during azathioprine therapy, accompanied by bone marrow suppression; these effects resolved after stopping the medication, suggesting a possible link between azathioprine and autoimmune activation despite its intended immunosuppressive use.
