This case report describes a patient with ulcerative colitis who also presented with an atypical clinical aspect of lichen ruber planus, vitiligo, and alopecia areata.

This review examines the literature on autoimmune hair loss disorders, highlighting the collapse of immune privilege and the potential role of neurogenic stress in this process, but reports no new clinical results.

This article discusses various types of primary cicatricial alopecias and reports no new clinical results; it emphasizes the importance of accurate diagnosis for effective management.

Alopecia areata is caused by an immune response, and targeting immune cells might help treat it.

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 study reports the first documented case of a cat with non-thymoma-associated exfoliative dermatitis showing both clinical and histological resolution after treatment with ciclosporin A, suggesting it may be an effective therapy for this immune-mediated condition.

This manuscript reviews the latest understanding of alopecia areata's pathogenesis, highlighting the roles of genetic, immunological, and environmental factors, with a focus on immune responses involving IFN-γ and cytotoxic CD8+ T-cells as key contributors to hair follicle inflammation and function disruption without follicle destruction.

This research explored the roles of various T cell types in chronic alopecia areata, finding that increased severity of lesions and hair loss may be linked to decreased lesional Foxp3+ Tregs, with a notable role for IL-17 and Th17 lymphocytes in the pathological process.

This review discusses current hypotheses about cicatricial alopecia's pathogenesis, including lymphocyte-mediated mechanisms and sebaceous gland defects, and reports no new results, emphasizing the need for systematic research.

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.

In this study, cicatricial alopecias were classified by inflammatory cell type and the researchers highlighted that primary cicatricial alopecia's exact causes remain unknown, accounting for 6% of all hair diseases despite its unclear prevalence.

This review discusses primary cicatricial alopecias, detailing their classification, pathogenesis, clinical features, histopathologic findings, and treatment, without reporting new experimental results.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

This review discusses current and potential treatments for alopecia areata, focusing on immunosuppressive and immunomodulatory approaches, but provides no new clinical results.

This correspondence critiques a previous report advocating finasteride for frontal fibrosing alopecia, arguing that the evidence on its safety and effectiveness is inconclusive, particularly due to methodological limitations.

This study suggests that SOCS3 treatment may effectively inhibit alopecia areata by suppressing CD8+ T cell activity and IFN-γ production.

This study found that immune-mediated destruction of bulge stem cells is a key factor in the alopecia observed in AE mice, suggesting it as a model for studying primary cicatricial alopecias, particularly lichen planopilaris.

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.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

This narrative review discusses the presentation and progression of discoid lupus erythematosus in chronic cutaneous lupus erythematosus and does not report new research findings.

This study found that Ifidancitinib, a JAK1/3 inhibitor, significantly promoted hair regrowth and reduced inflammation in a mouse model of alopecia areata by decreasing pathogenic T cell activity and inducing T cell exhaustion.

This case report describes a 46-year-old male whose alopecia areata preceded and resolved with treatment for stage IVB classical Hodgkin's lymphoma, highlighting AA as a potential indicator of underlying malignancy, although such cases are rare and not well-characterized.

This article discusses a new global consensus on the classification of vitiligo, describing histopathological findings and outlining treatment strategies, but reports no new clinical results.

In this study, researchers observed that a hidden scalp condition could contribute to acne keloidalis nuchae and potentially other primary cicatricial alopecias, impacting their diagnosis and treatment.

This study concluded that rapid thawing during cryoablation enhances neutrophil and lymphocyte infiltration, increases oxidative stress, and induces cell death, resulting in more substantial tissue damage in mice compared to natural thawing.

This article discusses primary cicatricial alopecias, a group of rare inflammatory scalp disorders resulting in permanent hair loss, and reports no new findings.

This article reviews various types of scarring alopecia, detailing their inflammatory characteristics, but presents no new clinical findings.

This article reviews treatment approaches for cicatricial alopecia, describing how medication efficacy varies and suggesting autologous hair transplantation for stable cases; no new clinical data are presented.

This review discusses the pathogenesis and challenges in treating primary cicatricial alopecia, highlighting the need to understand immune protection collapse in hair follicle stem cells; it reports no new clinical results.
