This study examined dermoscopic features in African-American women with different types of alopecia and found that a perifollicular pink blush, potentially indicating inflammation, was common, particularly resolved with anti-inflammatory treatment, suggesting dermoscopy could aid in management.

This study found that alopecia areata is associated with distinct systemic and tissue immune signatures, with macrophages implicated as contributors to hair loss, suggesting potential therapeutic targeting of macrophage activity.

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.

This report describes a case of a patient with metastatic renal cell carcinoma who developed a psoriasiform skin lesion while undergoing immune checkpoint inhibitor therapy.

This study analyzed FAERS data to explore the risk and onset patterns of autoimmune skin diseases associated with immune checkpoint inhibitors, finding a strong association particularly with bullous pemphigoid and emphasizing the need for vigilant monitoring of these adverse effects.

This article is a special issue that reviews current research on the pathogenesis, diagnosis, and treatment of systemic autoimmune diseases, but it does not present new results.

This study suggests that MUC1 expression is significantly higher in follicular mucinoses compared to other dermal mucinoses, particularly in lymphoma-associated forms, indicating its potential as a target for immunotherapy.

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 study observed that cutaneous lymphocytosis in cats is a slowly progressive and relatively benign disease, but predicting individual clinical outcomes from skin lesions was not possible.

In this study, trypsin digestion was found to be a faster and more efficient method than the explant technique for extracting bulge-derived keratinocytes from adult scalp biopsies.

In this study of C3H/HeJ mice, researchers observed that alopecia areata is associated with the expansion of exhausted-memory CD8 T cells in multiple organs, with autoreactive activation not fully explained by known mechanisms, shedding light on the immunological dynamics underlying the condition.

This study found that Imaging Mass Cytometry effectively visualizes multiple biomarkers in alopecia areata, enhancing analysis of immune cell and tissue interactions in hair pathology.

This study reported that the most reliable way to differentiate alopecia areata from androgenic alopecia is by detecting intrafollicular CD3 and CD8 cell density, with CD3 being the most specific and sensitive marker.

This study revealed distinct cellular and transcriptomic differences among various subtypes of cutaneous T-cell lymphoma, particularly highlighting characteristics unique to folliculotropic mycosis fungoides.

This study found that IBA-1-immunopositive macrophages in rat skin during wound healing show varied morphometric characteristics and peak in numbers at 2, 6, and 15 days post-injury.

This study analyzed skin biopsies from human monkeypox virus (hMPXV1) cases and found characteristic pustular stage features, including epidermal necrosis, shadow cell appearance, ballooned keratinocytes, and a dense inflammatory infiltrate, expanding histological knowledge crucial for understanding this disease and related Orthopoxvirus infections.

This review highlights the potential for JAK inhibitors to effectively treat inflammatory and autoimmune skin diseases by targeting the JAK-STAT signaling pathway, advocating for an integrated approach to enhance targeted therapy.

This case study describes a patient with rapidly progressing follicular mycosis fungoides, highlighting its unusual histology and challenges in diagnosing it against cutaneous B-cell lymphoma.

This case report describes a 46-year-old man who developed folliculotropic mycosis fungoides, a form of post-transplant lymphoproliferative disorder, following renal transplantation.

This study suggests that local skin inflammation may enhance the deposition of autoantibodies in the skin, potentially affecting the severity of pemphigus lesions in mice.

This study found that peribulbar lymphocytic infiltration can effectively differentiate between alopecia areata and androgenetic alopecia using T-cell infiltration patterns in skin tissue.

This study reviews the mechanisms and recent findings of immunotherapies for NSCLC, highlighting their potential to improve treatment outcomes and reduce side effects compared to traditional therapies.

This study found that CD44 and CD49d together enhance signaling pathways in lymphocytes in mice with alopecia areata, influencing their activation and function.

This case study suggests that autoimmunity involving cytotoxic CD8+ T cells may link alopecia areata and human T-cell lymphotropic virus-1-associated myelopathy in adult T-cell leukemia/lymphoma patients.

This review summarizes the characteristics of the peri-malignant melanoma stroma, indicating its potential role in early dermal metastatic migration and increased metastasis risk.

This study reported that immunotherapy in cancer patients can lead to skin-related immune adverse events, such as rashes, pruritus, and vitiligo, affecting a substantial proportion of patients.

This study observed that epidermal necrosis and keratinocytic ballooning are consistent histopathologic signs of monkeypox in skin lesions, reinforcing the diagnostic value of histopathologic and immunohistochemical analyses.

This study concluded that heterozygous NFKB2 mutations lead to a distinct and severe form of primary immunodeficiency with early onset, primarily T cell-mediated autoimmunity, and impaired B-cell differentiation.

This report on a case of cutaneous lymphomatoid granulomatosis underscores the pivotal role dermatologists have in its early diagnosis, which could potentially improve the otherwise poor prognosis.
