Background: The identification of circulating potential biomarkers may help earlier diagnosis of breast cancer, which is critical for effective treatment and better disease outcomes. We aimed to study the role of circ-FAF1 as a diagnostic biomarker in female breast cancer using peripheral blood samples of these patients, and to investigate the relation between circ-FAF1 and different clinicopathological features of the included patients.
Methods And Results: This case-control study enrolled 60 female breast cancer patients and 60 age-matched healthy control subjects.

Anti-vascular endothelial growth factor-associated thrombotic microangiopathy (aVEGF-TMA) was recently discovered in patients with malignant tumors. Four aVEGF-TMA patients diagnosed by renal biopsy between 2018 and 2022 were identified, and all were females aged 30-62 years (mean age, 47 years). Two patients with malignant gastrointestinal stromal tumors who received sunitinib were analyzed.

Introduction: Mixed connective tissue disease (MCTD) patients often have myositis, however, myopathological and clinical data for MCTD are limited. Recent reports have shown that the pathology of MCTD myositis resembles that of immune-mediated necrotizing myopathy (IMNM), whereas earlier reports described perifascicular atrophy or inflammatory infiltrates predominantly in the perivascular region in MCTD myositis. We aim to describe the clinical and myopathological features of MCTD myositis.

Gene fusions involving JAZF1 are a recurrent event in low grade endometrial stromal sarcoma, and have been more recently described in few instances of endometrial stromal sarcoma-like tumors in the genitourinary tract of men. In this article, we describe a previously unreported spindle cell sarcoma harboring an in-frame JAZF1::NUDT5 gene fusion, arising in the chest wall of a 51-year-old man. The tumor had unique morphologic features resembling both endometrial stromal sarcoma and endometrial stromal sarcoma-like tumors, consisting of a mixture of cytologically bland and pleomorphic spindle cells with brisk mitotic activity, within an alternating myxoid and fibrous stroma.

Desmoplastic melanoma is a rare and distinct subtype of cutaneous melanoma, it presents diagnostic challenges due to the lack of specific clinical features and overlapping histopathological characteristics with other malignancies, which necessitate careful clinicopathological correlation and advanced immunohistochemical profiling. While surgical excision remains the cornerstone of treatment, advances in precision medicine, particularly immune checkpoint inhibitors, have shown promise in improving outcomes for unresectable and metastatic desmoplastic melanoma. We present a case study involving a 52-year-old woman misdiagnosed with a malignant peripheral nerve sheath tumor and later identified as desmoplastic melanoma through re-evaluation of histopathological and immunohistochemical findings.
