Pleural Rosai-Dorfman disease complicated with renal clear cell carcinoma: a case report and literature review.
Front Oncol
January 2025
Department of Radiology, Daping Hospital, Army Medical University, Chongqing, China.
Background: Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-malignant disorder characterized by excessive proliferation of histiocytes, the cause of which remains unknown. Although the lymph nodes are the most commonly affected site, some patients may present with extranodal involvement, particularly in the skin, nasal cavity, eyes, and bones. In this report, we aim to present a unique case of RDD with pleural involvement in a 61-year-old patient.

Objectives: To assess the prognostic value of Fluorine 18-labeled fluorodeoxyglucose [F]FDG, gallium 68-labeled fibroblast-activation protein inhibitor-04 [Ga]Ga-FAPI-04, C-acetate in hepatocellular carcinoma (HCC) and evaluate the potential usefulness and advantages of different combinations for accurate diagnosis.
Materials And Methods: Thirty-six patients with suspected hepatic masses were prospectively enrolled from May 2021 to September 2022 and underwent [F]FDG, [Ga]Ga-FAPI-04, and C-acetate PET/CT scans before surgery. PET/CT results and histopathologic examinations were independently interpreted by two radiologists and pathologists, respectively.
Antimicrobial Polymer via ROMP of a Bioderived Tricyclic Oxanorbornene Lactam Derivative.

The rapid emergence of multidrug-resistant (MDR) bacteria represents a critical global health threat, underscoring the urgent need for alternative antimicrobial strategies beyond conventional antibiotics. In this study, we report the synthesis of novel biobased antimicrobial polymers bearing quaternary ammonium salts, derived from sustainable feedstocks, maleic anhydride, dimethylaminobenzaldehyde, and furfurylamine. The functional tricyclic oxanorbornene lactam monomer is polymerized via ring opening metathesis polymerization, yielding well-defined polymers with controlled molar masses and low dispersity.

Department of Pathology, Vardhman Mahavir Medical College And Safdarjung Hospital, New Delhi, 110029, India.
Ancient schwannoma is a rare benign variant of schwannoma with marked degenerative changes, often mimicking malignancies, particularly when retroperitoneal and pararenal. A 34-year-old woman presented with a rapidly growing 15 cm retroperitoneal pararenal mass. Imaging suggested an aggressive malignancy.

The sacrum can harbor a diverse group of both benign and malignant tumors, including metastases. Primary tumors of the sacrum can arise from bone, cartilage, marrow, notochordal remnants, or surrounding nerves and vessels. Among a variety of primary tumors of the spine, chordoma, germ cell tumors and Ewing's sarcoma are recognized for their propensity to occur in the sacrum.
