AI Article Synopsis
- Retroperitoneal vascular leiomyosarcoma (RVLMS) is a rare and aggressive cancer, highlighted in this study that investigates its diagnosis and treatment experiences at a hospital between 2018 and 2020.
- The authors collected data on four patients, focusing on surgical methods and complications, with procedures tailored to tumor characteristics, resulting in successful operations with some intraoperative blood loss and follow-up observations.
- Findings revealed a high rate of atypical tumor features and recurrences, emphasizing the challenges in diagnosing RVLMS due to its unusual symptoms and imaging characteristics.
Article Abstract
Background: Retroperitoneal vascular leiomyosarcoma (RVLMS) is an extremely rare disease in clinical practice, and it has poor prognosis. This article is to explore the diagnosis and treatment of RVLMS and present our experience.
Methods: Data of RVLMS patients were continuously collected in our hospital from August 2018 to February 2020: two males and two females with a median age of 56 (min-max = 33-61) years were included. Patients in whom paraganglioma could not be excluded were asked to take phenoxybenzamine before surgery. A multi-disciplinary team (MDT) meeting had been held and surgery was recommended. The operation procedures varied based on the tumor location, shape, and stage, and the core steps were "exposure of the retroperitoneum and tumor, identification of vital blood vessels, blocking the bloodstream, complete removal of the tumor and tumor thrombus, and release of blood flow". A Satinsky clamp was used to partially block the blood vessels. Follow-up was conveyed by revisits and phone calls.
Results: One patient underwent open surgery, and three patients underwent laparoscopic surgery, one of whom underwent conversion to open surgery. The procedures were finished successfully, with a median operative time of 314.5 (min-max = 224-467) mins. The median amount of intraoperative bleeding was 550 (min-max = 200-1500) ml, and three patients had transfusion during the operation. The mass was irregular in shape, with a median maximum size of 7.45 (min-max = 4.2-10.7) cm, and the pathological examination confirmed RVLMS, which has spindle-shape, high mitotic activity and atypia. One week after the operation, the median serum creatinine level was 85 (min-max = 70-99) µmol/L. The median follow-up time was 16 (min-max = 13-21) months, and 1 case reported asymptomatic recurrence.
Conclusion: Uncharacteristic manifestations and imaging features contribute to the problematic diagnosis of RVLMS. Comprehensive preoperative evaluation and careful surgical planning are essential. Multicenter research is needed in the future to reach a dominant consensus.

Article Synopsis
- The popularity of atrial catheter ablation has surged as a leading treatment for supraventricular tachycardias, praised for its safety and effectiveness.
- Complications can occur at various stages, including vascular, thromboembolic, and mechanical issues, with atrial fibrillation ablation being notably riskier due to its complexity.
- Strategies to minimize risks involve advanced techniques like optimized anticoagulation and esophageal temperature monitoring, while emerging methods like pulsed-field ablation show promise for improved safety, pending further research.

Paraganglioma, a catecholamine-producing tumor originating in extra-adrenal paraganglion cells, is rare in children. Although diagnosis of paraganglioma is based on the presence of catecholamine symptoms, some patients lack such symptoms. Delayed diagnosis is associated with tumor growth and invasion of surrounding vessels.

The hyaline-vascular variant of Castleman disease (HVCD) is relatively uncommon and demonstrates no specific clinical or laboratory findings; therefore, its preoperative diagnosis warrants a radiological evaluation. This study aimed to review imaging findings of HVCD, focusing on perilesional fat stranding and fatty proliferation. Patients with a pathologically confirmed HVCD diagnosis who had undergone CT were recruited from five hospitals from January 2000 to March 2023.

Erdheim-Chester disease (ECD) is a rare, multisystemic, non-Langerhans cell histiocytic neoplasm predominantly affecting middle-aged males in their fifth to seventh decades of life. It often presents with nonspecific symptoms, leading to a delay in its diagnosis. We report a case of an 85-year-old male with multisystemic manifestations, including retroperitoneal, skeletal, vascular, cardiac, orbital, and central nervous system (CNS) involvement.
