Interdigitating dendritic cell sarcoma (IDCS) and retroperitoneal leiomyosarcoma are rare tumors. The optimal diagnosis, treatment and prognosis remain unknown. The current case report presents a 46-year-old male who exhibited with a left renal mass combined with a periprostatic mass. The patient underwent surgery twice, respectively for the resection of the two masses. The postoperative pathological examination confirmed the diagnosis of IDCS presenting in the kidney and retroperitoneal leiomyosarcoma in the pelvis. To the best of our knowledge, it is the first report of IDCS in the kidney and of the combined appearance of IDCS and retroperitoneal leiomyosarcoma in the same patient.

The purpose of this article is to overview the clinical significance of left supraclavicular adenopathy and review the etiology of inferior vena cava (IVC) thrombosis, starting from a presentation of a rare case of renal cell carcinoma (RCCs) with Xp11.2 translocation involving TFE3 gene fusion. This article also aims to review the literature to understand the characteristics of this rare type of renal tumor.

Background: Pulmonary bronchial leiomyosarcoma is an extremely rare malignant tumour of the lung originating from the mesenchymal tissue. The retroperitoneal region is the most common site of leiomyosarcoma. It exhibits a high degree of malignancy and a poor prognosis, thereby highlighting the significance of early diagnosis of this disease.

Introduction And Importance: While the treatment approach for sarcomas seems straightforward and well-defined, we often encounter several diagnostic or therapeutic challenges in clinical practice. This article presents a case of retroperitoneal leiomyosarcoma in a patient with chronic kidney disease, highlighting the complexity of managing such cases.
Case Report: A 63-year-old woman with a history of chronic kidney disease presented with a progressively enlarging mass in her right flank.

Background: In 2023 and 2024, a wide variety of new studies have been published in the field of soft tissue sarcomas, representing the enormous heterogeneity of sarcoma histotypes, anatomical location, treatment variability, and biological behavior.
Patients And Methods: This article summarizes the, in our view, seven most important publications in the field that will have an impact on the surgical practice and future treatment strategies of our patients.
Results: In the last year, we gained more insight in the genetic background of patients with sarcoma from a large Australian study, which will have an impact on future counseling and screening of our patients.
