We experienced two cases of renal primary synovial sarcoma. Case 1: A 29-year-old man underwent laparoscopic radical nephrectomy and was originally diagnosed with renal cell carcinoma. Case 2: A 25-year-old man was treated by open radical nephrectomy since radiographical findings indicated tumor invasion to the ureter causing hydronephrosis. Both cases were pathologically diagnosed as renal synovial sarcomas, and were followed using computed tomography. Recurrence was observed within a year in both cases.

Locally advanced renal cell carcinoma (RCC) presents significant therapeutic challenges, particularly in resource-limited settings with restricted access to new therapies. This report describes a new exploratory multimodal therapeutic approach for a patient with locally advanced clear cell RCC (ccRCC) with adrenal and lymph node metastases. A 45-year-old woman presented with an incidentally discovered 9-cm mass in the left kidney, which was later diagnosed as grade-2 ccRCC with adrenal and lymph node involvement.

Background: Peritoneal recurrence (PREC) following nephrectomy for localized renal cancer (RCC) is rare. Our objective was to report a multicenter analysis of PREC to analyze incidence, treatment, survival and risk factors.
Methods: Between 1987 and 2023, patients with PREC following radical or partial nephrectomy (PN) for localized RCC across ten European institutions (UroCCR, NKI, IRCCS, Foch and Gustave Roussy centers) were included.

The evaluation and management of renal masses, predominantly of the clear cell renal cell carcinoma subtype, have been evolving over the past several years and demanding greater attention from nephrologists. Oncologic survival of localized tumors approaches 100%, where survival is more closely tied to underlying comorbidities including chronic kidney disease (CKD). Early diagnosis and thus increasing prevalence related to incidental discovery of renal masses allows greater emphasis on nephron-sparing procedures and for residual kidney function preservation.

We present the case of a 67-year-old female who developed simultaneous metastases to the ampulla of Vater and the breast. Her medical history is significant for a radical nephrectomy performed twenty-one years prior for renal cell carcinoma (RCC). The patient was referred for evaluation due to the development of progressive jaundice, fatigue, and weight loss.

Introduction: Immunoglobulin G4-related disease is a systemic fibroinflammatory disorder that affects the kidney, presenting as an immunoglobulin G4-related inflammatory pseudotumor. These renal inflammatory pseudotumors are usually solid, and cystic presentations have not been previously described.
Case Presentation: We report a 77-year-old man who presented with a Bosniak category III renal cystic mass and periaortic fibrous thickening.
