Summary
This summary is machine-generated.Pediatric renal cell carcinoma (RCC) is rare. This case study details a 4-year-old boy with translocation-associated RCC, successfully treated with surgery and showing no recurrence after 36 months.
Area Of Science
- Pediatric Oncology
- Urologic Pathology
- Medical Imaging
Background
- Renal cell carcinoma (RCC) is a rare malignancy in children, distinct from Wilms tumor.
- Accurate diagnosis is vital due to differing treatment protocols and prognoses.
- Translocation-associated RCC is the most common pediatric subtype, primarily managed with surgery.
Purpose Of The Study
- To report a case of translocation-associated RCC in a pediatric patient.
- To highlight diagnostic and management strategies for pediatric RCC.
- To emphasize the importance of long-term follow-up for late recurrences.
Main Methods
- A 4-year-old boy presented with fever and abdominal distension.
- Diagnostic imaging included CT and FDG-PET scans, revealing a complex cystic renal mass.
- Treatment involved radical nephrectomy with lymph node dissection, followed by histopathological and immunohistochemical analysis.
Main Results
- Imaging indicated a Bosniak category IV cystic mass with enlarged lymph nodes.
- Histopathology confirmed translocation-associated RCC with specific cellular and nuclear features.
- Immunohistochemistry showed positivity for TEF3, keratin, and vimentin, with a KI-67 index of 10-20%.
- The patient achieved pT2aN0 stage and experienced an uneventful recovery.
Conclusions
- Surgical resection is the primary treatment for pediatric translocation-associated RCC.
- Early diagnosis and appropriate management are crucial for favorable outcomes.
- The patient remained recurrence-free at 36 months post-surgery, underscoring the need for sustained follow-up.

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
