Summary
Renal primitive neuroectodermal tumors (PNET) are rare and aggressive kidney cancers, often diagnosed late due to nonspecific symptoms. Early diagnosis via histopathology and immunohistochemistry is crucial for managing this challenging neoplasm.
Area of Science:
- Oncology
- Pathology
Background:
- Renal sarcomas are exceedingly rare, comprising <1% of all kidney malignancies.
- Primitive neuroectodermal tumor (PNET) of the kidney is an extremely rare and aggressive neoplasm, with limited reported cases, primarily affecting young adults.
- Pediatric cases of renal PNET are exceptionally uncommon.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:26Nursing Assessment of the Genitourinary System II: Inspection and Palpation
The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...
