Summary
Renal primitive neuroectodermal tumor (PNET) is a rare kidney cancer. This case highlights the diagnostic challenges and importance of immunohistochemistry for accurate PNET diagnosis and patient management.
Area of Science:
- Oncology
- Pathology
Background:
- Renal primitive neuroectodermal tumor (PNET) is an exceptionally rare kidney malignancy.
- Accurate differentiation from other small round cell tumors is crucial for effective patient management.
Observation:
- A 45-year-old male presented with abdominal pain, hematuria, and a palpable abdominal mass.
- Imaging revealed a cystic-solid right renal mass suspicious for malignancy.
Findings:
- Histopathology diagnosed a malignant small round blue cell tumor.
- Immunohistochemistry confirmed CD99 positivity, establishing the diagnosis of primary renal PNET.
Implications:
- This case underscores the rarity of renal PNET and the diagnostic complexities involved.
- Highlighting the role of immunohistochemistry in confirming PNET diagnosis is vital for guiding treatment strategies.

75.5K
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

01:28Kidney Transplant I: Introduction
498
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.

200.7K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...
