Summary
Primary renal synovial sarcoma is a rare kidney tumor. This report details a case of the monophasic variant, which is more common and has a better prognosis.
Area of Science:
- Oncology
- Pathology
Background:
- Primary renal synovial sarcoma (SS) is an exceptionally rare kidney neoplasm.
- First described by Faria in 1999, only 21 cases have been documented globally.
- Renal SS presents in monophasic or biphasic histological patterns.
Observation:
- This report focuses on a 61-year-old female patient.
- The patient presented with a monophasic variant of primary renal synovial sarcoma.
- Monophasic renal SS is more frequently encountered than the biphasic type.
Findings:
- The monophasic variant of primary renal synovial sarcoma is associated with a more favorable prognosis compared to the biphasic variant.
- This case contributes to the limited literature on renal SS, specifically the monophasic subtype.
- The study highlights the occurrence of this rare tumor in a 61-year-old woman.
Implications:
- Understanding the prognostic differences between monophasic and biphasic renal SS is crucial for patient management.
- Further research into rare renal tumors like synovial sarcoma is warranted.
- This case report adds valuable data to the understanding of primary renal synovial sarcoma epidemiology and presentation.

01:21External Anatomy of the Kidney
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...

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
01:12Internal Anatomy of the Kidney
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.
Renal Cortex
The outermost region of the kidney is the...

01:26Kidney Transplant II: Surgical Procedure
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
