Summary
This study details a rare case of a 73-year-old woman with synchronous angiomyolipoma (AML) and two oncocytomas (OCs) in the same kidney. The findings highlight a potential increased association between AML and OC renal tumors.
Area of Science:
- Urology
- Nephrology
- Oncology
Background:
- Synchronous renal tumors are uncommon, with conventional renal cell carcinoma most frequently reported alongside angiomyolipoma (AML).
- Oncocytomas (OCs) are benign renal neoplasms, and their co-occurrence with AML is exceptionally rare.
Observation:
- A 73-year-old woman presented with a staghorn calculus and was incidentally found to have a suprarenal mass and a renal nodule.
- Radiographic findings led to a radical nephrectomy, revealing a suprarenal angiomyolipoma (AML) and two renal oncocytomas (OCs) within the same kidney.
Findings:
- The case documents the simultaneous presence of angiomyolipoma (AML) and two oncocytomas (OCs) in a single kidney, a rare pathological finding.
- Analysis suggests a potentially higher-than-expected proportion of oncocytomas (OCs) among concurrent renal tumors associated with angiomyolipoma (AML).
Implications:
- This case contributes to the limited literature on the coexistence of angiomyolipoma (AML) and oncocytoma (OC).
- Further research is warranted to investigate a possible pathogenetic link between AML and OC development.
- The findings may influence diagnostic and management strategies for patients with coexisting renal neoplasms.

01:20Renal Corpuscle
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

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...

01:18Blood and Nerve Supply to the Kidney
The kidneys are vital organs responsible for filtering and cleaning blood, removing waste products, and regulating electrolyte levels. To perform these essential functions, they require a constant and robust blood supply.
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of each...

01:24Renal Tubule and Collecting Duct
The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

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...

01:28Imaging Studies I: Kidney, Ureter, and Bladder Studies
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...
