Summary
A rare granular cell tumor (GCT) was found in a man
Area of Science:
- Urology
- Pathology
- Oncology
Background:
- Granular cell tumors (GCTs) are rare neoplasms of neural crest origin.
- While most commonly found in the soft tissues, GCTs can occur in various organs, including the urinary bladder.
- Bladder GCTs are exceptionally uncommon, with limited reported cases.
Purpose of the Study:
- To report a case of a granular cell tumor (GCT) of the urinary bladder.
- To review the existing literature on GCTs in the urinary bladder.
Main Methods:
- Case presentation of a 67-year-old Korean man with gross, painless hematuria.
- Diagnostic procedures included cystoscopy and transurethral resection.
- Histological examination and immunohistochemical staining confirmed the diagnosis.
Main Results:
- A 1 cm semispherical tumor was identified, covered by normal bladder mucosa.
- Histopathology and immunohistochemistry confirmed a granular cell tumor (GCT).
- The tumor showed no signs of malignancy, and the patient remained recurrence-free post-surgery.
Conclusions:
- Granular cell tumors (GCTs) of the urinary bladder are rare but benign entities.
- Transurethral resection is an effective treatment for bladder GCTs.
- These tumors have a favorable prognosis with no recurrence observed in this case.

01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...
01:28Urinary Tract Calculi I: Introduction
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...
01:26Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
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...
01:11Anatomy of the Genitourinary System I: Kidneys and Ureters
The upper urinary system comprises two kidneys and two ureters, which are crucial in filtering blood and forming urine.KidneysLocation and Structure:The kidneys are two bean-shaped organs positioned behind the peritoneum on either side of the spine.Kidneys are between the 12th thoracic (T12) and the 3rd lumbar (L3) vertebrae.The position of the liver causes the right kidney to sit slightly lower than the left.Protective Layers:Each kidney is enveloped in a tough, fibrous membrane called the...
