Summary
A rare benign bladder tumor, chondroma, was diagnosed in a 67-year-old woman presenting with microscopic hematuria. This fifth documented case highlights chondroma
Area of Science:
- Uropathology
- Oncology
- Histology
Background:
- Chondroma is a benign mesenchymal tumor characterized by cartilage formation.
- It rarely occurs in soft tissues and has been documented in the bladder only four times previously.
- Bladder tumors can present with various symptoms, including hematuria.
Observation:
- A 67-year-old woman presented with microscopic hematuria.
- Endoscopic examination revealed a submucosal nodular lesion on the anterior bladder wall.
- The lesion was surgically resected for further analysis.
Findings:
- Histological examination confirmed the presence of cartilage and fibroconnective tissue, partly hyalinized.
- Immunohistochemical staining showed positive results for vimentin and S-100.
- These findings support the diagnosis of bladder chondroma.
Implications:
- This case adds to the limited literature on bladder chondromas.
- Accurate diagnosis is crucial for appropriate patient management.
- Further research may elucidate the pathogenesis and optimal treatment strategies for this rare tumor.

3.7K
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...

1.8K
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...

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...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
