Primary malignant melanoma of the urinary bladder is a rare diagnosis. This case highlights a rare instance in an elderly patient with advanced disease and no prior skin melanoma history.
Area of Science:
- Oncology
- Uropathology
Background:
- Primary malignant melanoma of the urinary bladder is exceedingly rare, with limited documented cases.
- Melanoma typically originates in the skin, making bladder origin highly unusual.
Observation:
- An 87-year-old female patient presented with advanced urinary bladder neoplasm.
- No history of cutaneous melanoma or concurrent skin lesions was noted.
Findings:
- Histopathologic examination confirmed melanoma of the urinary bladder.
- The patient underwent tumor resection but succumbed to widespread metastatic disease.
Implications:
- This case underscores the importance of considering rare diagnoses in urologic oncology.
- Further research into the etiology and management of primary bladder melanoma is warranted.

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...
01:13Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
