Urethral crest cancer refers to malignant growths that develop in the urethral crest, a specific area within the male or female urethra. The urethral crest is a ridge of tissue lining the inside of the urethra, which is the tube that carries urine from the bladder out of the body. While urethral cancer is rare, understanding its development, symptoms, and treatment options is crucial for early detection and effective management.
Pathophysiology
Understanding how urethral crest cancer develops involves looking at the structure, blood supply, and nerve connections of the urethral crest.
Structure
- Urethral Crest: A central ridge inside the urethra that provides structural support.
- Epithelial Cells: Cells lining the urethral crest can become cancerous due to mutations.
Blood Supply
- Arterial Supply: The urethral crest receives blood from branches of the internal pudendal artery.
- Veins: Blood is drained via the internal pudendal veins, facilitating the spread of cancer cells.
Nerve Supply
- Sensory Nerves: Provide sensation to the urethra.
- Autonomic Nerves: Control involuntary functions like muscle contractions in the urethral walls.
Cancer Development
Cancer begins when normal cells in the urethral crest mutate and start to grow uncontrollably, forming tumors that can invade nearby tissues and spread to other parts of the body.
Types of Urethral Crest Cancer
Urethral crest cancer can be categorized based on the type of cells involved and their location within the urethra.
- Transitional Cell Carcinoma: Originates from the cells lining the urethra and bladder.
- Squamous Cell Carcinoma: Develops from flat cells lining the urethra.
- Adenocarcinoma: Arises from glandular cells within the urethral crest.
- Sarcoma: Originates from connective tissues like muscles or fat.
- Melanoma: Develops from pigment-producing cells.
Causes and Risk Factors
While the exact cause of urethral crest cancer isn’t always clear, several factors can increase the risk:
- Age: Higher incidence in older adults.
- Gender: More common in men due to longer urethras.
- Chronic Infections: Recurrent urinary infections can increase risk.
