External urethral meatus cancer is a rare type of cancer that affects the opening of the urethra, known as the external urethral meatus. This guide provides detailed information about its definition, pathophysiology, types, causes, symptoms, diagnostic tests, treatments, prevention, and frequently asked questions.
External urethral meatus cancer refers to malignancies that develop in the external opening of the urethra. The urethral meatus is the gateway for urine to exit the body. While urethral cancer itself is uncommon, it can occur in both men and women, affecting the external meatus.
Pathophysiology
Structure
- Urethral Meatus: The external opening of the urethra located at the tip of the penis in males and between the clitoris and vaginal opening in females.
- Urethra: A tube that connects the bladder to the external meatus, allowing urine to pass out of the body.
Blood Supply
- Arterial Supply: Primarily supplied by branches from the internal pudendal artery, including the perineal artery.
- Venous Drainage: Blood drains through the deep dorsal vein of the penis in males and analogous veins in females.
Nerve Supply
- Autonomic Nerves: Control involuntary functions like bladder control.
- Somatic Nerves: Responsible for sensation in the meatus area.
Types of External Urethral Meatus Cancer
- Squamous Cell Carcinoma: Most common type, originating from the flat cells lining the meatus.
- Adenocarcinoma: Develops from glandular cells that produce mucus.
- Transitional Cell Carcinoma: Originates from the transitional epithelium.
- Basal Cell Carcinoma: Rare, starts in the basal cells of the skin.
- Melanoma: Extremely rare, arises from pigment-producing cells.
Causes
External urethral meatus cancer can result from various factors, including:
- Human Papillomavirus (HPV) Infection
