An external urethral orifice tumor is a rare growth or lump that forms at the opening of the urethra, which is the tube that allows urine to leave the body. The urethra has two ends: the internal end, which connects to the bladder, and the external end, which is the opening through which urine is excreted. This tumor can either be benign (non-cancerous) or malignant (cancerous), and it may cause various symptoms depending on its size and location.
Pathophysiology
Structure and Blood Supply
The urethra is a tube-like structure that runs from the bladder to the external opening. The external urethral orifice, or the meatus, is located at the tip of the penis in men and just above the vaginal opening in women. The blood supply to the urethra comes from small branches of the internal iliac artery.
- Nerve Supply: The urethra is innervated by the autonomic nervous system (sympathetic and parasympathetic nerves), and sensory nerves from the pudendal nerve.
Tumor Formation
The tumor can arise from the tissues of the urethra, such as the epithelium or glandular tissues. In rare cases, tumors can grow outward from the skin or other surrounding tissues.
Types of External Urethral Orifice Tumors
- Benign Tumors:
- Papillomas: Non-cancerous growths that may appear as small, wart-like bumps.
- Fibromas: Benign tumors made of fibrous tissue.
- Hemangiomas: Tumors consisting of blood vessels.
- Leiomyomas: Tumors made from smooth muscle tissue.
- Malignant Tumors:
- Squamous Cell Carcinoma (SCC): A type of skin cancer that can develop in the urethra.
- Adenocarcinoma: Cancer that originates from glandular tissue within the urethra.
- Transitional Cell Carcinoma (TCC): A cancer originating from the transitional epithelium lining the urethra.
