Anal verge cancer, also known as anal cancer, is a rare type of cancer that occurs at the end of the digestive tract, in the anal canal or on the skin surrounding it. Understanding its anatomy, causes, symptoms, and treatments is crucial for awareness and prevention.
Anatomy of the Anal Verge
Structure: The anal verge consists of several components:
- Anal Canal: The short tube leading from the rectum to the outside of the body, about 2-4 cm long.
- Anal Sphincters: Muscles that control the passage of stool.
- Skin: The outer layer surrounding the anal canal.
Blood Supply:
- Blood is supplied by the inferior mesenteric artery and the internal pudendal artery.
Nerve Supply:
- The anal area is innervated by the inferior rectal nerve and the pelvic plexus, allowing for sensation and control.
Types of Anal Verge Cancer
- Squamous Cell Carcinoma: The most common type, originating in the flat cells lining the anal canal.
- Adenocarcinoma: Arises from glandular cells, less common than squamous cell carcinoma.
- Melanoma: A rare form that develops from pigment-producing cells.
- Basal Cell Carcinoma: Rarely occurs in the anal region, typically associated with the skin.
