Anal Canal Masses

Anatomy of the Anal Canal

Structure:

The anal canal is about 3 to 5 cm long and connects the rectum to the outside of the body. It has two main parts:

• Upper part: Lined by simple columnar epithelium, similar to the rectum.
• Lower part: Lined by squamous epithelium, similar to skin.

Layers of the Anal Canal:

1. Mucosa: The inner lining that produces mucus to lubricate stool passage.
2. Submucosa: Contains blood vessels and nerves.
3. Muscle layers:
   • Internal anal sphincter: A smooth muscle that controls the involuntary release of stool.
   • External anal sphincter: A skeletal muscle that controls voluntary stool release.

Blood Supply:

• Superior rectal artery from the inferior mesenteric artery.
• Middle rectal artery from the internal iliac artery.
• Inferior rectal artery from the internal pudendal artery.

Nerve Supply:

• Somatic innervation: Controlled by the pudendal nerve for voluntary muscle control.
• Autonomic innervation: Sympathetic and parasympathetic fibers for involuntary muscle control.

Types of Anal Canal Masses

• Hemorrhoids: Swollen blood vessels in the anal canal.
• Anal polyps: Small growths in the lining of the anal canal.
• Anal fissures: Small tears in the lining of the anal canal.
• Anal cancer: Malignant? growths that develop from the lining of the anal canal.
• Perianal abscesses: Infected masses filled with pus.
• Anal warts (Condyloma acuminata): Caused by the human papillomavirus (HPV).

13. Endoanal ultrasound?: An internal ultrasound? specifically for the anal canal.
14. Stool DNA test: Detects genetic changes in stool that could indicate cancer.
15. Tumor markers: Blood tests that detect certain proteins produced by cancer cells.
