Anal canal masses refer to any abnormal growth or swelling in the anal canal. The anal canal is the final part of the digestive tract through which stool leaves the body. These masses may be benign (non-cancerous) or malignant (cancerous). Early diagnosis and proper treatment are crucial for preventing complications.
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:
- Mucosa: The inner lining that produces mucus to lubricate stool passage.
- Submucosa: Contains blood vessels and nerves.
- 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).

Diagnostic Tests for Anal Canal Masses
- Physical examination: The doctor checks for external lumps or masses.
- Digital rectal exam (DRE): A finger examination to feel for internal masses.
- Anoscopy: A small tube with a light is inserted into the anus to examine the anal canal.
- Proctoscopy: Similar to anoscopy but allows for a deeper view into the rectum.
- Colonoscopy: A scope examines the entire colon and rectum for masses.
- Flexible sigmoidoscopy: A scope checks the rectum and lower colon.
- Biopsy: Tissue from the mass is taken and examined under a microscope.
- Fecal occult blood test (FOBT): Checks for hidden blood in the stool.
- CT scan: Imaging to detect abnormal growths.
- MRI: Provides detailed images of the soft tissues around the anal canal.
- Ultrasound: Sound waves create images of the anal canal.
- PET scan: A scan to detect cancer spread.
- Endoanal ultrasound: An internal ultrasound specifically for the anal canal.
- Stool DNA test: Detects genetic changes in stool that could indicate cancer.
- Tumor markers: Blood tests that detect certain proteins produced by cancer cells.
- Barium enema: An X-ray exam with a contrast dye to view the lower digestive tract.
- Virtual colonoscopy: A non-invasive CT scan-based procedure to detect abnormalities.
- HPV test: Detects human papillomavirus, a cause of anal cancer.
- Punch biopsy: A small piece of skin is removed for examination.
- Excisional biopsy: The entire mass is removed and tested for cancer.
Non-Pharmacological Treatments for Anal Canal Masses
- High-fiber diet: To prevent constipation and strain.
