External Anal Sphincter Cysts 

Anatomy of the External Anal Sphincter

Understanding the external anal sphincter is essential to grasp how cysts form and affect this area.

Structure

• Location: Surrounds the anal canal, extending from the pubis to the coccyx (tailbone).
• Composition: Made of skeletal muscle, meaning it’s under voluntary control.
• Function: Maintains continence by contracting to close the anus and relaxes during bowel movements.

Blood Supply

• Arteries: Primarily supplied by the superior and inferior rectal arteries.
• Veins: Drained by the superior and inferior rectal veins, which are part of the hemorrhoidal plexus.

Nerve Supply

• Innervation: Supplied by the inferior rectal nerves, branches of the pudendal nerve.
• Function: Controls muscle contractions and relaxations for continence.

Types of External Anal Sphincter Cysts

External anal sphincter cysts can vary based on their origin and characteristics. Here are the primary types:

1. Anal Gland Cysts:
   • Formed from blocked anal glands.
   • Commonly develop into abscesses or fistulas if untreated.
2. Pilonidal Cysts:
   • Occur near the coccyx.
   • Often contain hair and skin debris.
3. Inclusion Cysts:
   • Result from skin trauma or surgery.
   • Trapped skin cells form a cyst.
4. Sebaceous Cysts:
   • Originates from sebaceous glands.
   • Filled with oily substances like sebum.
5. Epidermoid Cysts:
   • Formed from epidermal cells.
   • Contain keratin and dead skin cells.
6. Steatocystoma:
   • Develops from sebaceous glands.
   • Typically larger and contain sebum.
7. Abscess?-Related Cysts:
   • Result from untreated infections.
   • Filled with pus and inflammatory materials.
8. Tailgut Cysts:
