An anal fissure is a small tear in the thin, moist tissue mucosa that lines the anus. An anal fissure may occur when you pass hard or large stools during a bowel movement. Anal fissures typically cause pain and bleeding with bowel movements. You also may experience spasms in the ring of muscle at the end of your anus anal sphincter. Anal fissures are very common in young infants but can affect people of any age. Most anal fissures get better with simple treatments, such as increased fiber intake or sitz baths.

The anatomy of the anus and rectum dictates the clinical evaluation and treatment of patients with anorectal disorders Figure 31—1. From external to internal, the surface anatomy of the anorectum is comprised of gluteal skin, anoderm, the anal transitional zone, and proximally the rectal mucosa. The gluteal skin includes hair, sebaceous glands, and sweat glands. This area, particularly cm of anal margin skin circumferentially around the anus, can commonly become infected with the human papilloma virus resulting in anal condyloma. Anal condyloma can also affect more proximal tissue in the anoderm and lower rectal mucosa.
Your doctor will likely ask about your medical history and perform a physical exam, including a gentle inspection of the anal region. Often the tear is visible. Usually this exam is all that's needed to diagnose an anal fissure. An acute anal fissure looks like a fresh tear, somewhat like a paper cut.
