Anal abscess - An anal abscess is a swollen, painful collection of pus near the anus. Most anal abscesses are not related to other health problems and arise spontaneously, for reasons that are unclear. They originate in a tiny anal gland, which enlarages to create a site of infection under the skin. In the United States, more than half of all anal abscesses occur in young adults between the ages of 20 and 40, and men are affected more often than women. Most anal abscesses are located near the opening of the anus but rarely can occur deeper or higher in the anal canal, closer to the lower colon or pelvic organs.
