An anal abscess is an infected cavity filled with pus found near the anus or rectum. Ninety percent of abscesses are the result of an acute infection in the internal glands of the anus. Occasionally, bacteria, fecal material or foreign matter can clog an anal gland and tunnel into the tissue around the anus or rectum, where it may then collect in a cavity called an abscess.

An anorectal abscess also referred to as an anal abscess, rectal abscess, perianal abscess, or perirectal abscess depending on its location is a pus-filled cavity that forms within the furrows of the anal canal called the anal sinuses. As your body tries to control the infection, white blood cells killed in the battle and other bodily fluids start to collect in the tissue, forming a pocket of pus. Abscesses can form near or within the anus or develop much higher up in the rectum itself.
Epidermal cysts are very common lesions. Here we present the unusual case of an epidermal cyst occurring between the anal sphincters, presenting as a lump in the perineum.
