Pruritus ani
SpecialtyDermatology 

Pruritus ani is the irritation of the skin at the exit of the rectum, known as the anus, causing the desire to scratch.[1] The intensity of anal itching increases from moisture,[2] pressure, and rubbing caused by clothing and sitting. At worst, anal itching causes intolerable discomfort that often is accompanied by burning and soreness. It is estimated that up to 5% of the population of the United States experiences this type of discomfort daily.
