Pruritus ani is defined as an intense itching sensation affecting the perianal skin. The condition affects up to 5% of the population, and occurs four times more commonly in men than in women. Pruritus ani occurs in a primary form caused by overt but insufficient cleansing of the perianal skin, and in a secondary form caused by underlying pathology, often of proctological or dermatological/infectious origin. Causes and treatment are reviewed, and it is concluded that the condition, even in its chronic refractory form, has a favourable prognosis.
