  https://www.uptodate.com/contents/approach-to-the-patient-with-anal-pruritus

  Itching of the anus or perianal skin is a common disorder usually arising from benign conditions. It may be transient or chronic and difficult to treat. This topic will review the etiology, diagnostic approach, and management of patients with anal pruritus. […] Anal pruritus is estimated to affect 1 to 5 percent of the general population. However, most of these patients probably do not come to medical attention. Anal pruritus is more common in the fourth to sixth decades of life and has a higher prevalence in males. […] Approximately 75 percent of cases of anal pruritus are secondary to inflammatory, infectious, systemic, neoplastic, and anorectal disorders that contribute to or underlie the development of pruritus.

• #2 Itchy Bottom (Pruritus Ani): Causes and Treatment

  https://patient.info/skin-conditions/itchy-bottom-pruritus-ani

  An itchy bottom (pruritus ani) is a persistent itch around the anus. There are many different causes, like haemorrhoids, skin conditions, or infections. Treatments depend on the cause, but include hygiene measures and creams or ointments to treat the itching. […] An itchy bottom (pruritus ani) is a common problem but the exact number of people who develop an itchy bottom is unknown. Some sources suggest around 1 to 5 out of every 100 people have an itchy bum. This is probably an underestimate, as many people don’t see a doctor about it. It seems to be about four times more common in men than in women. It most commonly affects people between the ages of 40-60. However, it can affect people of any age, including children. […] Various conditions may cause an itchy bottom. When the cause is another condition which has been identified, this is known as secondary pruritus ani. However, in many cases the cause is not clear. This is called 'idiopathic pruritus ani’ which means 'itchy anus of unknown cause’. Up to 90% of cases of pruritus ani may be idiopathic.

  Anal pruritus is a frequent disorder accounting for many proctological consultations, affecting mainly middle-aged males. It is believed that it implies a vicious circle of itching and scratching, increasing irritation and inflammation, and thus symptoms. The most frequent causes are irritant factors such as anal over-hygiene and some foods, faecal soiling due to incontinence, and proctological diseases such as haemorrhoids. […] Anal itching affects about 1 to 5% of the population, with a higher prevalence in men (4:1). It is more frequent in the adult population between 40 and 60 years old. It represents the second most common proctological complaint after haemorrhoids. […] About 100 possible causes have been identified. It can be classified into primary (idiopathic) or secondary. Idiopathic pruritus ani remains an exclusion diagnosis. Main secondary causes can be classified into local irritation, infections, proctological diseases, neoplastic lesions, dermatological and systemic diseases, and other aetiologies.

  Pruritis ani most commonly affects adults, affecting from 1% to 5% of people in the general population. Men are more commonly affected than women with a 4:1 ratio. The condition is most common in people age 40s to 60s. […] While this is a wide variety of potential causes, it is important to understand that in many cases the itching has no identifiable source. […] A careful medical history must be obtained from the patient focusing on the timing and duration of the pruritis ani as well as any accompanying symptoms. […] The goal of therapy is to restore clean, dry, and intact skin. Treatment can be challenging, as many cases have no clear identifiable cause. […] In order to control symptoms, a short course of a steroid ointment may be tried. A weak topical steroid such as 1% hydrocortisone cream used two to three times a day for a short period of time can be effective in relieving symptoms of pruritis.

[…] Most studies suggest an underlying cause in half to three quarters of people with pruritus ani. […] Looking at the medical literature published over the past century, approximately 100 conditions have been reported to be associated with pruritus ani. […] Any medical condition affecting the lower bowel, anus, and the surrounding skin can cause itchiness in the anal area. […] When no definite cause of pruritus ani can be found in a patient who has been fully investigated by colonoscopy, examination under anaesthesia of the anorectum, and biopsy of the skin, the condition is labelled as idiopathic.

• #12 Pruritus Ani: Causes and Treatment | Doctor

  https://patient.info/doctor/pruritus-ani

  Pruritus ani can be an important symptom secondary to specific disease processes. Inflammatory diseases of the skin, infections, infestations, premalignant and malignant neoplasms, and anorectal and systemic diseases may cause perianal itching. More often, there is no disease-specific aetiology and this is called idiopathic pruritus ani, which is responsible for 50-90% of cases, and affects 1-5% of the general population. Pruritus ani is four times more common in men than in women. It can occur at any time of life but is more common between 40-60 years of age. […] It is important to identify and eliminate any underlying causes, which may include unintentional consequences of the patient’s attempts to alleviate symptoms. Treatment otherwise depends on any underlying cause but, if no reversible cause is found, simple measures with diet modification and perianal hygiene should be tried before using any topical medications or procedures. […] Unless a cause is found it may become a chronic complaint. However, for most people the symptoms of pruritus ani will resolve with self-care measures and symptomatic treatment, but sometimes with periodic relapse.

  Anal pruritus is a frequent disorder accounting for many proctological consultations, affecting mainly middle-aged males. […] Anal itching affects about 1 to 5% of the population, with a higher prevalence in men (4:1). […] It represents the second most common proctological complaint after haemorrhoids. […] The treatment relies on the identification of a potential aetiology, and should be based on a step-up approach. […] Anal pruritus is a common source of proctological consultations, and the appropriate management depends on the identification of a potential secondary cause through rigorous history taking, physical examination and directed complementary investigations.

  Pruritis ani most commonly affects adults, affecting from 1% to 5% of people in the general population. Men are more commonly affected than women with a 4:1 ratio. The condition is most common in people age 40s to 60s. […] While this is a wide variety of potential causes, it is important to understand that in many cases the itching has no identifiable source. […] A careful medical history must be obtained from the patient focusing on the timing and duration of the pruritis ani as well as any accompanying symptoms. […] The goal of therapy is to restore clean, dry, and intact skin. Treatment can be challenging, as many cases have no clear identifiable cause. […] In order to control symptoms, a short course of a steroid ointment may be tried. A weak topical steroid such as 1% hydrocortisone cream used two to three times a day for a short period of time can be effective in relieving symptoms of pruritis.

  Pruritus ani is a common condition that causes irritating and uncomfortable itching around the anus (opening of the rectum), followed by an urge to scratch. Affecting about five percent of the population, pruritus ani is more commonly diagnosed in patients between 40 and 60 years old, and can result from skin conditions, infections, disease, and hygiene habits. […] Patients generally experience bothersome symptoms after a bowel movement or during the night. […] There are a number of possible causes for anal itching, including: […] During your visit, we can review your medical history to determine contributing factors. […] Because anal itching is a symptom, your colorectal specialist can perform a rectal examination to identify if you have hemorrhoids, fissures, eczema, or another abnormality causing your discomfort. […] The type of treatment we recommend will depend on the root of your issue. In cases where the cause of your condition is easily identifiable, your specialist can recommend a medication to treat the issue.
