What Are Anal Skin Tags? Causes, Symptoms and Treatment Options

What is an anal or perianal skin tag?

A skin tag is a small growth or fold of skin. Healthdirect notes that skin tags can occur in body folds, including around the anus. A perianal skin tag is on the skin surrounding the anal opening rather than inside the rectum.

Tags vary in size, shape and texture. Some are soft and narrow-based while others are broader folds. These differences mean that written descriptions or photographs are not a reliable substitute for examination when the diagnosis is uncertain.

What can contribute to anal skin tags?

There is no single cause. Skin tags generally develop more often where skin rubs or is repeatedly irritated. In the anal area, a fold may be noticed after previous swelling, irritation, haemorrhoids or an anal fissure. Constipation, repeated straining, diarrhoea and frequent wiping can also irritate the area, although the presence of a tag does not prove any particular cause.

A skin tag does not automatically mean poor hygiene, a sexually transmitted infection or bowel disease.

What symptoms can they cause?

Many anal skin tags cause no symptoms. When symptoms occur, they may include:

• a small fold or lump felt during washing or wiping;
• local irritation or rubbing;
• difficulty cleaning comfortably after a bowel movement;
• intermittent tenderness if the area becomes inflamed;
• a sensation of extra skin around the anal opening.

Bleeding should not automatically be attributed to a skin tag. Rectal or anal bleeding has several possible causes and should be assessed, particularly if it is recurrent, unexplained or associated with pain, a change in bowel habit, weight loss or another concerning symptom.

Why can anal skin tags be confused with other conditions?

Haemorrhoids can cause lumps, swelling, discomfort and bleeding. Anal fissures can cause significant pain and bleeding and may be associated with a small external fold. Warts, inflammatory skin conditions, cysts and other lesions can also occur around the anus.

Less common but important conditions may also cause a persistent or changing anal lesion. Healthdirect advises medical review for a new lump, bleeding or other changes around the anus.

Key point: an anal skin tag is a description of a skin fold, not a diagnosis that should be assumed for every anal lump.

When is medical assessment recommended?

Assessment is appropriate if a lump is new, changing, painful, bleeding, difficult to identify or affecting hygiene or daily comfort. It is also appropriate before considering removal.

A clinician may ask about the duration of the symptom, bowel habit, previous haemorrhoids or fissures, constipation, inflammatory bowel disease, medicines that affect bleeding and previous anorectal procedures. An in-person examination may be needed even if a telehealth consultation is useful as a first discussion.

Depending on the finding, the clinician may recommend reassurance, conservative care, removal, investigation or referral to a colorectal surgeon, gastroenterologist, dermatologist or another appropriate practitioner.

What happens during an anal skin tag consultation?

The first goal is to establish what the lesion is. The practitioner reviews symptoms, relevant medical history and whether an in-person examination is required. If the finding is consistent with a benign skin tag, the discussion can then move to whether any treatment is necessary or optional.

A consultation can also cover hygiene concerns, recurrent irritation, expectations, wound healing and whether specialist referral would be more appropriate.

When may removal be considered?

Removal may be discussed when a confirmed skin tag is repeatedly irritated, interferes with cleaning, causes discomfort or when the patient wishes to consider removal after understanding the limitations and risks. A stable, asymptomatic tag does not need to be removed simply because it is present.

The exact technique, anaesthetic approach and aftercare depend on the lesion, location, clinician and individual health factors and must be confirmed by the treating clinician.

What risks and limitations should be discussed?

Procedures involving perianal skin may involve pain, bleeding, infection, swelling, scarring, delayed healing or recurrence. Constipation, diarrhoea, friction and individual healing can affect recovery. The final appearance and healing time cannot be guaranteed.

If the diagnosis is uncertain or symptoms suggest another anorectal condition, referral may be more appropriate than removal.

How can bowel habits affect the area?

Constipation, hard stools and repeated straining can contribute to haemorrhoids and fissures and can increase local irritation. Frequent loose stools can also irritate the perianal skin. If a person is considering removal, addressing an ongoing bowel problem may be important because the wound sits in an area exposed to repeated movement and bowel motions.

This does not mean a skin tag is caused by poor bowel habits. It means that bowel health may affect symptoms and recovery, and persistent constipation, diarrhoea or a change in bowel habit deserves its own assessment.

What should you avoid doing at home?

Do not cut, tie off, burn or use unapproved skin-tag products on a perianal lesion. The area has a rich blood supply and is prone to contamination. Home removal can cause bleeding, infection, burns, scarring or delayed diagnosis of a lesion that was not actually a skin tag.

If irritation is mild while waiting for assessment, gentle hygiene and avoiding excessive rubbing may help. Any treatment for pain, itching, constipation or haemorrhoids should be based on the diagnosed problem rather than assumed from appearance.

What questions are useful to ask at consultation?

Useful questions include:

• What do you think this lesion is and what features support that diagnosis?
• Is an in-person examination sufficient or is further investigation needed?
• Do I need treatment at all?
• What are the realistic benefits and limitations of removal in my case?
• What are the risks of pain, bleeding, infection, scarring, delayed healing or recurrence?
• How should bowel habits and wound care be managed during recovery?
• When should I contact the clinic or seek urgent care?
• Would referral to a colorectal surgeon or another specialist be more appropriate?

Why should cosmetic and medical concerns be separated?

Some people seek advice because they are worried about appearance, while others are primarily bothered by discomfort or hygiene. Both concerns can be discussed respectfully. However, appearance alone should not override the need to establish the diagnosis and explain the risks of creating a wound in the perianal area.

A clinician should also avoid implying that a normal or benign skin fold is unhygienic, abnormal or socially unacceptable. The decision to proceed should be voluntary and based on informed preference after reasonable alternatives, including no treatment, have been discussed.
