Anal skin tags are extra pieces of skin around the anus. They may form for several reasons but are often a result of having piles or an anal fissure. Although in themselves they are totally harmless, may people find them uncomfortable, unsightly and can make personal hygiene difficult. Skin tags can be easily removed under anaesthetic although the procedure is often painful afterwards. It is very important to find the exact cause of the skin tags to stop them coming back and therefore they should always be assessed by a specialist.
