Anus hard white bump

Skip to content. Most lumps and swellings under the skin are harmless and can be left alone. However, see your GP if you develop a new lump or swelling so that the cause can be identified. You should see your GP if you develop any growth or swelling on your body. They can examine it and confirm what it is and what's causing it.

Finding a lump on any part of your body can be alarming, but try not worry. If you've found a small and often dark or black coloured lump on the outside of your anus that looks a bit like external piles , it is most likely a perianal haematoma. A perianal haematoma can be distinctly uncomfortable, and may leave you feeling worried or embarrassed, as well as in pain. A perianal hematoma is a blood blister that collects in the tissue surrounding the anus, similar to when you trap or hit your thumb with a hammer. It is usually caused by a ruptured or bleeding vein that occurs when the bowels are opened, and it only occurs on the outside of the anus, as opposed to being an internal issue.

Anal warts are small warts that can occur inside and around the anus. The condition is also called condyloma acuminata. Anal warts are a form of genital warts. However, they can become irritating if they grow large enough, and might itch or bleed. If no symptoms occur, people with anal warts may not even know they have them.

The anus is an opening in the lower part of the digestive tract. When stool fills the rectum, the sphincter muscle relaxes, letting stool pass through the anus and out of the body. The external anal sphincter closes off the anus when stool has passed. Lumps that form around the anus — for a variety of reasons — can cause it to feel hard. There may also be swelling, pain , and discharge.
