a Bump in the Anal Fold: What You Need to Know

There is a protrusion in the anal fold?

Hello, doctor! While showering, I noticed a bump that feels like a pimple in the folds of my anus.
It doesn't hurt, and when I looked in the mirror, I saw a white bump about 0.2 centimeters in size.
It feels like a pimple or a small raised mole and has been there for about a month.
Last week, I visited a gynecologist due to a vaginal infection and asked the doctor to check it out.
The doctor said it wasn't very clear and suggested monitoring it further.
I have no sexual history, so I would like to ask what this could be!

Perianal masses are mostly external hemorrhoids, anal fistula openings, or anal fissure polyps.
Without a physical examination, a definitive answer cannot be provided.
However, if there is no pain and the mass has not increased in size, it can be monitored further.

More Info

When you discover a bump in the anal fold, it can understandably cause concern. Based on your description, it sounds like you have a small, painless, white bump that resembles a pimple or a small mole. Given that it has been present for about a month and has not caused any pain or discomfort, there are several potential explanations for this finding.

One common cause of such bumps in the anal area is the presence of a sebaceous cyst. These cysts occur when the sebaceous glands, which produce oil to lubricate the skin, become blocked. They can appear as small, painless lumps and are generally harmless. Another possibility is a skin tag, which is a benign growth of skin that can occur in various areas of the body, including the anal region. Skin tags are usually soft and can vary in size and color.

Another potential cause could be hemorrhoids, which are swollen blood vessels in the rectal area. While hemorrhoids can be painful, they can also be painless and may present as small lumps. However, they typically do not appear as white bumps.

In some cases, a bump in the anal area could be related to warts, which are caused by the human papillomavirus (HPV). These can appear as small, flesh-colored or white bumps and may require treatment if they are bothersome or if there is any concern about their nature.

Given that you have no sexual history and the bump has been present for a month without any changes, it is less likely to be a sexually transmitted infection. However, it is still important to monitor the bump for any changes in size, color, or symptoms such as pain or bleeding.

Since you have already consulted with a gynecologist, it is wise to follow their advice to observe the bump. If it does not resolve or if you notice any changes, it would be prudent to seek further evaluation from a healthcare provider, such as a dermatologist or a proctologist, who specializes in conditions of the skin and anal area.

In summary, while the bump you are experiencing is likely benign, it is essential to keep an eye on it and consult with a healthcare professional if you have any concerns or if it changes in any way. Regular check-ups and open communication with your healthcare provider are key to ensuring your health and peace of mind.
