Small Hard Lumps Near the Anus: Causes and Concerns

Small hard lump in the anus?

Hello Doctor, I recently discovered a small hard lump under the skin of my anus, located approximately between the internal and external anal sphincters.
It feels about 0.2 to 0.3 centimeters, is movable, and does not hurt.
A year ago, I had a similar issue in the same location, but that time it was painful; this time it is not painful, and it eventually disappeared.
What could this be?
Additional symptoms: I have mild hemorrhoids, no constipation, and I often feel a tearing sensation when my stool is a bit hard.
Thank you, Doctor.

More Info

The presence of small hard lumps near the anus can be concerning, and it’s important to understand the potential causes and implications. Based on your description, the lump you’ve noticed is approximately 0.2 to 0.3 cm, movable, and painless, which is a positive sign. However, given that you have a history of a similar lump that was painful and has since resolved, it’s essential to consider a few possibilities.

One common cause of small lumps in the anal area is the presence of anal warts, which are caused by the human papillomavirus (HPV). These can appear as small, hard lumps and may be painless. Another possibility is the formation of a small anal abscess or a fistula, which can occur due to infection or blockage of the anal glands. However, these typically present with pain and swelling, which you are not experiencing this time.

Given that you also mentioned having mild hemorrhoids, it’s possible that the lump could be related to this condition. Hemorrhoids can sometimes form small lumps or tags of tissue, especially after straining during bowel movements. These can be painless and may fluctuate in size.
Another potential cause could be a skin tag, which is a benign growth of skin that can occur around the anal area. Skin tags are usually painless and movable, similar to what you’ve described. They often arise after episodes of irritation or friction, which could be related to your experience of having rougher stools that cause skin irritation.

While the lump you describe does not seem to be causing any immediate issues, it’s crucial to monitor it for any changes in size, shape, or symptoms. If it becomes painful, changes in appearance, or if you notice any other concerning symptoms such as bleeding, it would be advisable to seek medical evaluation.

In terms of management, maintaining a healthy diet rich in fiber can help prevent constipation and reduce straining during bowel movements, which may alleviate some of the pressure on the anal area and prevent further irritation or the formation of new lumps. Staying hydrated and considering the use of over-the-counter stool softeners may also be beneficial.

Given your history of a similar lump and the presence of hemorrhoids, it would be wise to consult a healthcare professional for a thorough examination. They may perform a physical examination and possibly recommend further imaging or tests if necessary to rule out any serious conditions.
In summary, while the lump you’ve described could be benign, such as a skin tag or related to hemorrhoids, it’s essential to keep an eye on it and consult with a healthcare provider for a definitive diagnosis and peace of mind. Regular check-ups and being proactive about any changes in your body are key to maintaining good health.
