a Hard, Painless Lump Near the Anus: What Could It Be? - Surgery

Share to:

While cleaning the anus, I felt a hard, round mass that is not painful and does not cause any sensation?


Hello, doctor.
When I was 17, I had my first colonoscopy, and the doctor told me I had hemorrhoids.
In May of this year, just two months ago, I had a second check-up, and my colon was fine, but I was informed that I have external hemorrhoids.
There were no other issues, and I didn't pay much attention to it since I didn't feel anything.
A few days ago, after using the restroom and cleaning my anal area, I felt a hard, round lump towards the direction of my genitals.
It's not deep or shallow; I have to apply some pressure with my finger to feel it, and it's located right at the anal closure.
I've been checking it daily to see what it is, and I'm a bit worried that it might be something serious.
It doesn't have any sensation, doesn't hurt, and it's just a hard, round lump.
When I press or move it, it feels like it's fixed in place and doesn't move with the skin.
I would like to ask the doctor what this is more likely to be.

Based on your description, it seems more like a thrombosed external hemorrhoid; however, a formal diagnosis should be made by a physician to confirm.
If the lump gradually diminishes and there is no redness, swelling, heat, or pain, you can continue to monitor it.
Otherwise, you should seek medical attention promptly to avoid delaying treatment.

More Info


When it comes to understanding a hard, painless lump near the anus, there are several potential explanations, especially considering your history of hemorrhoids. It’s important to approach this situation with a clear understanding of the possible causes, as well as the appropriate steps to take for evaluation and management.


Possible Causes
1. External Hemorrhoids: Given your previous diagnosis of hemorrhoids, it’s possible that what you are feeling is an external hemorrhoid. These are swollen veins that can form around the anus and may feel like a hard lump. They are usually painless unless they become thrombosed (clotted), which can cause significant pain.

2. Anal Skin Tags: After the resolution of hemorrhoids, skin tags can sometimes form. These are benign and typically painless, appearing as small, soft lumps near the anal area. They can feel firm and may be movable, but they do not usually cause discomfort.

3. Fistula or Abscess: An anal fistula is a small tunnel that can develop between the end of the bowel and the skin near the anus, often following an abscess. While these can sometimes be painful, they may also present as a firm lump without pain, especially if there is no active infection.

4. Lymphadenopathy: Enlarged lymph nodes in the groin or pelvic area can sometimes present as lumps near the anus. These are usually associated with infections or other systemic conditions.

5. Other Benign Growths: Other benign conditions, such as warts or fibromas, could also present as a hard lump. These growths are typically painless and can vary in size and shape.

6. Malignant Conditions: While less common, it is essential to consider the possibility of anal cancer or other malignancies, especially if there are changes in bowel habits, bleeding, or other systemic symptoms. However, the absence of pain and the nature of the lump make this less likely.


Next Steps
1. Self-Examination: While it’s understandable to want to monitor the lump, excessive manipulation can lead to irritation or infection. It’s best to limit this to occasional checks.

2. Consultation with a Healthcare Provider: It is crucial to schedule an appointment with a healthcare provider, preferably a gastroenterologist or a colorectal surgeon. They can perform a thorough examination, which may include a digital rectal exam or an anoscopy, to visualize the area better.

3. Diagnostic Imaging: If deemed necessary, your doctor may recommend imaging studies, such as an ultrasound or MRI, to assess the lump further.

4. Biopsy: If there is any concern about the nature of the lump, a biopsy may be performed to rule out malignancy.


Conclusion
While the lump you are describing is likely benign, given your history of hemorrhoids and the characteristics of the lump, it is essential to seek professional medical advice. Early evaluation can provide peace of mind and ensure that any necessary treatment is initiated promptly. Remember, it’s always better to err on the side of caution when it comes to changes in your body, especially in sensitive areas like the anal region.
