Hard lump near the anus?


Hello, doctor.
I have a hard lump near my anus that has been present for over a year.
Before this lump appeared, I had an experience with an anal abscess that was treated with antibiotics.
About six months after the treatment, this lump developed.
When I consulted a doctor, he said it was hemorrhoids, but I feel it's a bit far from the anus, and I am worried it might be a recurrence of the abscess.
It doesn't hurt or itch (which feels completely different from the abscess I had), and there are no secretions, and its size hasn't changed.
Yesterday, it suddenly developed a small hole, and when I pressed it, a little blood came out, and the lump became very small.
I am very scared it might be a fistula or abscess, but there is no pus or discharge.
Should I continue to observe it since the lump has already decreased?

If the affected area previously had an anal abscess that was treated and then recurs in the same location, it may indicate the presence of a fistula, which connects the affected area to the anal glands, making it prone to recurrent inflammation.
If symptoms such as redness, swelling, heat, and pain are not pronounced, observation may continue; however, if a hard lump persists and its size increases, it is important to seek medical evaluation promptly.
Once a fistula forms, it is difficult to heal on its own, and surgical treatment should be considered.

More Info


Understanding hard lumps near the anus can be concerning, especially given your history of anal abscess. Based on your description, it seems you have a hard lump that has persisted for over a year, which was initially thought to be a hemorrhoid by your doctor. However, your concern about it being a recurrent abscess or a fistula is valid, especially since it recently ruptured and bled slightly.

First, let's clarify some terms and conditions that might relate to your situation:
1. Hemorrhoids: These are swollen veins in the lower rectum and anus that can cause discomfort, bleeding, and lumps. They can be internal or external. Given that your lump is located away from the anus, it may not be a typical hemorrhoid, but external hemorrhoids can sometimes present as lumps that are not directly at the anal opening.

2. Anal Abscess: This is a collection of pus that can occur due to infection in the anal glands. If you had an abscess previously, it is possible for a fistula (an abnormal connection between the anal canal and the skin) to develop afterward. Fistulas can sometimes present as lumps near the anus.

3. Fistula-in-Ano: This is a condition where a tunnel forms between the anal canal and the skin near the anus, often as a result of a previous abscess. Symptoms can include discharge, pain, and swelling, but some fistulas can be asymptomatic.

4. Other Conditions: Other potential causes of lumps in that area include skin tags, warts, or even cysts. These can be painless and may not require treatment unless they become bothersome.

Given that your lump has decreased in size after rupturing and does not exhibit signs of infection (such as pus or significant pain), it may be a good sign. However, the fact that it has been present for over a year warrants further evaluation.


Recommendations:
1. Observation: If the lump has significantly decreased in size and you are not experiencing pain, itching, or discharge, you may choose to observe it for a while longer. However, keep an eye on any changes in size, color, or if any new symptoms develop.

2. Follow-Up: It is crucial to follow up with a healthcare provider, preferably a colorectal specialist or a surgeon who specializes in anal and rectal conditions. They can perform a thorough examination and may recommend imaging studies (like an ultrasound or MRI) to assess for any underlying issues, such as a fistula or recurrent abscess.

3. Document Symptoms: Keep a record of any changes in the lump, such as size, shape, or any associated symptoms like pain or bleeding. This information will be helpful for your doctor during your next visit.

4. Avoid Self-Diagnosis: While it’s natural to worry about the possibility of a serious condition, self-diagnosing can lead to unnecessary anxiety. Trust your healthcare provider to guide you through the diagnostic process.

5. Seek Immediate Care if Needed: If you experience increased pain, fever, or any signs of infection (such as pus or increased swelling), seek medical attention promptly.

In conclusion, while your lump may not currently present as a significant concern, ongoing monitoring and professional evaluation are essential to ensure that it does not indicate a more serious condition. Your health and peace of mind are paramount, so do not hesitate to seek further medical advice.

The exact issue can only be determined through examination; most likely it is thrombosed hemorrhoids, but anal polyps and malignant tumors are also possible, although the latter is less likely.
