Perianal mass


Hello Doctor: Two weeks ago, I noticed a lump near my anus that felt a bit swollen and painful.
Recently, it seems to have reduced in size, and now it feels like a small round, soft, and firm marble.
I took a picture and noticed that the outer area is a bit red, but the center is black.
What could this be? Do I need to see a doctor to have it drained?

Dr. Zhang Shuhao reply Surgery


The most common causes of perianal tenderness and swelling are thrombosed hemorrhoids and anal abscesses.
If there is redness, swelling, heat, and pain, it is necessary to seek medical attention for antibiotic treatment and possibly abscess drainage.
For thrombosed hemorrhoids, warm sitz baths may provide relief.
If symptoms persist, it is recommended to consult a colorectal surgeon.
Wishing you a speedy recovery.

More Info


When it comes to understanding anal lumps, it's essential to consider various potential causes, symptoms, and the appropriate steps to take when seeking medical attention. Based on your description, it sounds like you have developed a lump near the anus that is somewhat painful, has changed in size, and has a distinct appearance with redness around the edges and a darker center.

Possible Causes of Anal Lumps
1. Hemorrhoids: These are swollen blood vessels in the rectal area that can cause lumps. They can be internal or external and may cause pain, itching, and bleeding. External hemorrhoids can sometimes become thrombosed, leading to a hard lump.

2. Anal Abscess: This is a collection of pus that can form near the anus, often due to an infection. It can be painful and may cause swelling and redness. If an abscess is present, it typically requires drainage by a healthcare professional.

3. Fistula: 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. It may cause a lump and can be associated with discharge.

4. Skin Tags: These are benign growths that can occur around the anal area. They are usually painless but can become irritated.

5. Warts: Anal warts, caused by the human papillomavirus (HPV), can also appear as lumps near the anus.

6. Other Conditions: Less commonly, lumps can be caused by conditions such as cysts, tumors, or inflammatory bowel disease.


Symptoms to Monitor
- Pain: Is the pain constant, or does it come and go? Is it sharp, dull, or throbbing?
- Size Changes: Has the lump increased or decreased in size?
- Color Changes: The redness and dark center you mentioned could indicate inflammation or a more serious issue.

- Discharge: Is there any pus or blood coming from the lump?
- Associated Symptoms: Are you experiencing any fever, chills, or other systemic symptoms?

When to See a Doctor
Given the symptoms you described, it is advisable to see a healthcare provider, particularly a gastroenterologist or a colorectal surgeon. They can perform a thorough examination, which may include a physical exam and possibly imaging studies or a biopsy if necessary. Here are some reasons to seek medical attention:
- Persistent Pain: If the pain worsens or does not improve.

- Increased Size: If the lump continues to grow.

- Fever or Chills: These could indicate an infection.

- Bleeding: Any rectal bleeding should be evaluated promptly.

- Changes in Bowel Habits: If you experience changes in your bowel movements, such as diarrhea or constipation.


Treatment Options
Treatment will depend on the underlying cause of the lump. For example:
- Hemorrhoids may be treated with dietary changes, topical treatments, or procedures to remove them.

- Abscesses typically require drainage and antibiotics.

- Skin tags may be removed if they become bothersome.

- Warts can be treated with topical medications or procedures to remove them.

In conclusion, while some anal lumps may be benign, others can indicate more serious conditions that require medical intervention. It is essential to consult a healthcare professional to obtain an accurate diagnosis and appropriate treatment. Do not attempt to self-diagnose or treat the lump without professional guidance, as this could lead to complications.
