Perianal mass
Hello Doctor: Two weeks ago, I noticed a lump near my anus that feels a bit swollen and painful.
Recently, it seems to have reduced in size, and now it feels like a small, round, soft yet 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 with a lump are thrombosed hemorrhoids and anal abscesses.
If there is redness, swelling, heat, and pain, it is necessary to seek medical attention for antibiotic treatment or even abscess drainage.
For thrombosed hemorrhoids, warm sitz baths may help alleviate symptoms.
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 recognize that various conditions can lead to the development of such lumps. The symptoms you've described—pain, swelling, and the appearance of a lump near the anus—can be indicative of several potential issues. Given the characteristics of the lump you mentioned, it could be a hemorrhoid, a skin tag, or possibly an abscess.
Common Causes of Anal Lumps
1. Hemorrhoids: These are swollen veins in the lower rectum or anus that can cause discomfort, pain, and sometimes bleeding. They can be internal (inside the rectum) or external (under the skin around the anus). External hemorrhoids can become thrombosed, leading to a painful lump.
2. Anal Abscess: This is a collection of pus that can form near the anus due to an infection. It often presents as a painful, swollen lump and may be red and warm to the touch. If the abscess is not treated, it can lead to more severe complications.
3. Skin Tags: These are benign growths that can occur around the anal area, often resulting from previous irritation or friction. They are usually painless but can become uncomfortable if they are irritated.
4. Fistulas: An anal fistula is a small tunnel that forms between the end of the bowel and the skin near the anus, often resulting from an abscess. It can cause persistent drainage and discomfort.
5. Warts or Other Growths: Genital warts or other benign growths can also appear in the anal area. These are usually caused by the human papillomavirus (HPV).
Symptoms to Monitor
- Pain: Is the pain constant, or does it come and go? Is it sharp, throbbing, or dull?
- Color Changes: The redness around the lump can indicate inflammation or infection. The black center you mentioned could be concerning, as it may indicate a thrombosed hemorrhoid or necrosis.
- Discharge: Is there any pus or blood coming from the lump?
- Size Changes: Has the lump changed in size since you first noticed it?
When to See a Doctor
It is advisable to consult a healthcare professional if you notice any of the following:
- The lump persists or worsens over time.
- You experience significant pain or discomfort.
- There is bleeding from the lump or rectum.
- You have fever or other systemic symptoms, which may indicate an infection.
- The lump changes in appearance, especially if it becomes hard or develops a foul odor.
Conclusion
While some anal lumps can resolve on their own, others may require medical intervention. It's crucial not to attempt to "pop" or squeeze the lump yourself, as this can lead to infection or worsen the condition. A healthcare provider, such as a gastroenterologist or a colorectal surgeon, can perform a thorough examination, possibly including a digital rectal exam or imaging studies, to determine the exact nature of the lump and recommend appropriate treatment.
In summary, while the lump you described might not be serious, it is essential to have it evaluated by a medical professional to rule out any significant conditions and to receive appropriate care. Early diagnosis and treatment can prevent complications and ensure better outcomes.
