Anal Masses: Symptoms, Causes, and When to See a Doctor - Surgery

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 a bit.
Now, when I touch it, it feels like a small, round, soft-hard ball, about the size of a 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?

Based on the description, it may be a thrombosed hemorrhoid, caused by subcutaneous bleeding in the hemorrhoidal tissue.
It typically presents with swelling and pain, and is more likely to occur after drinking alcohol, staying up late, or consuming spicy and irritating foods.
A warm sitz bath can be helpful, along with the use of hemorrhoid ointments and oral anti-inflammatory pain relievers, which may improve symptoms.
The protruding area may reduce in size but may not completely disappear.
If it frequently recurs and affects quality of life, surgical intervention is recommended.

More Info


When it comes to anal masses, it is essential to approach the situation with caution and awareness of the potential underlying conditions. The symptoms you describe—a lump near the anus that feels swollen and painful, with a red outer area and a black center—could indicate several possibilities, ranging from benign to more serious conditions.


Possible Causes of Anal Masses
1. Hemorrhoids: These are swollen blood vessels in the rectal area that can cause lumps. They may be internal or external, and symptoms often include pain, itching, and sometimes bleeding. The lump may feel soft and can be tender to the touch.

2. Anal Abscess: This is a collection of pus that can form near the anus due to infection. It may present as a painful, swollen lump and can be red and warm to the touch. If it is not treated, it can lead to more severe complications.

3. Fistula: 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 may cause persistent drainage and discomfort.

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

5. Warts or Condylomas: Caused by the human papillomavirus (HPV), these can appear as small lumps around the anal region.

6. Malignant Growths: Although less common, anal cancer can present as a lump or mass. Symptoms may include changes in bowel habits, bleeding, or persistent pain.


When to See a Doctor
Given the symptoms you describe, it is advisable to consult a healthcare professional. Here are some reasons to seek medical attention:
- Persistent Symptoms: If the lump does not resolve or continues to grow, it is essential to have it evaluated.

- Pain and Discomfort: If the pain worsens or becomes unbearable, medical evaluation is necessary.

- Changes in Bowel Habits: Any changes in your bowel habits, such as bleeding or changes in stool consistency, warrant a doctor's visit.

- Appearance of the Mass: The fact that the mass has a black center and is red around the edges is concerning and should be evaluated by a healthcare provider.


What to Expect at the Doctor's Appointment
During your appointment, the doctor will likely perform a physical examination, which may include a digital rectal exam. They may ask about your symptoms, medical history, and any other relevant factors. Depending on the findings, further diagnostic tests such as imaging studies or a biopsy may be necessary to determine the nature of the mass.


Conclusion
While some anal masses can be benign and self-limiting, others may require medical intervention. It is crucial not to attempt to "squeeze" or drain the mass yourself, as this can lead to infection or worsen the condition. Instead, seek medical advice to ensure proper diagnosis and treatment. Early intervention can lead to better outcomes and alleviate discomfort. Remember, your health is paramount, and addressing concerns promptly can prevent complications.
