Perianal mass


Hello doctor, I would like to ask about a small lump that has recently appeared next to my left anal area.
The skin looks slightly bluish-purple, and there is no pain when I touch or press on it.
Could this be a tumor or something else?

Xiao, 20~29 year old female. Ask Date: 2022/01/19

Dr. Xu Kaixi reply Surgery


Based on your description, the perianal lump may be a thrombosed hemorrhoid.
If there is no significant pain, it indicates that there is no inflammation, and theoretically, it will resolve on its own over time.
To confirm the diagnosis, please visit a hospital for an examination.

More Info


When it comes to anal masses, it's important to understand that they can arise from a variety of causes, some benign and others more serious. The presence of a lump near the anus, especially one that appears bluish or purplish, can be concerning, but it does not automatically indicate the presence of a tumor. Here are some potential causes for the mass you described:
1. Hemorrhoids: These are swollen blood vessels in the rectal area that can become engorged and may appear bluish. They can be internal or external, with external hemorrhoids often being more visible. While they can cause discomfort, they may not always be painful, especially if they are not thrombosed (clotted).

2. Anal Fissures: These are small tears in the lining of the anus that can lead to the formation of a lump or tag of skin. They are often associated with pain during bowel movements but may not always be painful when touched.

3. Skin Tags: These are benign growths that can occur around the anal area, often as a result of previous irritation or inflammation. They are usually painless and can vary in size and color.

4. Abscesses: An anal abscess is a collection of pus that can occur due to infection. While they are typically painful, some may not present with significant pain initially. They often require medical intervention.

5. Fistulas: An anal fistula is an abnormal connection between the anal canal and the skin near the anus, often resulting from an abscess. They can lead to drainage and may present as a lump.

6. Tumors: While less common, both benign and malignant tumors can occur in the anal region. These may present as masses and can vary in characteristics.

Given that the lump you described is painless and has a bluish appearance, it could be a hemorrhoid or a skin tag, but it is crucial to have it evaluated by a healthcare professional. Here are some guidelines on when to seek help:
- Persistent Symptoms: If the lump does not resolve on its own within a few days or weeks, it is advisable to seek medical attention.

- Changes in Appearance: If the lump changes in size, color, or shape, or if you notice any additional symptoms such as bleeding, discharge, or pain, you should consult a doctor.

- Associated Symptoms: If you experience any other symptoms such as changes in bowel habits, significant pain, or fever, it is important to seek medical care promptly.

- Personal Medical History: If you have a history of anal or colorectal issues, or if you have risk factors for anal cancer (such as HPV infection, smoking, or a weakened immune system), it is wise to have any new anal mass evaluated.

In conclusion, while the lump you described may not be immediately alarming, it is essential to have it assessed by a healthcare provider. They can perform a physical examination, possibly conduct imaging studies, and determine the appropriate course of action based on their findings. Early evaluation can help rule out serious conditions and provide peace of mind.
