External Anal Masses: Causes and When to Seek Help - Surgery

Perianal mass


I have hemorrhoids, but after using the restroom, I can push them back in and feel fine.
However, one day after using the restroom, I noticed a protrusion between the anus and the vaginal opening that cannot be pushed back in like my hemorrhoids.
It looks normal on the outside, but it feels like it is protruding from the inside.
It has a slightly elastic hardness and has persisted for several weeks without improvement.
I would like to know what could be causing this.
Initially, I thought it was related to my hemorrhoids and consulted a colorectal specialist, but the doctor suggested that I see a colorectal surgeon.

Based on your description, the possible conditions for this lump include lipoma, sebaceous cyst, external hemorrhoid, or other soft tissue tumors.
It is recommended that you visit a surgical outpatient clinic for an examination.

When it comes to external anal masses, it’s important to understand the potential causes and when to seek medical help. Based on your description, you have a protrusion located between the anus and the vaginal opening that is firm and elastic, and it has persisted for several weeks without improvement. This situation warrants further evaluation, especially since it differs from your typical hemorrhoids, which can be pushed back in.


Possible Causes of External Anal Masses
1. Hemorrhoids: While you mentioned having hemorrhoids, it’s essential to differentiate between internal and external hemorrhoids. External hemorrhoids can become thrombosed, leading to a hard, painful lump that cannot be pushed back in. However, since you describe the mass as firm and elastic, it may not be a typical hemorrhoid.

2. Anal Fissures: These are small tears in the lining of the anus, which can sometimes present as a mass or lump. They are usually associated with pain during bowel movements and may lead to the formation of skin tags.

3. Skin Tags: These are benign growths that can occur after the healing of hemorrhoids or anal fissures. They are usually soft and can be mistaken for other masses.

4. Abscesses: An anal abscess is a collection of pus that can occur due to infection. It may feel firm and tender and can cause significant discomfort. If the abscess is not drained, it can lead to a fistula.

5. Fistulas: An anal fistula is an abnormal connection between the anal canal and the skin. It often develops after an abscess and can present as a lump or opening near the anus.

6. Tumors: Though less common, both benign and malignant tumors can present as anal masses. Conditions such as anal squamous cell carcinoma or other types of cancer should be ruled out, especially if there are changes in bowel habits, bleeding, or other systemic symptoms.


When to Seek Help
Given that the mass has persisted for several weeks without improvement, it is advisable to seek further medical evaluation. Here are some signs that indicate you should see a healthcare provider promptly:
- Persistent or worsening symptoms: If the mass continues to grow, change in shape, or becomes painful.

- Bleeding: Any bleeding from the mass or during bowel movements should be evaluated.

- Changes in bowel habits: Such as diarrhea, constipation, or changes in stool consistency.

- Systemic symptoms: Such as fever, weight loss, or fatigue.


Recommended Steps
1. Consult a Specialist: Since your primary care physician has advised you to see a colorectal surgeon, this is a good step. A colorectal surgeon specializes in conditions affecting the colon, rectum, and anus, and will be able to provide a thorough evaluation.

2. Diagnostic Imaging: Depending on the initial examination, the doctor may recommend imaging studies such as an ultrasound or MRI to better visualize the mass and surrounding structures.

3. Biopsy: If there is any suspicion of a neoplastic process, a biopsy may be necessary to determine the nature of the mass.

4. Treatment Options: Treatment will depend on the diagnosis. Options may range from conservative management (such as dietary changes and topical treatments) to surgical interventions if necessary.


Conclusion
In summary, while your initial thought that the mass might be related to your existing hemorrhoids is understandable, the characteristics of the mass you described suggest that it may be something different. It is crucial to follow up with a colorectal or anal surgeon for a comprehensive evaluation. Early diagnosis and treatment can significantly improve outcomes, especially if the mass is related to a more serious condition. Don’t hesitate to seek help; your health and peace of mind are paramount.
